Introduction to Mulch and Water Conservation

Mulch is a material that covers the soil surface, providing a layer of protection. It can be made of various materials such as wood chips, leaves, or straw. While mulch may seem like just another landscaping element, its role in water conservation should not be underestimated. In this post, we will explore why water conservation is important and how mulch can help with water conservation efforts.

Why Water Conservation is Important

According to the United Nations World Water Development Report 2019, over 2 billion people live in countries experiencing high water stress or scarcity. This means that their access to clean and safe drinking water is limited or restricted. Additionally, climate change has led to an increase in extreme weather events such as droughts and floods which further exacerbate these issues.

Water conservation is crucial because it helps ensure that there is enough freshwater for both human consumption and wildlife habitats while also preserving ecosystems. Conserving water also reduces energy use associated with pumping and treating wastewater.

The Relationship between Mulch and Water Conservation

Mulch plays an influential role in conserving soil moisture by reducing evaporation rates and suppressing weed growth. These are just some of the ways that mulching impacts the environment for good:

  • Retains Moisture: The shade cast by the layer of mulch helps reduce moisture loss from soil through evaporation.
  • Decreases Weed Growth: Mulching prevents weed seeds from getting the light they need to germinate.
  • Insulates Soil Temperatures: Mulching acts as a thermal blanket moderating soil temperature extremes during hot summers or freezing winters.
  • Nutrient-rich Soil: As organic materials break down under mulch layers nutrients are released into the soil improving plant health.

These benefits combined make healthy plants less reliant on constant watering making it perfect for arid regions where there’s limited annual rainfall or poor irrigation systems.

A study conducted at Colorado State University found that using mulch reduced irrigation needs by 20-50% over a five-year period. Mulching raised-bed gardens with straw reduced the water required during dry seasons in comparison to un-mulched gardens. This led to an estimated cost savings of $223 per 1,000 square feet.

Mulching can be eco-friendly and cost-effective making it beneficial for the environment, your landscape, and your budget.

Using mulch as a part of your landscaping plan is just one way you can contribute to water conservation efforts. There are several other ways that you can conserve water such as collecting rainwater and fixing leaks in your home. Small steps taken by individuals can collectively make a big difference in conserving precious freshwater resources.

Concluding Thoughts

Water is a vital resource that is essential for all life on earth but is increasingly becoming scarce in some parts due to climate change, droughts, floods, among other factors. Conserving water has become more important than ever before.

Mulching can be considered as an innovative contribution towards easing the concerns around insufficient water supply by removing drastically the amount of water required for irrigation system thereby leaving more available for household and other use resulting in savings on monthly bills while contributing positively to environmental sustainability which we should all strive towards achieving.

What is Mulch?

Mulch is a layer of material that is spread on the surface of soil to conserve moisture, suppress weeds, regulate soil temperature, and improve the fertility of the soil. [Wikipedia]

Mulch Types and Their Water Conservation Benefits

Mulch is a term used to define any material which is spread or laid over the soil as a covering. The benefits of mulching are many, including reducing water loss, suppressing weed growth, while regulating the temperature of the soil.

The ability of mulch to minimize water loss makes it an important component in water conservation practices. Organic and inorganic mulches can be used to retain moisture in the soil. Some organic and inorganic materials also help with drainage and prevent soil erosion.

Organic Mulches

Organic mulches come from natural sources such as wood chips, grass clippings, leaves, bark pieces and pine needles. They eventually decompose into organic matter that helps improve overall soil health by improving its nutrient content.

Benefits of using Organic Mulches
  1. Moisture retention: An organic cover can significantly reduce evaporation rates from the underlying soils which results in moisture conservation.
  2. Weed control: One significant advantage of applying an organic cover is that it suppresses weed germination and growth effectively.
  3. Nutrient contribution: As it decomposes gradually over time an organic layer contributes nutrients back into the ground that plants can absorb.
  4. Temperature regulation: This type of covering helps to regulate temperatures at extreme cold or heat levels by acting as insulation for root systems.
Types of Organic Mulches
  1. Wood Chips – Made from timber waste materials such as branches or logs after pruning or thinning activities have been carried out on trees, wood chips provide excellent moisture retention properties along with weed suppression qualities when applied 3-4 inches deep.
  2. Grass Clippings – Grass cuttings act as a good source of nutrients since they break down easily due to their green matter content.
  3. Leaves – Leaves add carbon-based organic material back into soil profiles while they decompose. They are beneficial for amending heavier clay soils.
  4. Bark Pieces – Bark pieces, similar to wood chips, provide excellent water retaining qualities when laid out in a sufficiently thick layer to prevent drought stress.
  5. Pine Needles – These small leaves make a durable and long-lasting cover as they break down slowly contributing nutrients back into the soil.

Inorganic Mulches

Inorganic mulch materials include rocks, gravels, fabrics or plastic films that do not decay but instead act as barriers against UV radiation and moisture loss.

Benefits of using Inorganic Mulches
  1. Longevity: Unlike organic materials, inorganic covers do not break down and so help keep the soil structure intact over time which is beneficial for areas exposed to erosion factors and heavy foot traffic.
  2. Weed Control: By forming physical barriers developed from thicker materials more specifically selected for this purpose.
  3. Water Conservation: Impenetrable surfaces like gravel can effectively reduce evaporative losses since it limits the amount of sun exposure the underlying soil receives.
Types of Inorganic Mulches
  1. Landscape Fabrics – Prevent weed growth by providing a strong barrier while allowing water penetration through their porous surface area.
  2. Plastic Film Sheets – With 100% coverage available preventing sunlight penetration with white-on-black polythene sheeting is key because it will block almost all light from transmitting through onto any plantings or seeds thereby killing them off or preventing germination entirely.
  3. Gravel Stones – A layer of well-draining river rocks on top of soils will greatly increase moisture retention by reducing evaporation rates while also adding stability against erosion.

Mulching provides many benefits including water conservation advantages such as moisture retention which helps plants survive through periods of drought stress while maintaining soil health with nutrient inputs added gradually over time during decomposition processes accelerated by microbial activity from surrounding bacteria. Both organic and inorganic cover types are useful as they each can perform unique functions where required specifically enhancing or creating beneficial conditions for certain crops while also helping reduce maintenance time and costs through weed control and the establishment of healthy soil profiles for long-term sustainability purposes.

Mulching Techniques for Different Climates

Mulch is a vital part of gardening because it helps conserve soil moisture, control weeds, and regulate soil temperature. It also adds organic matter to the soil as it breaks down over time. Whether you live in an arid or wet climate, mulching can help your garden thrive despite environmental challenges.

Mulching Techniques in Arid Climates

Arid climates are characterized by low rainfall, high temperatures, and lots of sun exposure. Under these conditions, plants lose water quickly through evapotranspiration. To combat water loss and keep plants healthy, arid gardeners need to use mulch.

Applying Mulch in Arid Climates

To apply mulch in arid climates:

  • Wait until the soil has warmed up before applying mulch.
  • Water the area where you plan to lay down mulch before applying it.
  • Apply a layer of weed barrier fabric (optional).
  • Spread a 3-inch layer of organic material such as straw or leaves.
  • Keep the area around plant stems free of mulch to prevent rot.
Best Types of Mulches for Arid Climates

When choosing a type of mulch for an arid climate landscape, consider these options:

  • Organic materials: These types of material retain moisture well while slowly decomposing into the soil.

    • Straw
  • Leaves

  • Bark chips

  • Compost

  • Rocks: They work great as they don’t absorb moisture from the air but extreme heat may affect them too much causing overheating that’s not favorable for your plants.

    • Gravel rocks
  • Lava rocks

Mulching Techniques in Wet Climates

Wet climates have high rainfall and humidity levels. Excessive moisture can cause fungus growth on plants and make weeds grow faster than usual. Fortunately, proper application of mulch can protect plants from splashing mud and slow down weed growth.

Applying Mulch in Wet Climates

To apply mulch in wet climates:

  • Wait until the soil has warmed up before applying mulch.
  • Remove weeds and debris before laying down mulch.
  • Apply a layer of 2 to 4 inches of organic material such as compost or bark chips.
  • Don’t apply too much mulch or pile it against plant stems to prevent moisture from staying on them for too long, this may cause rotting.
  • Use regional species for your garden because they’ve already adapted to the environment locally and are less prone to diseases.
Best Types of Mulches for Wet Climates

When choosing a type of mulch for wet climate landscapes, consider these options:

  • Shredded leaves: They’re light, easy to spread and help provide high levels of nutrients to soil.
  • Wood chips: They’re long-lasting, great at preventing seed germination but do not break down easily like straw so choose according to your needs if you want enriched soil or not.
  • Grass clippings: These are perfect for temporary cover, the grass is moist enough when freshly cut so there won’t be any need for irrigation right after application. If allowed to dry off, then they become insoluble which will lead to water constraints thus hindering penetration into the soil.

Mulching techniques vary based on weather zones and environmental characteristics; selecting appropriate materials makes all the difference between an attractive garden bed with lush plants happy despite different climates and a neglected one that’s more susceptible towards wilting due to unfavourable conditions – do take care folks!

How Mulch Reduces the Need for Irrigation

Mulching refers to the process of covering the soil around plants with a layer of organic or inorganic material. This practice is quite popular among gardeners, farmers, and landscapers. Mulch offers many benefits including weed suppression, soil temperature regulation, and moisture retention. One of the most significant advantages of mulching is its ability to reduce watering requirements through conservation techniques that preserve water resources without sacrificing crop yield or quality.

Understanding the Role of Mulch in Reducing the Need for Irrigation

Mulch plays a critical role in reducing irrigation needs by shielding soil from direct sunlight, wind, and other environmental elements that cause evaporation. When un-mulched soil is exposed to these conditions, moisture at the surface evaporates at an accelerated rate leading to dryness which can also destroy topsoil structures resulting in compacted soils that repel water rather than absorb it.

On sunny days, irrigating crops may be necessary twice daily using large amounts of water in efforts to keep them alive as well as healthy. Temperature control with mulch will help reduce how much water gets used up because shaded soil helps protect the plant roots while retaining moisture so they need less water overall. Moreover, mulched soil can retain more moisture from rain or irrigation applications longer than un-mulched soils thus limiting or even eliminating the need for additional watering between those events.

Crops perform best when grown at moderate temperatures between 60-75°F (15-24°C). Direct exposure to extreme heat can stunt their growth and cause irreparable damage during scorching heat spells on arid land areas. In addition to shade creation and stimulation of root growth via microbial interaction more retained vital nourishment would ensure optimal growth rates making plants stronger against high heat temperatures protecting them all year round even through droughts.

Measuring the Impact of Mulch on Irrigation Needs

Mulch impacts the amount of water required to irrigate crops significantly. The water requirements of mulched plants are reduced depending on many factors, such as soil type, crop type, and weather conditions among others giving optimal plant growth for your garden.

Studies have proven that mulched soils require up to 50% less irrigation than un-mulched soils. Mulch helps regulate soil temperature by conserving both heat and moisture at the surface level with a layer of biodegradable materials laid over an entire garden. This protective cover provides ample shade around tender roots allowing for maximum nutrient absorption that promotes curb side water collection in modern-day gardening.

During hot summer months when watering is most critical; it’s always good to use drip irrigation over standard but supplying every part of the soil with equal amounts of saturation at a faster rate which supports less evaporation time overall. Drip applications slowly release small volumes of water directly into the root zone where it can get absorbed efficiently boosting hours per day without losing nutrition through dry spells. Installing an efficient drip system or any other similar structure before applying organic matter ensures optimum results without additional stress on crucial resources like H20.

The Role of Mulch in Soil Moisture Retention

Mulching is a process used to cover the soil surface surrounding trees, vegetables, or other plants with any kind of material that protect, insulate and improve the soil in some way. One of the main reasons why gardeners add mulch to their plants is to conserve moisture in the soil. Mulch prevents water from evaporating rapidly by reducing evaporation from soil surfaces. With adequate mulching techniques, it is possible to reduce your overall watering needs by approximately half.

How Mulch Helps Soil Retain Moisture

Here are some ways of how mulch helps soil retain moisture:

  • Acts as a barrier: When you put layers of mulch on top of each other, this prevents water from evaporating quickly since it acts as a barrier for air circulation.
  • Suppresses weed growth: Weeds can also soak up water intended for your plants. By laying down ground covering materials like wood chips or grass clippings amongst others that don’t encourage weed seeds to grow well.
  • Aids decomposition: Nitrogen-rich materials such as dry leaves or grass help break down slowly over time into humus – an organic material that works best when added directly to beds themselves rather than via compost piles which may not have enough nitrogen content for rapid microbial activity
  • Insulation: During hot summer months when temperatures can skyrocket above normal range, mulch provides insulation that prevents over-evaporation and helps maintain adequate moisture level just beneath its surface.
  • Bioactivity support: Lastly, certain types like comfrey provide excellent habitat potential for more beneficial microbes such as earthworms while also helping defend your vegetable garden against potential pests.

All these benefits are essential aspects needed for proper plant growth and health. It’s important to choose appropriate kinds depending on where you live; otherwise over-mulching can stress roots leading towards higher levels of diseases.

Best Mulching Techniques to Retain Soil Moisture

As there are pros and cons, learning the proper techniques for applying mulch and their types makes all the difference. Here are some of the best mulching techniques to retain soil moisture:

  1. Know your soil type: Understanding what type of ground you have where your plants grow helps determine how much water it needs and how quickly it drains.

  2. Spread evenly around bushes/trees: This can help trap in enough moisture by covering roots which is vital during drought conditions or high temperatures. Simply spread a 3-4 inch layer over exposed dirt but avoid touching tree trunks since this promotes rot growth due to wood being exposed more.

  3. Use organic materials: Some materials can restrict air circulation leading towards increasing likelihood fungus/mold problems; healthy mushrooms help provide nutrition while also damaging other plants.

  4. Do not mix with soil/compost: Since mulch degrades slowly whilst compost decomposes rapidly, mixing them together slows down your landscaping’s overall biological activity though doing so in excess dramatically affects pH levels making it uninhabitable for most good bacteria housing themselves nearby plant structures thus causing high mortality rates when only topsoils aerated well enough effectively supporting underground organisms going through predators at rapid rates.

To properly maintain water retention and improve growing conditions, gardeners should choose carefully how they lay out their mulch beds depending on individual needs such as shade level, drainage characteristics, bug activity preferences or crumbly/textured dirt walls since each kind has its advantages/disadvantages during particular settings throughout various upcoming seasons apart from just those specific time periods of arid climates found in certain areas around different countries worldwide today.

Mulch and Erosion Control

Mulch is one of the most effective ways to retain moisture in soil, making it a key component of water conservation initiatives. However, mulch also plays an important role in controlling soil erosion. Here’s how:

How Mulch Controls Soil Erosion

Soil erosion occurs when wind or water carries away topsoil, leaving behind bare and nutrient-poor ground. This can lead to decreased soil fertility, loss of vegetation, and problems with water quality as eroded sediment finds its way into streams and other bodies of water.

One way mulch helps prevent soil erosion is by slowing down the speed at which runoff water moves across the soil surface. When rainwater hits mulch-covered soil, it is absorbed more slowly than on bare ground, giving it time to seep into the soil rather than causing runoff.

In addition to slowing down runoff velocity, certain types of mulches can also help bind the soil together to prevent erosion caused by wind. For example, straw or hay mulches create a tangled mat that holds loose soil particles in place even during heavy winds.

Another mechanism through which mulch controls erosion involves its ability to protect delicate root systems from being washed away. As a layer forms over the planting bed or garden area with enough depth — normally no less than 3 inches thick — plants are protected by anchoring their roots safely into this “blanket” beneath them.

Best Types of Mulches for Erosion Control

When selecting the best type of mulch for controlling erosion in your landscape or garden bed projects, there are several options you can consider depending on your specific needs.

Straw and Hay: Straw and hay are two affordable types of organic mulches popularly used by farmers and landscapers alike due to their efficiency against intense winds in open fields and other exposed areas where pests may be hard to avoid using synthetic pesticides over long periods. They both provide an excellent first line of defense against soil erosion, although hay is less commonly recommended because it presents more potential issues with weed germination that can become hard to manage in the long term.

Wood Chips: Most local tree care/landscape businesses offer ground-up hardwood mulch products that are a popular choice for landscaping urban environments or areas with significant foot traffic due to their capacity to create visually stunning contrast and durability over time. Wood chips work particularly well for slope stabilization and consist of fallen branches and other wood materials ground into pieces no larger than 3 inches up to 12 inches depending on the quality at which they were processed.

Coconut Fiber: Also known as coir, coconut fiber is an organic alternative often used in wet locations where water tends to cause severe soil compaction problems after rainfalls such as swale banks, meadows or low-lying garden spaces close to slopes. Being lightweight and effective in resisting runoff forces while absorbing moisture relatively quickly, this mulch is ideal for hydroseeding projects too where retaining turf growth during seed germination is essential.

Other Types of Mulch: There are many other types of mulches you can choose from when trying to prevent erosion including enviromat products featuring fast-growing live vegetation capable of binding together loose soil particles through root systems alone. Additionally, geotextile fabrics have been implemented from synthetic woven structures specifically designed as sturdy substrates laying on top of soils prone to slipping away (highly sloped areas) allowing operators to anchor trees or vegetation without further ne’er-do-well surprises by major shifting due to precipitation changes.

The Bottom Line

Mulch has multiple benefits associated with water conservation practices like reducing irrigation needs by conserving moisture levels in the soil. Erosion control plays an additional important role in maintaining agronomic health over turfgrass lawns and protecting delicate root systems making them essential components for any sustainable landscape project out there. When it comes to controlling erosion, selecting the right mulch type is just as important as proper installation methods, so be sure to select your materials thoughtfully and consult with a professional landscaper when in doubt.

Mulch and Drought Tolerance of Plants

Mulch is one of the most effective ways to conserve water in landscaping and gardening. It reduces moisture evaporation from soil, regulates temperature, and promotes healthy plant growth. However, not all mulches are created equal when it comes to drought tolerance.

Effects of Mulch on Drought-Tolerant Plants

Drought-tolerant plants are known for their ability to survive under limited water supply conditions. They have adapted various mechanisms such as succulent leaves, deep root systems, and thick cuticles that enable them to retain enough moisture for growth and development.

Despite their resilience to drought, these plants still need adequate water supply during prolonged dry spells. This is where mulch comes in handy. When applied around the base of drought-tolerant plants, mulch conserves soil moisture by:

  • Reducing soil evaporation: Soil exposed directly to sun and wind loses moisture faster than shaded soil covered with mulch.
  • Preventing runoff: Whenever rain falls at a faster rate than the soil can absorb it, the excess water runs off taking with it essential plant nutrients along with the topsoil.
  • Regulating soil temperature: Mulched soils remain cool even in hot weather reducing stress on plant roots.
  • Suppressing weed growth: Weeds not only compete with your drought-resistant plants for resources but also encourage evaporation by shading covered surfaces.

In addition to these benefits, organic mulches enrich the soil over time as they decompose improving nutrient density which enhances your plants’ overall health.

Best Mulches for Drought-Tolerant Plants

The choice of a suitable mulching material plays a significant role in ensuring optimal growth conditions for your drought-resistant plants while using minimum amounts of water. Here are some of the best options to consider:

  • Shredded Bark – This is a popular choice thanks to its availability and effectiveness at reducing water loss from soil. You can use either hardwood or softwood bark depending on your preference, but keep in mind that softwood mulches tend to be more acidic than hardwoods.
  • Straw – It is affordable and easy to find making it the best option if you have a large area to cover. However, since it decomposes quickly you need to reapply it often.
  • Compost – In addition to being an excellent mulching material, compost adds important nutrients to the soil making it an all-around soil enhancer.
  • Leaves – Leaves are cheap when they are readily available during autumn fall season. They are highly effective at controlling weeds and retaining moisture in soil.
  • Gravel/ rocks – If cosmetic appeal is desired alongside functionality then gravel or rocks could be used as a decorative feature for water conservation. Avoid using them around young plants as they take up some of the water.

When choosing a mulch for drought-tolerant plants always look out for flexibility, durability, particle size and color. A suitable mulch should have small particles which easily compact together providing additional insulation against dry weather conditions.

Mulch as a Sustainable Water Conservation Practice

Mulching is a sustainable practice that can help ensure the health and growth of plants while promoting water conservation. Mulch is essentially material used to cover the soil around plants, creating a protective layer that helps retain moisture in the soil. Mulching techniques are being promoted globally because they possess numerous sustainable benefits. This article outlines the sustainable benefits associated with using mulch as a water conservation practice, along with some of the best sustainable mulching techniques.

Sustainable Benefits of Using Mulch as Water Conservation Practice

  • Prevents Weed Growth

    Weeds compete with garden plants for nutrients and water, which can lead to stunted plant growth or even death. When you plant your garden beds and surrounding areas, weeds should be controlled at all times; otherwise, they will steal essential nutrients meant for your garden. By using organic mulches such as wood chips and straw instead of synthetic herbicides to eliminate these invasive species from your lawn, you can switch to environmentally friendly gardening practices.

  • Reduces Water Evaporation

    Mulching limits transpiration by reducing evaporation rates, keeping the soil moist for longer periods. Organic mulches also break down over time and enrich soils through much-needed nutrients such as nitrogen and phosphorus released during decomposition. Placing three or more inches of mulch on top of your soil inhibits weed germination while conserving precious water resources at the same time⁠—up to 30% if done correctly!

  • Regulates Soil Temperatures

    Organic materials like leaves, grass clippings are an excellent way to regulate soil temperatures in garden beds due to their high insulation qualities. For example, during hot summers here in Northeast Ohio, surface temperatures can rise above 100 degrees Fahrenheit if exposed directly to sunlight without shade coverage or any other insulating material around them (like plastic). Properly applied Mulches prevent this overheating issue.

  • Encourages Beneficial Organisms

    Mulching can provide a comfortable environment for beneficial insects such as ground beetles and spiders, which help control populations of harmful pests. Mulch provides an ideal habitat for worm colonies beneath the soil’s surface, which aerate soils and improve overall plant root health.

  • Reduces Soil Erosion

    With our increasingly unpredictable weather patterns putting more stress on landscapes everywhere, proper water usage has become more critical than ever. Heavy rains can quickly erode the soils in gardens or flower beds where there isn’t sufficient vegetation holding them together. However, mulching conserves water by slowing down the runoff from rainfall while strengthening existing plant roots to resist erosion over time.

Best Sustainable Mulching Techniques

Now you know how important mulching is, here are some sustainable mulching techniques that will benefit both your garden and the environment:

  • Organic Mulches

    Organic Mulches refer to materials containing living organisms like leaves, straw grass clippings and sawdust. These break down much slower than synthetic selections do and are better for making nutrient-rich compost after they degrade entirely.

  • Artificial Mulches

    Artificial Mulches like black plastic sheets or rubber mats are often less environmentally friendly than natural alternatives because they do not biodegrade or decay nearly as fast. Choosing these types of substances mainly depends on your budget vs eco-friendly standards.

  • Strategic Placement

    One aspect of responsible mulching is strategic placement. This technique ensures that plants have adequate space between each other so air circulates around their bases properly—strategic placement means understanding root growth habits⁠—planting spreading shrubs towards outer edges while keeping free lawn spaces in between plants.

  • Layering Method

    Layering method allows organic matter to decompose over time and mix with underlying soil layers for longer-lasting benefits. A layer of lightweight organic material that’s 1 inch thick; this help preserves moisture in dry soil, blocks sunlight, and reduces weed growth.

Tips and Tricks for Effective Mulching to Save Water

Mulch is an essential tool that can be used to help conserve water in gardening. When properly applied, mulch helps to suppress weeds and retain soil moisture, reducing the need for frequent irrigation.

Mulching Best Practices

  1. Choose the right type of mulch – There are many types of mulches available, including organic and inorganic options. Organic mulches such as wood chips, straw or compost are great at retaining moisture while improving soil quality. Inorganic mulches such as gravel or rock can also aid in weed suppression but don’t provide any assistance with soil nutrients.

  2. Apply the correct amount of mulch – A layer 2-3 inches thick is recommended when applying organic mulch. Any less will not provide sufficient coverage while too much may prevent adequate airflow to the soil which could lead to problems like root rot.

  3. Use fresh/dried leaves – Dried leaves are free and a proper alternative for expensive store bought fertilizer because they break down over time adding valuable nutrients back into the garden’s soil instead of taking up space in landfills inhibiting growth elsewhere.

  4. Time your application – You should apply your desired kind of mulch early during the gardening season, preferably after you have prepared your bed by cultivating soil check planting needs first.

  5. Proper placement around plants – Careful consideration should be taken on how you distribute your Mulc h Material evenly around plants without covering them completely; otherwise they won’t receive their required sunlight needed for photosynthesis

  6. Combine different types of Mulches As long as they aren’t conflicting (Example: Peat Moss mixed with leaves), many types work well together assisting each other’s capability within any given project.

Mistakes to Avoid When Mulching for Water Conservation

  1. Over mulching – Applying too much mulch can lead to plant diseases because there is an over-accumulation of moisture under the layer and reducing oxygen that plants need in their roots

  2. Not using weed barriers – Using weed barriers with your mulch is essential in gardens prone to weeds.

  3. Choosing wood chips from untrusted sources – Wood chips should be clean not infected with pests or fungi, ‘greened’ (still decomposing) so they can attract unwanted critters.

  4. Mixing materials – different types of mulches shouldn’t be mixed together unless done so knowingly and without negative impact on soil health or plant growth requirements

  5. Keeping old clippings from last year’s gardening season when new seasons require a fresh start so as not to introduce any unnecessary invasive organisms that could harm your new plants.

As a general rule-of-thumb, if you are unsure whether an action will hinder growth or not while still stabilizing soil/ surroundings for additional hydration retention use trial and error until you are comfortable doing it the right way to save water effectively!
