The Great Mulch Debate| Organic vs. Non-Organic

Different Types of Inorganic Mulches

Mulching your garden or landscape plantings offers numerous advantages, such as weed reduction, moisture retention, soil insulation, and aesthetic appeal. However, selecting the right type of mulch for your requirements can be daunting.

Organic mulches are natural, nutrient-rich materials that improve soil condition by encouraging earthworms to aerate it organically. Additionally, they reduce compaction in the soil as they decompose to provide it with essential nutrients like potassium, nitrogen, and phosphorus.

Rock

Rocks are often used inorganic mulches for landscaping projects. While they add visual interest and suppress weeds, they don't provide much protection or added nutrients to the soil like organic mulches do.

Decorative rock mulches are convenient and add an elegant touch to your lawn. Not only do they suppress weeds, but they can be covered with other mulches for even greater visual impact.

They don't break down quickly and only require replacement as often as other mulches, making them an ideal choice for areas without plants or drought-resistant vegetation.

Lava rock can be an effective option for erosion control and weed suppression, though it may create issues in areas with perennial weeds. Furthermore, lava rock may cause glare from sunlight.

They have a slow rate of degradation but may need replacing periodically. Also, since they don't permit air or water penetration through the soil, they won't do well in an environment requiring frequent irrigation.

Rubber

Rubber is a durable material used in many products, such as automotive brake pads, seals, clothing, and footwear. It also produces airbags that protect passengers during auto accidents.

Rubber mulch is created from recycled tires that have been ground into a soft, cushiony surface. It's commonly used around playgrounds to help reduce injuries if kids slip onto it.

However, some experts worry that rubber mulch may contain chemicals that could seep into soil and water over time. These toxins could harm plants and athletes alike while polluting groundwater sources.

Conversely, Gravel is less flammable than rubber mulch and offers better weed control and soil protection. Plus, it doesn't decompose easily, so that it can last for an extended period.

Plastic Sheeting

If you're prepping for a disaster, stock up on plastic sheeting. This versatile material can be utilized for many projects and even temporary shelters during storms, pandemics, and other crises.

It effectively suppresses weeds and is usually covered with organic or inorganic mulches to enhance its aesthetic appeal. Unfortunately, it requires much upkeep, making it unsuitable for large trees or shrubs with deep root spreads.

One major drawback of plastic sheeting is that it prevents water, air, and nutrients from reaching the soil. This stops beneficial insects such as worms from living there and can even kill off the soil.

Inorganic mulches come in many forms, such as rocks or Gravel, landscaping fabric, and rubber mulch. Since these don't degrade or break down over time as organic mulches do, they're more cost-effective than organic alternatives and don't need reapplying or topping off as organic mulches do.

Geotextiles

Inorganic mulches are an excellent way to add visual interest and protect delicate plants in a landscape. Furthermore, they help warm soil temperatures for early planting in the springtime.

Furthermore, they suppress weeds and prevent the growth of mold or mildew. But unfortunately, they don't add any essential nutrients to the soil and can become damaged when exposed to sunburn.

Engineers often utilize geotextiles to separate the layers of a roadway. This helps keep the road from sinking into the soil, as water can easily pass through these geotextiles and out of the roadway.

Geotextiles have another popular use as a stabilization material. Laying a layer of geotextiles over wet compressible soil transforms it into an inert base that can serve as the foundation for buildings or other structures.

Woven and non-woven geotextiles can both be used for this application. The woven variety is more durable, offering greater strength; conversely, non-woven geotextiles offer flexibility and breathability.

Benefits of Organic Mulch

Organic mulches offer an extra layer of protection over the soil. Not only do they prevent weeds, conserve moisture, and reduce fertilizer use, but they can also prevent soil erosion.

Organic mulches can be made from materials like hay, straw, grass clippings, leaves, sawdust, compost, and rice hulls - which decompose over time and improve soil quality.

Improves Soil Quality

Organic mulches improve soil quality in several ways, such as decreasing weed growth and improving its capacity to retain moisture. They also enhance the soil's aeration, making it more fertile.

Mulches can enhance the aesthetic appeal of a garden or landscape. When used correctly, mulches fill in any bare spots in soil and give your landscape an overall polished appearance.

Mulches also help keep the soil cool during hot weather, especially for young plants whose roots could be permanently damaged by excessive temperatures.

Organic mulches such as straw or hay can effectively prevent weed seeds from germinating and taking root. Still, those already present can penetrate the mulch - so weeding is necessary after spreading it.

Reduces Soil Erosion

Organic mulches help to prevent soil erosion by soaking up rainwater and keeping the soil in place. This allows water to release slowly, avoiding runoff that could harm nearby areas like driveways or sidewalks.

Organic mulches also help regulate soil temperature, allowing roots to breathe without overexposing them to high temperatures that could harm or kill them. This is especially helpful during hot weather when organic mulches help keep the soil cool.

Organic mulches come in many forms, such as grass clippings, withered plants, and compost. Each has its advantages and should be tailored to the soil conditions where it's applied.

Prevents Weed Growth

Organic mulches block weed seeds from sunlight and prevent them from germinating, particularly if you use bark mulch as a cover. Furthermore, organic mulches can prevent seedlings from taking hold by depriving them of sunlight and nutrients.

Mulches can also retain soil moisture by shielding the soil's surface from evaporation, helping keep plants healthy and reducing watering requirements.

Mulching can effectively combat weed growth but must be combined with other weed control measures. The two primary approaches should be crop rotation and measures that limit or prevent weed propagation.

Increases Soil Moisture

Mulching with organic materials improves soil's ability to retain moisture, helping your garden plants remain healthy and vibrant. It also reduces the need for watering or weeding, which is necessary for healthy plant maintenance.

Organic mulches are composed of elements found naturally, such as wood chips, grass clippings, pine needles, leaves, and hay. These highly functional natural mulches add aesthetic value to your landscapes and planting beds!

These natural mulches also reduce evaporation, keeping plants' roots protected from cold weather exposure. This is beneficial for plants that prefer warm temperatures and those susceptible to sudden changes in temperature.
