Problems with Organic Mulches – Water Conservation for Lawn and Landscape? ›

Mulching at the too early in the spring can create water logged soils that may kill drought tolerant plants. Mulch applied too deeply in the fall can create a home for rodents which may feed on plant stems and trunks throughout the winter. Pull mulch away a few inches from the trunks of trees and shrubs.

Disadvantages of organic mulch

Because organic mulch decomposes, you have to replace it yearly or every few years, depending on your mulching material. Pine needles and aged wood chips can last for a few years, while grass clipping and straw will need to be replaced annually. ✗ Some mulches contain weed seeds.

Mulches aid in greater retention of water by minimizing evaporation, reducing weed growth, moderating soil temperatures, and preventing erosion. Organic mulches also improve the con- dition of your soil as they decompose.

Mulch is a protective ground covering that saves water, reduces evaporation, prevents erosion, controls weeds, and in the case of organic mulches, enriches the soil. Mulches can be classified as organic or inorganic.

Organic mulching variously improved soil temperature, soil moisture, water use efficiency, and tomato yield, which is very important for greenhouse winter cultivation in this cold zone.

Disadvantages of Mulching

Excessive mulch that is a layer more than 3 inches deep can suffocate and bury plants. In this case, oxygen and water are unable to reach the roots. A layer of 2 to 3 inches of mulch is enough.

Limitations of composting by-products are cost for site preparation and equipment, the lengthy treatment period, targeting final use of compost product, and environmental issues such as odors, and dust. Some investment in equipment and site preparation is required or recommended.

Best Mulch for Water Retention

Chunky mulch made from bark and other thick substances, like DSATCO Mulch's Lupin mulch, is great at keeping the water within the soil. This mulch provides insulation over the soil, giving your garden a cool, moist atmosphere for plants to thrive.

Rock mulch, made of rough or tumbled stones, comes in various sieved sizes and a range of colors. Stone mulch is decorative and doesn't break down at the rate organic wood chip mulch does, meaning you don't have to replace it. It also doesn't hold moisture the way wood chips and bark chips do.

When it rains on the plants you've mulched, the water has to go through the mulch before reaching the soil. If you are using organic mulch, the mulch will absorb the water before the ground; thus, the mulch will become moist.

Is organic mulch worth it? ›

Organic mulches help condition the soil, even inviting earthworms to naturally aerate the soil, and help reduce with soil compaction. While decomposing, they add nutrients such as potassium, nitrogen, phosphorus and trace elements to the soil.

The answer is pretty straightforward – mulch does not cause termites.

Inorganic mulches are materials such as stone, tumbled glass, or concrete pavers. Organic mulch is a broad group of materials with different amounts of processing that will decompose over time. Living mulches such as ground covers can compete with water, light, nutrients, and space resources.

But, generally, using organic mulch made from wood chips or bark will be the best choice. It's one of the easiest and least expensive ways to ensure the long-term health and fertility of your soil and the health of your trees and shrubs.

Advantages of Organic Mulch

Organic mulch nurtures soil and plants mainly because it decomposes over time, releasing nutrients into the soil. Organic mulch, in most cases, can be dyed and shredded to desired specifications. Organic mulch conserves water and protects from weed growth, and aids in stopping soil erosion.

Mulch materials such as shredded brush, manure, or hay from "pastures, hayfields, or street and highway right-of-ways may contain weed seeds," Baka says, as well as herbicide residues that can kill your plants.
