Mulch is decomposed material. It is the final component to the cycle of life. This is why mulching is crucial for healthy plant and shrub growth and adequate nutrition. And in addition to making for a healthy garden bed, mulch also brings vibrant color to your yard.
Mulch is vital to keeping your shrubbery hydrated and healthy, helping preserve and retain water. This effectively adds to the water source for a root structure in a controlled manner. moreover, extreme temperatures, whether too hot or too cold, could kill your tree and shrubs quicker than dehydration. But adding mulch to the base insulates and helps regulate temperature to incubate healthy growth for strong, healthy roots.
When used without a weed wrap, ironically, mulch prevents weed growth. This is because when the mulch breaks-down and decomposes it blankets soil and decays into the nutrient bank for the plant. When used over a weed wrap, it sits around the plant base and decays at a much slower rate acting as a catchall for spores and seeds. Weed growth around your plant will lead to root competition, depriving your plants of the nutrients and water they need to flourish.
The added nutrients mulch provides ideal incubation for all organic growth. Such organic material as dry leaves, twigs, wood chips, compost, grass clippings and straw serve as excellent mulch, feeding the soil and giving new life as it decays. This effectively encourages microbe growth and shelter for earthworms, which churn the soil and prevents soil compaction. This is fundamental to a healthy root structure because when soil is compacted, it is not possible for it to retain moisture and promote root growth.
