How often should I replace mulch in Florida?
In Florida, you can expect to replace mulch in flower beds at least once a year. That’s because frequent watering can lead to quick decomposition. In other situations, such as around trees and shrubs, a layer of mulch can last longer: up to two years. Gardeners should check mulch layers regularly for signs of wear. You should always remove old mulch and replace it with fresh mulch. Adding mulch is a great way to prevent weeds from growing, keep your soil moist, and reduce erosion. But using too much or too little mulch in your garden or yard can be counterproductive.
What is the best mulch to use in Florida?
To answer this question, we typically recommend an organic mulch as it breaks down over time and enriches the soil. Examples of this include pine straw, pine bark, melaleuca chips, and other wood and leaf mulches. The answer depends on your garden’s needs. Wood mulches are excellent for retaining soil moisture, cooling the soil, and keeping weeds away. Meanwhile, pine straw is your best bet for preventing erosion.
What is the downside of mulch?
Mulch with fine grade material has very poor airflow, and will remain wet for long periods, causing many problems, including crown rot. It is bad to have low airflow and constant moist conditions in the top 50mm to 100mm around the crown of plants. When mulching around trees and shrubs, don’t pack it against the trunks and stems, where the moisture and wood-decaying organisms in most mulches can rot bark. Pay extra attention around the base of trees and shrubs.
