Abstract
Weed management in container plant production is a serious problem and remains one of the most expensive and time-consuming aspects of the plant nursery industry. Weeds compete for light, water, nutrients, and space, which ultimately results in decreased crop growth and yield. Weed management in container nurseries is primarily based on the use of timely preemergence (PRE) herbicides and supplemental hand weeding. The most challenging downside to applying PRE herbicides is often crop safety for many herbicide-sensitive crops commonly produced by Florida growers. Also, herbicide labels typically preclude application on bearing plants or for up to 12 months before fruit can be harvested. Due to these concerns, among the most commonly adopted non-chemical approaches to weed management in recent times is the utilization of mulch. This publication discusses best mulching practices, mulch types, application techniques, cost, and other management practices in container plant production.
