Weed-free nursery containers start from the ground up with the focus on prevention. The key to a successful weed management program is a strict sanitation regimen that combines cultural practices and effective use of herbicides. To prevent weed seeds from germinating and contaminating containers, follow these best management practices for clean container production:
Maintaining weed-free noncropland areas is one of the most effective sanitary practices. To drastically reduce weed seed from infesting production areas, control weeds growing along the edges of fields, roadways and drainage ditches.
Weeds between containers are a source of weed seed. And windborne weed seeds, such as bittercress and oxalis, can project seed several feet. Start with a clean foundation.
Weed seeds are often small and cling to the side of containers. Use clean pots or containers to reduce the number of weeds in your nursery. Wash propagated pots and liners inside and out with pressurized water to remove seeds. Starting with weed-free liners is critical. A single escape of one bittercress plant can produce up to 5,000 seeds!
The final step to prevent weeds from contaminating containers is to apply a preemergence herbicide, such as Snapshot® specialty herbicide, to the surface of weed-free container media. Once activated with 0.5 inch of irrigation, a chemical barrier at the surface prevents any weed seeds from germinating and competing for vital nutrients. With weeds out of the way, Snapshot specialty herbicide will help foster the development of beautiful, thriving plants.
