As greenhouses become empty, take the opportunity to thoroughly eliminate weeds and algae, and sanitize benches and work areas to prevent problems for the next crop cycle.
Weeds are a persistent problem in both retail and wholesale greenhouses.
Weeds are unsightly and harbor insects such as whitefly, aphids, thrips, and other pests such as mites, slugs and diseases. Therefore, the removal of weeds from greenhouse floors is important for the purpose of pest management as well as aesthetics. An integrated weed management program will effectively manage weed populations. These methods will only remove the vegetation which is present, but will not prevent reestablishment from seed which will also be present. Even solarization rarely produces sufficient heat to effectively kill weed seed.
