Weed Control

Occultation for agriculture is a term used to describe a technique, popular in Europe by organic farmers, for greenhouse weed controlling, and stale seedbed preparation. As an all-natural alternative to chemical pesticides and herbicides, this greenhouse weed control process has been quickly gaining interest and implementation here in the US.

When a black UV-treated polyethylene film is used as a greenhouse ground cover, it creates a warm and moist environment that mitigates weeds. As the soil warms, more weeds begin to come out of their dormancy. When seeds begin to germinate, they sprout into this dark suffocating environment, void of sunlight or air movement resulting in the death of the plant. The remaining plants residues are then mostly consumed by worms and other organisms involved in decomposition. 

Leave the greenhouse ground cover film on as long as necessary so that when removed, the surface weeds should be destroyed, and your soil should look clean. This technique, occultation, greatly reduces the amount of work necessary to prepare and area for planting.
