Can weeds grow through plastic

Killing weeds with plastic will have different results depending on the color of the material. Clear plastic raises the temperature of the soil. This can kill weed seeds and roots as well as soil pathogens and fungi. It also allows light through the plastic, which can allow heat-tolerant or hardy weeds to survive. Clear plastic is most effective during the hottest summer months.

Black Plastic

Black plastic does not raise soil temperature as high as clear plastic and will not kill pathogens or fungi. But it can be more effective at killing weeds. Black plastic blocks the sunlight so that plants cannot produce sugars through photosynthesis but using black plastic takes longer than clear plastic to kill weeds.

Resistant Weeds

Neither clear nor black plastic will eliminate every weed. Sturdy weeds can puncture the plastic and grow through either color. Heat- and drought-resistant perennial weeds or those with deep roots may be able to enter a dormant state and begin growing again once the plastic is removed.
