Pre-Emergent Weed Control Products
Corn gluten meal is a natural weed and feed fertilizer. To function as a pre-emergent, it must be broadcast before grassburs, crabgrass, henbit, dandelions, rescue and other annual weeds germinate. Possibly its best use is on bare soil around root crops, bulb plants like onions and other transplants. It will feed the young plants while keeping the competing weeds at bay. This method can also be used after seed planting but only after the seeds have grown into small seedlings. This technique works year round.
Corn gluten meal - meal form - most effective but dusty.
Corn gluten meal - granular - cleaner but less effective.
