Managing WeedsUnit 1.10 | Part 1 – 405c) Living mulches: Intercropping with a cover crop in main season crop can prevent
erosion and limit weed growth. Living mulches are important in low- and no-till systems
to suppress weed growth during the cropping season (see Unit 1.2, Garden and Field
Tillage and Cultivation).
- Results of weed suppressive mulches
a) Effectively inhibit growth of most weeds if applied as a thick layer (3” or more if using
organic materials)
b) Keeps soil cool
c) Minimizes water loss
- Limitations of weed suppressive mulches
a) Potential problems with fungal diseases, especially if applied too close to stems or tree
trunks
b) May harbor snails, slugs, and other pests
c) Labor intensive to apply
d) Purchasing mulch increases input costs
