Alyssum Cover Crop - Pest/Weed Control

Sweet Alyssum makes an excellent cover crop for weed suppression and for attracting beneficial insects. A very large range of predatory wasp species are attracted to its tiny flowers, and will feed on caterpillars, aphids, and other pest insects while they are in the area. Sow Alyssum liberally between rows of lettuce, carrots, or Brassicas to smother potential weeds and generally improve the garden ecosystem. Once it is tilled under it will release useful carbon and organic matter.
 
Suppresses weeds
Attracts beneficial insects
Adds carbon to soil
Smells great
 
Direct sow when a slight risk of frost still exists
 
Starting
Sow seeds on the surface of the soil. They should sprout in 5 to 14 days, depending on conditions.
 
Growing
Alyssum can be tilled under or cut and composted at the end of the season. Avoid following this cover crop with other Brassicas. Excess moisture in the soil causes Alyssum to grow very vigorously.
