Can Alyssum Be Cut Back?

Although this annual blooms dependably throughout summer and into fall, it looks better with occasional trimming. A light prune removes the spent flowers and leggy stems so the alyssum maintains its dense mounds of foliage and blooms.

How do you keep alyssum blooming all summer?

Keep alyssum well-watered during hot, dry weather. It has few pests and diseases. In mid summer to stimulate more growth and flowering shear your alyssum plants by 1/3rd of their height. Fertilize afterward with a balanced product and water and they will regrow for a late summer flower show.

How do I bring my alyssum back to life?

This plant prefers moist, well-draining soil. Keep it well watered, especially during the hottest parts of the summer. If they are left to become too dry for too long, they will die early. To potentially revive alyssum when this happens, cut the plant back by one third, and return to a diligent watering regimen.
