When planting alyssum, scatter seeds and press them lightly into the ground. Don't cover the seeds, as they need light to germinate. Although alyssum are quite drought tolerant, they can look a little droopy during the hot days of summer. Shear plants back by half and water regularly. This will bring about new flowers.
Alyssum makes an excellent, nearly instant ground cover. They are an economical way to fill in garden space and work well to crowd out weeds.
