Where, When and How to Plant Alyssum
Grow alyssum in well-drained, humusy soil that holds moisture well in the summer. Hot, dry spells cause alyssum to stop flowering and potentially dieback. Alyssum needs at least 4 to 6 hours of direct sun to flower well. Grow alyssum planted directly in the garden from seed, started as seedlings indoors 8 to 10 weeks before the last frost date, or purchased as a transplant from the local garden center. Alyssum started directly in the garden from seed will bloom later than those started or purchased as transplants. Sow seeds or plant transplants in spring after all danger of frost has passed. Simply sprinkle seeds in the soil bed and lightly press them into the soil. Keep the soil evenly moist and they will germinate within one week. Grow alyssum tightly together in groups spaced only 6 inches apart to create a quicker flowering carpet effect.
Alyssum Growing Tips
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. When grown in containers or small spaces with little soil, fertilize monthly to keep them growing strong.
Regional Advice and Alyssum Care
Alyssum will self-sow readily in our climate. However, the seedlings tend to have poorer quality flowers so it’s best to remove them and start again with fresh seed or transplants each year.
Companion Planting and Design
Sweet alyssum grows best where it can be showcased. Plant or sow seeds in front of flower borders, in containers with other taller growing annuals, such as salvia and profusion zinnias, and in walls or rock gardens among other low growing perennials and wildflowers, such as columbine.
