How to Germinate Alyssum

Indoor Starting

• 1

  Start the seeds indoors seven to eight weeks before outdoor planting time. Planting time for Alyssum is after all threat of spring frost has passed. Fill a starter tray with potting mix, and scatter Alyssum seeds across the top, or if there are individual pods plant one seed each. Water, keeping the soil moist but not wet.

• 2

  Set the tray in a warm sunny window or a warm location such as on top of the refrigerator. When possible set the tray outdoors in the sun on warm days.

• 3

  Thin scattered seeds in the tray to two inches apart after sprouting. Seeds should sprout within two weeks. For pod trays, re-plant any seeds that do not sprout after two weeks.

Planting Outdoors

• 4

  Rake the ground in the garden where the Alyssum will be grown. Loosen the top two inches of soil and remove any weeds.

• 5

  Scatter Alyssum seed on the surface to seed directly outdoors. For plants started indoors, set them in the ground six to eight inches apart, in a hole three or more inches deep so that the base of the seedling stem is at surface level. Water to keep the soil moist.

  Thin the outdoor propagated Alyssum to six to eight inches apart when they reach a height of three inches.
