Plant Propagation:
Sweet William are grown from seeds. They can be directly seeded into your flower garden, or seeded indoors for transplanting later. For spring blooms, start indoors six to eight weeks before the last frost. Young seedlings will transplant well into their permanent home.
Sow Sweet William seeds early in the season and cover lightly with 1/8" of fine garden or potting soil. Water thoroughly once.
Transplant Sweet William into your garden after the last frost date for your area. Space them six inches apart. They will tolerate a little crowding. They will look great filling in a flowerbed, or as a border edging.
Sweet William can also be grown from cuttings or plant division.
