Thin or transplant seedlings about 8-10 inches apart. Harden off seedlings started indoors before transplanting to permanent location. One to two weeks at 60 F. Keep soil moderately moist during germination. Nemesia is best started early indoors where summers are hot. Shear back plants after initial flowering period for possible later blooming.
Plants prefer a mostly sunny spot with fairly rich and somewhat moist well drained soil.
Pinch back plants when young for bushy growth habit.
