Surface to barely cover
Seed To Bloom:
Sow indoors in pots 8-10 weeks before last frost. Discourage any damping off by watering from below, placing pots in a tray of water and then allowing to drain. Keep at 65-70°F.
Make an additional sowing in late July for flowers until late fall.
PLACEMENT & CULTIVATION
Nemesia must have cool weather to bloom with abandon; the petite flowers completely cover the spring-green narrow foliage when cool weather reigns. This means, for most gardeners, an early start indoors to have them mature before the heat of summer is inescapable. In cooler summer areas, they bloom non-stop. Resow in mid July for fall flowers. In warmer regions, they are fall planted.
Keep evenly moist, especially in full sun, but avoid saturated soils.
Slightly acidic to neutral
Mix in a couple of inches of compost prior to planting.
Diseases & Pests:
Avoid root disease by planting in a well-drained location.
When to Cut for Bouquets:
Cut when 1/2 to 3/4 of flowers on a stem are open.
