Tips & Advice:
Sowing Indoors
Level fill a module tray with seed compost firming with the base of another tray. Water well with a fine rose. Sow seeds individually over the surface and gently press down. Place in a propagator at 20-25°C or cover tray with cling film and leave in a warm room. Don't exclude light, and allow 2-3 weeks for germination.
Growing On
When shoots appear, remove cling film or ventilate propagator. Keep seedlings in a light position, but shade from direct sunlight. Grow on in a minimum temperature of 10°C.
Hardening Off / Planting Out
Gradually accustom plants to outside conditions for 2-3 weeks before planting out when risk of frost has passed. Allow 30cm between plants. Water well until established. Suitable for sun or part-shade in damp soils.
Aftercare
Deadhead regularly to prolong flowering and prevent unwanted self-seeding. In autumn, cut back to just above ground level.
Advice
Early sowings will flower the same year.
