Germination Instructions
Sow indoors 6-8 weeks before last expected frost or sow directly from April. Surface sow onto moist, well drained seed compost. Just cover with a sprinkling of soil. Ideal temp. 13-18°C. Germination takes 12-18 days approx. Transplant seedlings when large enough to handle to 8cm pots and grow on. Acclimatise and plant out after danger of frost has passed. Directly sow 1mm deep into prepared soil which has been raked to a fine tilth with 30cm spacing.
Growing Instructions
Prefers a moist, well-drained, fertile soil. Full sun is preferred for best flowering. Drought tolerant but a moist soil will offer improved flowering.
