Planting & Harvesting

Sow & Grow

Sow indoors, for surest results, 0.5cm (¼in) deep, in trays of compost. Water well and place in a warm position, a temperature of 15-20°C (60-68°F) is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant seedlings 5cm (2in) apart to other trays when large enough to handle. (Always handle by a leaf, never by the stem.) Grow on in cooler, but not cold conditions. Gradually accustom young plants to outside conditions (avoid frosts), before planting out 30cm (1ft) apart, when frosts are over. Or sow outdoors for ease, where they are to flower, 1.5cm (½in) deep into finely prepared soil which has already been watered. Thin seedlings to 30cm (1ft) apart. Water well until plants are established.

Hint's & Tips

Remove dead heads regularly to prolong the flowering season. This dwarf variety is an excellent choice for exposed locations.
