About this item
- COSMOS MANDARIN SEEDS: A half hardy annual, flowers the same year as sown. Radiant orange blooms on rounded, compact plants. Flowering over a long season, for beds and borders.
- SOW: February to May, FLOWERS: June to October, SPACING: 30cm, HEIGHT: 45cm, SUNLIGHT: Full Sun, SEEDS: 30 Approx.
- SOW INDOORS: For surest results, 0.5cm deep, in trays of compost. Water well and place in a warm position, a temperature of 15-20℃ is ideal. Keep moist. Seedlings usually appear in 14-21 days. Transplant seedlings 5cm 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 25cm apart, when frosts are over.
- SOW OUTDOORS: For ease, where they are to flower, 1.5cm deep into finely prepared soil which has already been watered. Thin seedlings to 25cm apart. Water well until plants are established. Remove dead flowers to prolong flowering season.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
