When to Sow

Sow April to May and plant out May to June.

Where to Sow Sunflower Seeds

Sow seed thinly in drills 45cm (18”) apart in well cultivated soil raked to a fine tilth. Germination usually takes 15-21 days. For earlier sowings, sow indoors, individually in 7.5cm (3”) pots at 20-25°C. When well grown, gradually acclimatise to outdoor conditions before planting out after all risk of frost has passed in a well drained soil in full sun.
