Tips & Advice:
Sowing Indoors
Fill a small 6cm pot with seed compost, shake and level firm with the base of another pot. Water well with a fine rose. Sow seeds individually into compost, pushing seeds to 1cm deep. Place in a propagator at 15-20°C or cover pot with cling film and leave in a warm room.
Growing On
When shoots appear, remove cling film. 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. Water well until established.
Sowing Outdoors
Sow seeds in pre-watered soil at a depth of 2cm in their flowering positions. Keep soil moist until seedlings are established. Thin out to 25cm apart.
Special Note
Do not remove spent sunflower heads. They provide attractive autumn seed heads which are great for providing wild birds with a treat.
