Sowing Guide

Early Sowing/Module Sowing

Sow one sunflower seed onto the surface of moist compost in 7 - 10 cm pots.
Cover the seeds with 5mm of compost.
Place in a propagator or if preferred cover with a clear polythene bag and seal. Germinate at the temperature suggested above.
Once the seeds start to germinate remove from the propagator or bag and place in a well lit area with a reduced temperature. Protect from frost.
When all risk of frost has passed and the sunflowers are growing strong and have a strong root system, plant outdoors.
Harden off over 7 - 10 days before planting out.

Direct Sowing

Sow direct from mid April to mid May 40 - 50 cm apart in a well prepared seed bed where the flowers are to grow.
Sow at the depth suggested above.
Keep the soil moist however do not overwater.

Growing On

Water the young plants regularly until established.
The helianthus plants when 50 - 60 cm tall will benefit from being fed with some liquid fertilizer. However avoid over feeding as this can lead to weakened stems.
Tall varieties will need supports adding to help prevent the flowers falling over.
Water established plants regularly in dry weather and especially if growing in containers.


For a continuous succession of sunflowers sow the seeds every 2 - 3 weeks from February to mid May.
