01Grown for seed and oil

Beyond a cheerful garden feature, sunflower heads produce a substantial crop of seed for eating, oil pressing, or poultry feed — a genuinely useful homestead crop.

02Planting

Method
Direct sow once frost risk has passed.
Soil
Well-drained, tolerates a range of soils.
Timing
Sow in spring.

03Growing care

  • Water regularly while establishing, then reduce — deep roots find their own moisture.
  • Stake very tall varieties in windy positions.
  • Protect developing seed heads from birds if you want to harvest seed yourself.
  • Support heavy heads if needed as seed fills.

04Problems

  • Birds — will strip a ripening head quickly; net if harvesting for yourself.
  • Powdery mildew — late-season on leaves; largely cosmetic.
  • Stem lodging — wind damage on tall varieties; stake if exposed.
  • Few significant pests otherwise — a generally easy crop.

05Harvest & storage

Signs
Back of the head turns brown/yellow, seeds are plump and firm.
Method
Cut the whole head, hang to finish drying.
Curing
Dry heads fully before rubbing out seed.
Storage
Airtight, cool, dark — keeps many months.
