How to Grow & Harvest Sunflowers

 

When to Plant

Start your sunflowers indoors about 4 weeks prior to the last frost.  Sow them 2-3" beneath the surface of the soil. Keep your seeds well watered while you wait for them to germinate.  Transplant outdoors once the threat of frost has passed. This will ensure the largest possible yield of seeds at harvesting time.  

 

How to Plant

Sunflowers can grow to heights of 8 feet or more and provide you with a large quantity of delicious seeds. Choose an area that gets plenty of sun, a minimum of 6-8 hours will be needed.  Amend the soil with rich compost and organic fertilizers. 

 

When to Harvest

Harvest the seed heads in late summer or early fall once the back of the flower head has began to die and turn yellow. This means that the seeds are ready. Simply collect the seed heads and dry them in a well-aerated, dry location.
