Hiya i was just wondering if anyone can give me some advice on what to do with sunflower heads as they start to die off as i heard somewhere that you can dry them out then freeze the seeds for planting next year but i have no idea how to go about it and would be grateful for any advice as the one my daughter grew from school this year was amazing and would love to try to grow more next year.
thanks for any help i can get
Fiona
