Pest & Disease Information
Sunflowers are phototropic (they follow the light). This can cause neck bending. This may also be due to improper stage at harvest, flower dehydration or improper sanitation. This can be avoided by maintaining optimal temperatures during transport and storage and adhering to best practices with cleanliness and hydration/feeding. Leaf yellowing could be due to improper stage of harvest, improper cultural practice or non optimal storage and handling conditions. Remove nets prior to processing. Avoid handling the flower by the head to avoid creasing and bruising to the petals. Sunflowers can drink a lot of water. Be sure to use a vase that holds plenty of water and can support the weight of the flowers.
