how long do blooms last on sunflowers
Here's my tip: Make sure they are in FULL sun. They grow best, meaning tallest, when they are basking in the sun most of the day. My experience was that the blooms on annual sunflowers last only about 2 weeks before they droop. If you want continuous blooms, plant seeds every 2 weeks. Also, the blue jays, cardinals and other birds in my back yard loved the sunflowers and it was fun to watch them dive and feed.
