Why are my sunflower seeds empty?
Another common reason why you may not see any seeds on the sunflower is simply lack of pollination. … It might be there are limited bees and insects in the area, and not enough to pollinate all the seeds. Ideally, the sunflowers need to be within 300 feet of a beehive to have enough chance of bee pollination.
When should I cut off my sunflower heads?
Harvest when seeds are plump and developed. Harvest when flower petals begin to dry out and fall off. Harvest when the back of flower turns from green to yellow (if you are cutting the stem off to dry). Harvest when the back of the flower is brown (if you are letting seeds dry with the stem intact).
Will sunflowers regrow after cutting?
A 4- to 6-inch-long stem with mature leaves and no buds or flowers will root best and produce a shapelier plant. Sever the cutting where it attaches to the main stem using very sharp scissors or a utility knife, and then cut off the lowest set of leaves to expose the root-producing nodes.
Should I deadhead sunflowers?
As a general rule, deadhead flowers when they start to fade, or when they are damaged and no longer attractive, but do so before they produce seeds. When a sunflower’s flower head stops looking as vibrant as it once did or when its yellow ray petals have fallen off, select it for deadheading.
