Why do sunflowers droop?

When a sunflowers head has completely bloomed, when it's been pollinated and becomes heavy with seeds, then it's perfectly normal for the head to bend over and droop down.

When should I cut down my sunflowers?

Harvest of annual sunflowers does not begin until the petals wilt and begin to fall. You can prevent seed loss to birds, squirrels and deer by covering the blossoms with paper bags at that point. After the seed shells fatten up but before they dry out, cut the sunflower stalks about 12 to 18 inches below the flower.

What do you call flowers that come back every year?

Can sunflowers get too much sun?

Sunflowers need full sun, which means at least six hours of unfiltered sunlight every day.

Have to agree with Sue, most sunflowers are once and done. If they're even remotely rebloomers, they need to be "deadheaded", that is, spent flowers have to be removed to continue the bloom and not allow seedheads to form. Most flowering plants need to be dead headed to produce more flowers.
