my zinnias are fading in color--is it because of the non stop rain we have had for the last several weeks? could it be now the rains have stopped and the long 90+ days are here--they are full sun plants but maybe the heat? or do i need to feed them?
ok--thanks--good to know it might not be something i did wrong! when you say fade with age i guess you mean fade right before they are ready to dead head--i guess i had some strange idea that zinnias keep their blooms--i guess what they do is keep blooming!!
Yes, they continue to bloom if the fading blooms are removed. If left on the plant, the plant senses that seeds are forming and it's life-cycle is completing, so it prepares to die. If fading blooms are removed, the plant never senses that seeds are forming, so it continues to reproduce by blooming again.
No, seeds will not form on the blooms you remove, those blooms will simply dry up and die. Even if you keep them in water, they won't mature. They have to be attached to the plant. If seeds have already formed, and are almost mature, you can pick the blooms and keep them in water for a little while to help them along...this situation would be in the instance of a frost being forecast and you almost had ripe seeds.
