What should I feed my geraniums so that all the flowers in each blossom bloom at once?

I find that miracle grow helps a little but I still have the problem with the whole flower not blooming at once, having dead mixed in, while others are till budding on the same flower.

Reply:You cannot feed them anything to do that. Plants produce flowers in stages. If you had them all completely bloom at once then there would be no blooms for a long time. Enjoy the fact that the will give color to your garden all summer long. Did you also know they do even better in some light partial shade.

Reply:First of all you should dead head the old blooms that have shriveled. Then you can buy a spray at Home Depot called Bloom forcer that will help the geranium bloom better. It's tough to get all the the flowers to Bloom at once, but this is the best solution.
