Question

Using liquid fertilizer, how often should I fertilize my geraniums planted outside?

R.E.: HOW TO USE.

Answer 2

No offense to anyone, but Winkie offers a valid suggestion.

   Your issue in part, involves soil composition, rainfall, or watering, how much SUN the plants get, and certainly any ZONE you may be in. If flowers need fertilizer it often means they aren't getting enough of something from the soil, or in the attention given them. Flowers, in seasonal confines, usually do well enough naturally.

   You should also check packaging for instructions regarding keeping any chemicals OFF of leaves and flower blooms, and ask at the garden center.
