Gerainium plants - care?
Thanks for writing. Geraniums are pretty easy --- grow them in full sun and well-drained soil. The plants do better being too dry than too wet, so let the top inch or so of the soil dry out before you water the plant again. You can feed it with any general-purpose garden fertilizer; just be sure to follow the directions on the packaging carefully. That said, if you have a good potting mix, you may not need to fertilize your geraniums at all to get them to produce lots of blooms.
Once the flowers fade, remove the stem they're on to stop the geranium from putting energy into making seeds and to help the plant stay looking better.
