Why do I have brown spots on my geraniums?

Answer by  hibpmgirl (2166)

Over watering most likely. Try letting the dirt around your plant dry up entirely on the surface and a half inch down. THen try watering it sparingly. enough to wet the surface and then let it dry out again. Brown spots can also occur from over exposure to sunlight, kind of like a sunburn for a plant, try giving shade

Geraniums are hard to keep going for a long time try to pick the leaves with the brown on them off and the rest should thrive.

They need to be repotted and given a little feed, though not too much, or they will produce a lot of leaves and not so many flowers.
