Geraniums will do that when started in February or early March. No, there is nothing you should do except maybe turn the plant 1/4 turn every other day to ensure all parts get equal sun. Water to drainage when it needs it, dump the excess and let the foliage grow at will.
It will be a happier plant when the warm weather arrives.
Put it outside during the warm parts of the day, back indoors at night, back outdoors for longer periods each day until you feel it can stay outside when all danger of frost is past.

This isn't a potted plant. Planted outside early last summer.

LOL, how do you turn 'Rozanne' 1/4 turn every other day?Sorry, goren, I guess you didn't realize miclino is talking about a hardy perennial geranium in his/her garden. Don't worry miclino. 'Rozanne' should be just fine left on her own. If the weather gets cold again and the leaves are damaged, new ones will soon grow again.
