Geraniums Indoors Looking Great

I have six pots of geraniums (Pelargonium) sitting in a south facing window that, today, with the sun shining on them, look really fantastic. After a way too long winter, these beautiful plants are making me feel like spring is on the way. All of these plants are from one pot given to me by my mother-in-law many years ago before she passed away. She started this plant from seed and it produces a lovely pink flower. Every year in the late summer I bring the pots indoors. I cut the stalks severely, let the cuttings suffer for a week or so, and then re-pot them. In winter they sit inside and endure the cold dark days of that chilly season. This year, just after Christmas, they started to look spindly and weak. So I cut them all back very severely, to the point where I feared I may have cut too much. But after a couple weeks they started showing new sprouts. Now they are looking bright green and bushy and they have a couple flowers starting to emerge. Around Mother's Day they will go back outside to their customary spots on the semi-shady front porch and on the mostly sunny back steps. I am looking forward to the joy they always bring.
