Pelargonium is one of the most forgiving plants I know of. They will take off with top growth when they are ready. I have four which I plant this time of year in a commercial garden in down town Calistoga. A large expanse of asphalt parking lot is directly to the south and it is so hot I only work there first thing in the morning. Every year about the first of December I dig them up root prune enough to fit in a gallon pot with room for some potting soil. I cut the top down to practically nothing and put them in a cold frame over the winter. Now they are over two feet tall and the pots are bulging with roots. I dig new holes in the same locations water them in and we are good till digging time. They don't know their life is limited. Al
