I do not have a problem starting geraniums from seed but I have plant lights. I start geranium seeds very early so that by the end of May (when we plant in VT) the plants are good sized. I start them in a square seed flat and then when they have two sets of leaves move them to six packs. I think more people should try geranium seed. I love to have different flowers in my pots and these Summertime Mix were beautiful, trailing, pastel and white flowers. Delicate but lovely. I mixed in begonias too!
