I love geraniums and have six. I am struggling however. The leaves go yellow, then brown, then fall off, they grow leggy and just don't look that happy.
I have tried putting them in a sunny window and they struggle. I've tried putting them in a less directly sunny window and they struggle. I water about twice a week. I turn their pots. I sometimes repot them. I allow them to dry out between watering. These are all the combinations of care and still they struggle. They are kept indoors mainly with the odd day outside. I did plant some outside once and their leaves went red and they died ? too sunny.
Does anybody have a definitive bomb proof way of caring for these plants?
