I grow a conservatory full of pelargoniums.....don't know why cos they aren't a real favourite of mine. lots of colour but no form.
watering? I watered this morning. not too much but they were dry. their weight is a give away on this too. doesn't get too cold here although temps will be around 2 or 3 tonight and the conservatory is double glazed but unheated. In a warm room they will need regular watering.
My regime is to cut hard back in September. Every flower and most every leaf. Stems cut hard. Cuttings then available. I watered well then. Regrowth is rapid but compact and the result is tidy mounds of plants ready to burst into flower early in spring.
I also overwinter pelargoniums in a cold greenhouse. ..even a few outside. Depending on the winter they often survive.
