How to perk up overwintered geraniums?
I brought in about a dozen geraniums (annual pelargoniums) last fall, mostly because I have a really hard time letting go of the growing season. About half are unusually colored ivy geraniums. They have done pretty well all winter and most bloomed sporadically. A bit leggy, though.
If I want to "refresh" these for this summer, what should I do? Cut back hard, then repot? Wait a bit before repotting? Just add fertilizer instead of repotting?
