Storing geraniums for winter is super easy — you just put them in a cardboard box or a paper bag and close the top.

Is it worth keeping geraniums over winter?
Geraniums only need to be kept frost free, so are very economical to overwinter in the greenhouse. However, we do recommend using a heater to ensure temperatures stay above freezing. If your heater has a thermostat, set it at 5°C or 41°F. If the stems get frosted then the plant will die and not recover!

How far should I cut back my geraniums?

How many years do geraniums last?
The average life expectancy of a geranium is about two years, and although they will last much longer than that, they tend to get woody and the blooms diminish. Luckily, propagation is easy with geraniums. Simply take four-inch stem tip cuttings with at least two pairs of healthy leaves.
