Understanding Geraniums: The Basics
Before we jump in, here’s something interesting – what we commonly call geraniums actually belong to two different groups:

We’ll talk about both types in this article because, well, they’re both beautiful and interesting.

Handy tip: How to overwinter geraniums
Before the first frost, cut your geraniums back by about 15 centimetres. Move them to a light but cool place away from frosts, most likely indoors, ideally where the temperature is between 5 and 10 degrees Celsius. In winter, water only when the soil has dried out, very rarely. In March, take the geraniums out of their winter spot and prune back any new growth. Repot your geraniums in fresh soil. Check the roots and generously prune any dry or rotten parts. Water the plants and then put the pots somewhere warm (18 degrees Celsius) with lots of light. The geraniums will grow new roots and leaves there. After the last frost, they can go outside. We’ll now put the spotlight on some of the more commonly-known varieties of geraniums.
