Can I bring some of my favourite geraniums inside to overwinter?

Yes!

Unlike most annual bedding plants, geraniums are easily propagated by cuttings. Kept on a warm windowsill over winter, or in a tray with a T 5 fl orescent light, your cuttings will quickly develop roots and leaves.

How to do it:

Select healthy, squat and fat shoots. Remove them from the parent plant by cutting immediately above a bud.

  • Remove flower buds and lower leaves from the bottom half of each cutting and cut the stem just below a node, where there is a concentration of the plant’s own hormones.
  • Dip the base of each cutting in a small amount of rooting hormone, such as Power Root, to stimulate root growth.
  • Fill pots with Coco coir or a good potting soil mixed with sand or vermiculite to aid drainage. Insert 2 or 3 cuttings around the edge of each pot. Water the soil or coco and stand pots in a well-lit position, indoors. Do not cover the pots.
  • After a few weeks, a corky callus will develop over the cut end of the stem. A good root system will have developed within 6-8 weeks.
  • In March or April, knock each cutting out of the pot and transplant into individual pots. Keep well-watered and plant out in spring.
