How to Winter Geraniums: Essential Tips for Successful Caring

How to Winter Geraniums?

To winter geraniums, there are a few methods to choose from.

One option is to take stem cuttings from the plant, dip the base in rooting hormone, and plant them in a pot with vermiculite or perlite and sphagnum peat moss.

After they have rooted, transfer each cutting into its own pot and keep them in a sunny window or under artificial lighting until spring.

Another method is to dig up the geraniums and place them in large pots indoors.

Water them every two weeks, prune in March, and they should develop into healthy plants.

Lastly, you can dig up the geraniums before the first fall frost, remove soil from the roots, and either store them in a paper sack in a cool, dry place or hang them upside down in the same conditions.

In March, remove dead material, prune back to live stem tissue, and pot them.

Once they have developed, they can be planted outdoors after the last frost.

Key Points:

  • Take stem cuttings, root them, and plant in pots with vermiculite or perlite and sphagnum peat moss
  • Transfer rooted cuttings to individual pots and keep them in a sunny window or under artificial lighting until spring
  • Dig up geraniums and place them in large pots indoors, watering every two weeks and pruning in March
  • Dig up geraniums before first fall frost, remove soil from roots, and store in a cool, dry place or hang upside down
  • In March, remove dead material, prune back to live stem tissue, and pot them
  • Once developed, plant geraniums outdoors after the last frost
