How to Overwinter Geraniums
If you have enjoyed your beautiful geraniums all summer, you can continue to enjoy bright blooms all winter with a few simple steps. You can then replant them in the summer and enjoy your geraniums all over again. Read on to learn how.
Things You’ll Need
- Clean and disinfected knife
- Rooting media
- Good light
- It is best to use a new cutting from your plant for fresh growth. This reduces the risk of carrying over health problems. Take the cuttings at the end of September or early August.
- Disinfect the knife you will use to take the cutting with a solution of one part bleach to eight parts water. Disinfect the knife between cuttings. This prevents the spread of fungus or bacteria.
- Remove the excess leaves and stipules on the stem. The stipule is a little outgrowth from the base of the stem.
- Stick the cutting in rooting media. Peat pellets, coarse sand or perlite work well, too.
- Water and mist the cuttings. Keep the cutting in indirect light while rooting and move to full sun when it blooms.
- Give the cutting a gentle tug to check the roots. The cutting should start to root in about two weeks.
- Pot the cuttings about four weeks after they were cut.
- You can also overwinter the whole plant. Cut it back hard and re-pot it in fresh soil. Keep the plant in the sunniest spot possible. Water only once a week and don’t feed during the winter. Don’t start feeding until spring. Cut back spindly growth around March and your plant will be full in May.
