Storing geraniums for winter is super easy — you just put them in a cardboard box or a paper bag and close the top. Here are some tips to improve their survival: Keep your geraniums in a cool, dry location, at about 50 to 60 degrees F. Check for mold about once a month and remove dried leaves from the bag or box.
Should you cut back geraniums for winter?
After a perennial geranium has spent the season in bloom and begins to die back, you’ll want to prune it. This keeps the plant dormant for the winter and also helps it store energy for spring. Depending on your zone, this might need to happen anywhere from August to late October.
What is the lowest temperature that geraniums can tolerate?
During winter, geraniums grow best with night temperatures of 50° to 60°F (10° to 16°C) but will survive if they drop to 32°F (0°C) and/or rise above 80°F (27°C), as long as they are kept relatively dry. When new growth appears in the spring, cut off all the old leaves.
Can I keep geraniums in pots over winter?
Geraniums can be overwintered indoors by taking cuttings, potting up individual plants or storing bare-root plants in a cool, dry location. Make sure to do one or all of these things before the first frost.
