To help your geraniums survive the winter, follow these steps:

  1. Prune Your Plants: Before the first frosts appear, prune your geraniums using pruning shears or scissors. Remove faded flowers, damaged stems, and dead leaves.
  2. For Geraniums Grown in Soil:
    • Carefully pull the plants out of the ground, avoiding damage to the roots.
    • Cut the branches above the collar and trim the roots.
    • Prune the stems to 10-15 centimeters.
    • Choose to either plant the geraniums in planters or hang them on a rope in an optimal environment for growth.
  3. For Potted Geraniums:
    • Remove wilted, yellow, or dead stems, cutting them back to 10-15 centimeters.
    • Eliminate parasites and diseased parts.
    • Take healthy stem cuttings for future growth.
    • Place the containers in a frost-free area with ample light and a temperature between 8 and 15°C, such as a veranda, garden shed, or garage with a window.
  4. Winter Care:
    • Avoid watering your geraniums during the winter, especially during frosty periods, to prevent root rot.
    • Ensure the leaves do not wilt, but do not overwater.
  5. Post-Winter Care:
    • As winter ends and vegetation resumes, gradually reintroduce water and light.
    • Repot geraniums in fresh soil and gradually transition them from shade to partial shade to full sun.
    • Eventually, plant them outdoors in suitable soil to prepare for blooming in warmer weather.

By following these steps, you can effectively overwinter your geraniums and ensure they thrive when spring arrives.
