Here's how to winter chrysanthemums in pots:
1. Protect from Frost:
* Bring Indoors: The most reliable way to protect chrysanthemums from frost is to bring them indoors. Choose a bright, cool location (around 45-55°F or 7-13°C) that receives some sunlight. A sunroom or a garage with a window is ideal. Avoid drafty areas.
* Cold Frame: If you have a cold frame, it can provide a good buffer against frost. Place the potted chrysanthemums inside the frame and cover with a frost blanket or clear plastic when temperatures drop.
2. Cut Back and Prune:
* After First Frost: Once the first frost has hit, prune back the stems to about 6 inches above the soil line. This will help prevent disease and encourage new growth in the spring.
* Deadhead: Remove any dead or wilting flowers and stems throughout the winter months.
3. Water Sparingly:
* Dormancy: Chrysanthemums go dormant during the winter. Water only when the soil is completely dry to the touch. Overwatering can lead to root rot.
* Check for Drainage: Ensure the pots have good drainage to prevent water from sitting around the roots.
4. Fertilize Carefully:
* Limited Feeding: Do not fertilize during the winter.
* Spring: You can start fertilizing lightly in the spring when new growth appears.
5. Spring Revival:
* Gradually Harden Off: In spring, when the risk of frost has passed, gradually acclimate the chrysanthemums to outdoor conditions by bringing them outside for increasing periods of time.
* Repotting: If needed, you can repot the chrysanthemums into larger pots in the spring. Use a good-quality potting mix.
Additional Tips:
* Mulch: A layer of mulch around the base of the pots can help insulate the roots and prevent frost damage.
* Location: Choose a location that receives full sun in the spring and summer.
* Disease Prevention: Regularly inspect your chrysanthemums for any signs of disease and treat accordingly.
By following these steps, you can give your chrysanthemums the best chance of surviving the winter and blooming beautifully the following year.
