Lilies are gorgeous, colorful flowers that come in numerous varieties and colors. They thrive in warm weather and bloom during the summer months, making them a popular choice for gardens and landscapes. However, not all lily plants can survive the harsh and cold winters.

If you have planted lilies in your garden and want to keep them alive until next season, you need to take proper precautions to overwinter them effectively. In this article, we will discuss how to overwinter lily bulbs and ensure your plants are healthy and blooming next season.

1. Choose the Right Variety

Lilies come in various types that have different hardiness levels. Bulb plants such as Asiatic, Oriental, and Trumpet lilies are hardy and can tolerate the cold winter months. On the other hand, non-bulb lilies like Calla and Daylilies cannot withstand the severe winter season.

Therefore, it is essential to choose the right variety that can survive the winter season, depending on the location where you live.

2. Determine the Ideal Planting Time

Lilies should be planted in fall, before the ground freezes. This timing helps the lilies establish their roots before the winter season sets in. If the ground in your location does not freeze, you can still plant the lilies in mid to late fall.

However, if you have planted your lilies in spring or summer, you need to dig them up before the first frost and store them indoors for the winter season.

3. Cut back and wait for Foliage to Die

After the lilies have bloomed, it is essential to cut back the foliage to about two inches from the ground level. During this time, the plant will start to absorb the nutrients into the bulbs to prepare them for winter dormancy.

Wait until the foliage has yellowed and died off before you dig up and store the bulbs indoors. This timing ensures the bulbs receive enough nutrients.

4. Dig Them Up

Once the foliage has died off, it is time to dig up the bulbs for winter storage. Use a fork to loosen the soil around the bulbs, carefully lifting them out of the ground. Make sure to remove any dead or damaged bulbs from the plant.

5. Clean the Bulbs

Before storing the bulbs, it is essential to clean them. Gently remove any excess soil and debris from the bulbs without damaging them. You can also use a fungicide to prevent any fungal diseases during storage.

6. Store in a Cool and Dry Place

Lily bulbs should be stored in a cool and dry place to prevent them from drying out or rotting. An ideal temperature for storage is between 35-50 degrees Fahrenheit.

You can store them in a cardboard box with peat moss, sand or dry vermiculite. Make sure to label the box with the variety and the date when they were dug up for reference.

7. Monitor the Bulbs

Periodically monitor the lily bulbs during storage to ensure they are not drying out or developing any disease. If you notice any signs of decay or rot, remove the affected bulbs immediately to prevent spreading to the other bulbs.

In conclusion, overwintering lily bulbs requires proper planning, timing, and storage. By following the above tips, you can ensure your lily bulbs are healthy and blooming come next season. So, get ready to enjoy your beautiful lilies next summer!
