How to Save Ranunculus Corms // Digging, Dividing, and Storing Ranunculus Corms

Learn how to dig, divide, and store ranunculus corms in this video tutorial. Generally, gardeners in zone 6b and colder should dig and store the corms. Although the leaves can handle frost, the corms and roots cannot experience a freeze/thaw cycle. Additionally, the corms may rot if they sit in wet, cold soil over the winter. Once the plants turn brown dig up the corms and cut off the dead foliage. Place the corms in a seed tray or crate and allow them to dry for a few days. If ranunculus corms are moist or wet during storage, they may succumb to mold or rot. Once the corms are dry place them into mesh bags. Label the bags with the variety name and store them in a dry, dark, cool location until the following year. A basement is the ideal storage location. However, any room that doesn't experience freezing temperatures or excessive heat and humidity will be fine. In the late winter, bring the corms out of storage and start the pre-sprouting process again!
