As a gardening and landscaping expert, I can confidently say that you do not necessarily have to dig up daylilies in the fall. Daylilies are hardy perennials that can withstand the winter months without needing to be dug up and stored indoors. However, there are a few situations where digging up daylilies in the fall might be necessary or beneficial.
1. Transplanting: If you want to move your daylilies to a different location in your garden, fall is a great time to do so. The ideal time for transplanting daylilies is after the final bloom in the summer, as this allows them to establish new roots before the onset of winter. However, they can be divided and transplanted until the end of autumn.
2. Overcrowding: Daylilies are known for their ability to multiply and spread, forming dense clumps over time. If your daylilies have become overcrowded and are not blooming as profusely as they used to, dividing them in the fall can rejuvenate them. By digging up the clumps and separating the individual plants, you can create more space for each daylily to thrive and produce abundant blooms.
3. Pests and Diseases: In some cases, daylilies may be affected by pests or diseases that can be better managed by digging them up and inspecting their roots in the fall. For instance, if you notice signs of crown rot or root knot nematodes, it may be necessary to dig up the plants, remove any affected portions, and replant them in fresh soil to prevent the spread of the issue.
4. Garden Renovation: If you are planning a major garden renovation or redesign, it may be necessary to dig up daylilies in the fall to clear the area and make way for other plants or features. This can be an opportunity to divide and transplant the daylilies to other parts of your garden or share them with friends and neighbors.
In any of these situations, it is important to handle the daylilies with care when digging them up. Use a sharp spade or garden fork to gently lift the clumps from the ground, making sure to not damage the roots. Once the clumps are lifted, shake off any excess soil and carefully separate the individual plants by pulling them apart or using a clean, sharp knife. Replant the divisions at the same depth they were previously growing, ensuring they are well-watered and mulched to retain moisture.
While daylilies do not necessarily need to be dug up in the fall, there are certain circumstances where it may be beneficial or necessary. Whether you are transplanting, dividing overcrowded clumps, managing pests or diseases, or renovating your garden, fall can be a suitable time to dig up and replant daylilies to ensure their continued health and beauty.
