When to Transplant Daylilies

Daylilies are versatile perennial flowers that are considered hardy and easy to grow. Available in colors such as yellow, orange, red, purple and pink, daylilies can provide a splash of color in a flowerbed or garden. Because they can grow in many types of soil, tolerate dry spells and resist common garden pests and diseases, they are sometimes called the perfect perennial. In cases when daylilies are no longer thriving, some of the plants can be transplanted to another area to perk them back up.

When To Transplant

• If you notice that your daylily garden has grown too thick and the flowers are no longer thriving, transplanting the plants will allow them to thrive again. Daylilies are hardy enough that they can tolerate being divided and transplanted at any time in the growing season. However, many gardeners prefer to transplant them in the early spring or late fall because it allows the plants plenty of time to become established before blooming again.

Preparation

• Once you decide to transplant some of your daylilies, you’ll need to prepare for the move. The first step will be removing any loose soil from the area by gently brushing it away. Next, take a sharp knife or trowel and cut into the earth to separate the plants from one another. Depending on the root system, you may even be able to use your hands to separate the plants. Make sure to divide the plants evenly so each has a suitable root system that will allow it to continue to grow.

Transplanting

• When you are moving daylilies to a new flowerbed, make sure you choose a site that gets at least 6 hours of sunlight each day. Full sun is best, but light shade will be tolerated. Before moving the plants, dig a hole that is large enough to encompass the entire root ball. Be sure the new location has enough space for the roots to spread out. Once the roots are in place, slowly start to fill in the hole with dirt, patting it down occasionally to fill in any air pockets. After the plant is in place, thoroughly water the plant so the roots can begin to take hold. Use enough water that it will seep down at least 8 inches.
