The Best Time to Transplant Perennials Such as Hostas & Daylilies

When to Transplant

• The best time to transplant perennials is in the fall, before the first frost but after the blooming season is over. At this time, perennials are using less water, since they are not producing any new growth. This lessens the chance of damage from lack of water during transplanting. You can also transplant in the spring, after the ground has thawed but before the first buds appear. This gives the plants time to get re-established in their new locations before the heat and drought conditions of summer kick in.

Preparing for Transplanting

• To help your plants thrive after transplanting, take some preparatory steps beforehand. First dig the hole in the new area of your garden, so that as soon as you dig up the plant you can place it in the new hole immediately. Also, trim away any spent leaves, stems or flowers, as well as any dead or damaged material. The less plant material, the less water the plant will need to recover. If you are transplanting in fall, remove the top 1 to 2 inches of the plant's new growth to facilitate water retention.

Transplanting

• For most flowers, transplanting is as simple as digging up the plot of ground that holds the roots with a spade or shovel and moving the whole thing to a new location. If your plant has become overgrown or if you wish to replicate the plant, you can remove up to half of the plant's body while it is out of the ground. Known as dividing, this is a great method of propagation and can help to create a healthier plant, since it will not be overburdened by extra material. Bury the roots you keep in the new location under at least 2 inches of soil.

After Transplanting Care

• Watering is the most important aspect of caring for a perennial after transplanting. Until the roots become established in the new soil, they will be limited in regards to the amount of water they can take up. Therefore, water the plant anytime the soil right around the base feels dry on the top 2 to 3 inches. This way, the roots have an easier time getting water to the rest of the plant, reducing the chance of long-term damage.
