The Best Time to Transplant Clematis

Transplant Timing

• Transplant anytime between the late fall and early spring as long as the plant is not actively growing. Late fall and winter plantings are difficult in most climates because of frozen soil. Transplanting in the spring, before the first leaves emerge, is often the best time.

Digging the Clematis

• Dig up as much of the root as possible. This can include a root ball up to 18 inches across. The fewer roots broken during the transplanting process means there will be less stress on the plant in its new location. Wrap the root in a bag or tarp for short local moves and keep the soil around the root moist. Purchased plants, especially mail order, may arrive as bare-root plants but should also be dormant. Plant these as soon as possible to avoid drying out the root.

Planting the Clematis

• Dig a hole between 18 and 24 inches deep for most clematis transplants. Ultimately, the top of the root ball should be about 5 inches below ground. If the root ball measures 13 inches from top to bottom, for example, an 18-inch hole would suffice. Fill in the void around the clematis root with a 50 percent mixture of soil and compost. Potted clematis often have a small stake as part of the plant presentation. Leave the stake in place with the soil while transplanting. Lean the stake towards the shrub or trellis you want the clematis to climb.

Keeping it Growing

• Clematis require a continuous water supply through the growing season. Keep the ground moist and cool with mulch or a ground cover plant along with adequate water if natural rains are not sufficient. Adding rotted manure or compost to the top of the ground twice a year improves soil fertility.
