Can You Transplant Pines?

When?

Pine trees should not be transplanted at any time close to a time of frost. Iowa State University Extension and Outreach and North Dakota State University recommend transplanting pines in late summer to early fall so that roots have time to establish in their new spot before the first frost. My Minnesota Woods also attributes this time of year as when soil and moisture conditions are ideal for vigorous root growth. It is still possible to transplant pines in late spring if necessary.

The chances of a successful transplant will increase if you plant your pine tree in conditions compatible with its natural habitat. Gather clues from the area you are removing the pine from, such as available sunlight, soil type and moisture. According to Clemson University Cooperative Extension, most pine species grow best in well-drained soil rich in nutrients. Some types of pines, however, have their own specific growing conditions. For example, Virginia pines grow well in dry, clay soils, poor in nutrients where they are exposed to full sun; longleaf pines grow best in acidic, sandy soils poor in nutrients. If you are able to identify the pine species you wish to transplant, replant it in a place that fits its needs.

When removing the tree from its original site, cut around the tree with a sharp spade to create an adequate root ball to prevent the loss of major roots. The size of the root ball is dependent on the size of the tree, states Clemson University Cooperative Extension's article "Transplanting Established Trees and Shrubs." For example, if the pine tree's branch spread is 2 feet, dig at a depth of 9 inches and at least 6 inches on either side of the trunk. Plant the transplant as soon as possible. If you have to transport the transplant over a large distance, wrap the root ball in moist burlap or peat moss to prevent shock or root loss. Dig a hole at least twice as wide as the root ball; the depth should be the same as the hole dug where the pine tree was removed. Replace the soil dug in the same order as it was found in the ground and ensure that the transplant's roots and base are snug in the ground. Water the transplant immediately after planting.

Nurseries accustomed to raising and selling tree transplants practice root pruning one to two years ahead of time to avoid "transplant shock." You can do the same thing, if you are planning to eventually transplant a pine in your backyard. Clemson University Cooperative Extension recommends root pruning in spring if the tree will be transplanted in the fall and vice versa. North Dakota State University recommends a two-year process, which involves digging a trench around half of the root ball in three separate segments the first year and digging a trench in the three remaining segments the second year; trenches are then refilled with soil and watered.
