Ask Mr. Smarty Plants

The best time to transplant mustang grape (Vitis mustangensis) and most other woody plants is during the dormant season from late November to late January. Select small, young plants as much as possible, since they will adjust better to being transplanted. Select new transplant sites that feature similar conditions to the ones in which the plants are presently growing, paying particular attention to light and moisture level.

Prepare the plants' roots by root pruning now. The purpose of root pruning is to circumscribe your root ball and prompt the formation of callus tissue, from which new roots will emerge. To do this, use a sharp shooter shovel or sharp spade to dig down around the plants in a circle as broad and deep as your root ball will be. The callus tissue will form between now and November.

When transplanting time arrives, dig the new hole first so the selected plants won't be exposed too long. Get as large a root ball as possible, and use a planting container or canvas/burlap cloth to transport it in.

Once the plant is set in the new hole and packed in, trim off 1/3 of the top growth to reduce transpiration in the spring. Water regularly for at least the first year to help the plant get established in its new site.
