When to Transplant Fruit Trees?

Q. With this unusually mild LV winter, when is the best time to transplant dwarf grapefruit trees?

A. By transplant I take it to mean you are moving a grapefruit from one location to another location. Planting or transplanting can be done now. You will have more success if the tree has not been in the ground more than three years. You will have even more success if the tree has been watered by drip irrigation in a fairly small basin or area next to the tree. You will have even more success if the tree was root pruned last fall around mid to late September.

trees from the orchard as we learn about them and
then move on to those varieties we have not explored.
Root systems can get large quickly and make it no longer
feasible to relocate older fruit trees to new areas after
about three years in the ground

            Root pruning just means you went around the entire tree with a shovel and severed the roots in the approximate location where you are planning to dig and transport it. Given all that, prepare your hole for planting first before you move the tree. Dig deep enough to accommodate the root ball but not much deeper.

            It is more important to dig it wide than it is to dig it deep. Get your soil amended and add some phosphorus to the soil. Move your tree as quickly as possible to its new location and try to orient it in a similar orientation, north to south, as it was in the old location.

            Backfill around the tree. During planting, run a hose in the hole at the same time you backfill to remove air pockets. Drive a stake next to the tree and into the bottom of the hole into solid ground. This stake will immobilize the roots if tied to the tree tightly.

            I usually use rebar pounded into the soil next to the tree after it has been planted. I wrap the tree and rebar together with green nursery tape to immobilize roots. This leaves the top to move in the wind.

            The trees should be planted the same depth as it was when it was removed from the soil. No deeper and no shallower. If you have rabbits, protect it with one inch chicken wire after planting. Mulch the soil around the tree with wood mulch keeping the mulch away from the trunk a foot. After one season of growth, remove the stake.
