From Ground: Start by watering the rock elm plant thoroughly a day before the planned move to dampen the soil, helping preserve the root ball during the move. Dig a trench around the plant using a shovel or spade, making sure you are far enough from the base to avoid cutting into the root system. Once you encircle the plant, carefully work the spade under the root ball, gently loosen the soil, and lift it out from its original location. Wrap the root ball in burlap or a plastic sheet to protect it during the move.
From Pot: Water the plant the day before the move. To remove the plant, tip the pot to the side delicately, and tap the edge lightly on a solid surface like a bench or the ground to loosen the root ball. Gently grasp the base of the plant and ease it out while making sure to avoid pulling on the stem or trunk.
From Seedling Tray: Water the seedlings adequately and let them rest. To remove the seedlings, squeeze the bottom of each cell, pushing the root ball upward than usual. Gently grasp the seedling by the leaves, not the stem, and lift it out carefully.
