From Ground: Begin by
watering the sugar maple plant at the base to saturate the soil. Use a spade to dig a wide trench around the plant, making sure not to damage the rootball. Carefully slide the spade under the root ball, lift it from the ground, then place it on a tarp or large cloth for transport.
From Pot: Water the plant and let it drain. Lay the pot on its side and gently coax out the sugar maple by squeezing the pot or tapping it gently against the ground. Always handle the plant by its rootball, never by the stem or trunk.
From Seedling Tray: Water the trays and gently loosen the soil around each sugar maple seedling with a small spade or hand tool. Then, lift the seedling by the leaves, not the stem, as it's the toughest part of the plant at this stage.
