From Ground: Start by
watering the ground around the field maple, this will dampen the soil making it easier to dig up. Then, use your shovel to dig a wide trench around the field maple ensuring the root ball remains intact. Carefully work your spade under the root ball to loosen the soil then gently lift the field maple up from its original location.
From Pot: Water the field maple while it is still in the pot, this will help to make the soil compact and prevent it from crumbling while removing the plant. Turn the pot sideways and hold the field maple close to its base, shaking lightly to encourage the plant and its root ball to slide out. If the field maple doesn’t slide out easily, tap the bottom of the pot gently.
From Seedling Tray: Use the trowel to carefully scoop out each seedling, making sure to keep as much soil around the roots as possible. Handle the seedlings by their leaves to avoid damaging the tender stems.
