From Ground: Initially, water the formosan sweetgum plant to moisten the soil. After that, using a shovel or spade, dig a wide trench around the plant. The goal here is to keep as much of the plant's root ball intact as possible. Work the spade under the root ball to gradually lift the plant from its original site.
From Pot: Start by watering the formosan sweetgum plant to dampen the potting mix, which will make it easier to remove the plant. Tilt the pot sideways, then support the main stem in one hand and use the other hand to gently pull the pot away. If the plant doesn't slide out, you may need to tap the bottom of the pot to release it.
From Seedling Tray: If the formosan sweetgum plant is a seedling, water the tray first. Then, gently hold the seedling by its true leaves— not the stem— and use a fork or dibber to loosen the soil. Gradually lift the seedling, ensuring you retain as much of the root system as possible.
