From Ground: First, water the giant maidenhair fern plant to dampen the soil which will make digging easier. Then, dig a wide trench around the plant using a shovel or spade, ensuring the plant's root ball remains undisturbed. Carefully work the spade under the root ball to lift the plant while preserving the maximum amount of roots.
From Pot: Water the giant maidenhair fern plant well before removing it from the pot. Turn the pot to the side, tap its rim on a hard surface and carefully slide the plant out, ensuring that the root ball remains intact.
From Seedling Tray: Moisten the soil in the tray, then use a spoon or a small spade to lift the giant maidenhair fern seedlings out, ensuring you do not cause any damage to the roots. Handle the seedlings by their leaves to avoid damage.
