From Ground: If the winter aconite plant is in the ground, first dampen the soil around the plant using a watering can. Once the soil is wet, dig a trench around the plant with your shovel or spade. Be sure to keep the root ball intact. Carefully loosen the soil underneath the root ball, and then lift the plant from the ground.
From Pot: If the winter aconite is planted in a pot, first water the plant to moisten the soil. Then, tilt the pot sideways, and gently pull the plant out, keeping the root ball intact. If necessary, use a knife to help loosen the edges.
From Seedling Tray: If you're dealing with seedlings in a tray, first wet the soil lightly. Then, carefully lift the seedling using a small spoon or fork, making sure not to damage the roots.
