From Ground: First, water the dahlia 'Zorro' plant to dampen the soil. Then, dig a wide trench around the plant using a shovel or spade, ensuring the plant's root ball remains intact. Carefully work the spade under the root ball to lift the plant from its original location.
From Pot: Water the dahlia 'Zorro' plant thoroughly. Gently turn the pot on its side and tap the bottom to loosen the root ball. Slide the plant out of the pot, taking care not to break or damage the roots.
From Seedling Tray: Water the seedlings well. Carefully use a garden fork or your fingers to loosen the soil around the seedling. Support the base of the seedling while you lift it, ensuring the roots remain intact.
