From Ground: First, water the dahlia 'Vancouver' 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: Gently tip the pot on its side and slide the dahlia 'Vancouver' plant out. Tap the sides and bottom of the pot if needed to loosen the root ball. Be cautious not to damage the roots as you remove the plant.
From Seedling Tray: Moisten the soil in the seedling tray to make it easier to lift the seedlings. Use a trowel or your fingers to carefully lift each dahlia 'Vancouver' plant, ensuring you do not damage the delicate roots.
