From Ground: First, water the sunshine dahlia to dampen the soil, making it easier to dig. Next, 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, gently lifting the plant from its original location, taking great care to avoid damaging the roots.
From Pot: Water the sunshine dahlia thoroughly the day before transplanting. Hold the base of the stem and gently tip the pot upside down, tapping the sides to loosen the plant. Carefully slide the plant out, supporting the root ball with your other hand.
From Seedling Tray: Water the seedlings lightly to ease removal. Using a hand trowel or an old spoon, gently lift each seedling from the tray by its leaves or base, being careful not to damage the delicate roots.
