From Ground: First, water the aegean dock plant to dampen the soil. This will make it easier to remove the plant without damaging the roots. Use a shovel to dig a wide circle around the plant, taking care not to injure the root ball. Gently lift the plant from the ground, making sure most of the roots remain in the soil clump.
From Pot: Water the aegean dock plant thoroughly before starting. Turn the pot to its side and gently tap the bottom to loosen the plant. You may need to roll the pot on its side to ease the roots out. Once loose, carefully pull the aegean dock plant out by the base, supporting the root ball.
From Seedling Tray: If transplanting seedlings, water them first to minimize root disturbance. Use a hand trowel or a dibber to ease the seedling out. Handle the seedling by the leaves rather than the stem to avoid damage.
