From Ground: Water the happy plant generously to dampen the soil. Once done, dig a wide circle around the plant with your garden spade, ensuring the root ball remains intact. Carefully work the spade under the root ball to lift the plant and check there are no broken roots.
From Pot: Water the happy plant and wait a few minutes until the water drains through the pot. With your gloves on, tilt the pot sideways and gently squeeze or tap it to loosen the plant. When the happy plant starts to move, pull it out carefully ensuring minimal damage to the roots.
From Seedling Tray: Water the happy plant seedlings. Let the water soak the soil, then with your garden trowel, loosen the soil around each seedling. Gently grip the stem of the seedling between your fingers and lift it out, being careful not to damage the roots or leaves.
