From Ground: First, water the white horehound plant lightly to slightly loosen the soil making it easier to remove. Then, using a trowel or spade, carefully dig around the plant ensuring the root ball is not damaged. Lift the plant gently from its original location keeping the root ball intact.
From Pot: Water the white horehound moderately. Then, turn the pot sideways while gently pulling the plant out holding at its base. If it resists, run a knife or trowel around the inside edge of the pot to loosen the root ball.
From Seedling Tray: Water the white horehound lightly. Carefully remove the seedling by lifting from its base. Make sure not to pull the plant as it can cause damage to the roots.
