From Ground: First, water the dianthus collinus 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: Water the dianthus collinus plant thoroughly one day before transplanting. Gently tap the sides of the pot to loosen the soil. Carefully tilt the pot and slide the plant out, holding the base of the stem and supporting the root ball.
From Seedling Tray: Ensure the seedlings are well-watered before removal. Gently lift the seedlings from the tray using a hand trowel or small scoop, making sure to support the root ball and retain as much soil as possible around the roots.
