From Ground: First, water the spiny rest-harrow to dampen the soil, making it easier to dig. Use a shovel or spade to create a wide circumference around the plant, being careful not to damage the root ball. Gently slide the shovel beneath the root ball to lift the spiny rest-harrow out of the ground.
From Pot: Water the spiny rest-harrow in its pot first to make the soil more pliable. Tip the pot to the side and gently tap or squeeze it to loosen the plant from its container. Support the base of the plant and carefully slide it out while preserving the root ball's integrity.
From Seedling Tray: Water the tray to soften the soil, which will make it easier to remove the seedling. Use a spoon or a dibber to gently lift the individual spiny rest-harrow seedling, keeping the roots and surrounding soil undisturbed.
