From Ground: First, water the torrey's rush 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: Begin by watering the torrey's rush thoroughly to allow the roots to slide out more easily. Turn the pot sideways, support the plant with one hand and gently tap the bottom of the pot to ease the plant out. If the plant is stubborn, roll the pot on its side, applying gentle pressure with your hands to loosen the root ball.
From Seedling Tray: Water the seedlings to moisten the soil. Use a hand trowel or a dibbler to gently lift each torrey's rush out of its cell by loosening the surrounding soil and carefully pulling the plant out, making sure to support the root ball.
