From Ground: First, water the southern watergrass 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 southern watergrass plant thoroughly to make the soil easier to work with. Gently tap the pot to loosen the soil. Turn the pot over, supporting the southern watergrass plant with one hand, and gently slide the plant out by squeezing the pot or tapping the bottom.
From Seedling Tray: Water the southern watergrass seedlings to avoid disturbing the roots. Use a garden trowel or a small spoon to carefully lift each seedling out, ensuring you capture as much root as possible.
