From Ground: First, water narrow small-reed to dampen the soil, which will make digging easier and help reduce root damage. Then, insert a garden fork into the soil around narrow small-reed, approximately 12-18 inches from the base to avoid severing roots. Carefully lift the root ball, keeping as much soil intact as possible with the roots.
From Pot: Water narrow small-reed adequately before removing it from the pot to help ease the transition. Gently tap the sides and bottom of the pot to loosen the soil. Tip the pot sideways and support the plant by the root ball. Ease narrow small-reed out of the pot, ensuring not to pull the plant by the stems.
From Seedling Tray: Water the seedlings to ensure the soil is moist. Use a spoon or a small trowel to gently scoop out narrow small-reed from its compartment, taking extra care not to damage the delicate roots. Support the seedling by the root ball rather than the stems or leaves.
