From Ground: Begin by watering the black alpine sedge plant so the soil is moist and easier to work with. Use a spade to dig a wide trench around the plant, making sure to keep clear of the root ball. Gently work your spade under the roots to lift the whole plant out. Ensure the integrity of the root ball is maintained.
From Pot: Lightly water the black alpine sedge plant to moisten the soil. Carefully tip the plant and pot sideways, tapping the sides to loosen the soil. Hold the plant at its base and gently ease it out of the pot. If the plant is root-bound, gently tease the roots apart before transplanting.
From Seedling Tray: Water the seedlings to make extraction easier. Using a trowel, carefully lift the seedling by scooping under the roots. Aim to keep as much of the root and soil intact as possible to reduce transplant shock.
