From Ground: Start by watering the reed mannagrass plant to dampen the soil, making it easier for extraction. Outline a circle around the plant, leaving enough space to include the full root system. Use a garden fork or spade to dig around this circle, carefully working it underneath the root ball. Gradually lever the tool to lift the plant out.
From Pot: Water the plant lightly to moisten the soil. Tip the pot gently to its side and pull the plant out, holding it at the base as close to the soil as possible. Try not to pull by the stems.
From Seedling Tray: Make sure the reed mannagrass seedlings are well-watered prior to transplanting. Use a dibber or something similar to lever the seedlings out, including as much root as possible.
