From Ground: Start by watering the soil around the hop sedge to make it easier to remove. Use the spade or shovel to dig around the plant, ensuring to keep the root ball intact. Carefully lift the plant from the ground, trying not to damage the root system.
From Pot: If the hop sedge is growing in a pot, water the plant first to make the root ball cohesive. Tip the pot upside down while supporting the plant at the base. Gently pull the pot away from the root ball, if it's stuck, you might need to slide a knife around the edge of the pot.
From Seedling Tray: Water the seedlings first. Then gently lift the hop sedge from its cell by pushing up from the bottom. Avoid pulling on the stem to prevent damage.
