From Ground: Start by watering your arrow-head plant to make the soil and roots easier to work with. Using your shovel or spade, carefully start to dig around the plant, making sure you dig deep enough to avoid damaging the root system. Once you have loosened up the soil, lift the plant and its root ball carefully and place it in your large container or burlap.
From Pot: Water your arrow-head plant. Then, turn the pot sideways, hold the plant gently by its base, and try to slide it out. You might need to tap the base of the pot to help it loosen up. Make sure you avoid pulling the plant as it can damage the roots.
From Seedling Tray: If your arrow-head plant is a seedling in a tray, water it first. Hold the base of the plant and use a thin stick or popsicle stick to push up from the bottom, lifting the seedling out of the tray. Try to handle it by the leaves rather than the stem, which is more delicate.
