From Ground: First, you have to use a garden fork to gently loosen the soil around the yant. Make sure to do this gently to avoid damaging the root system. By doing this, you will ease the removal of the plant. Next, use a shovel to dig a wide circle around the yant. Make sure the circle is large enough to avoid damaging any roots. Once you have a large enough circle, you can use the shovel to lift the plant. Be careful when lifting as yant's leaves can be spiny and sharp.
From Pot: First, you should water your potted yant well to help ease the transition and removal from the pot. Next, tip the pot on its side and lightly tap it to loosen the plant. Then, gently pull it out from the pot. Make sure to get as much of the root system as possible.
From Seedling Tray: If you're removing a yant seedling from a tray, start by watering the tray. Then, gently grasp the seedling near the base, and carefully lift it. Use your other hand to support the root ball.
