From Ground: First, water the japanese pepper to soften the soil. Then, using a spade or shovel, carefully dig a wide perimeter around it to ensure the roots are not damaged. Gently pry underneath to free the roots and lift the plant out. Ensure the root ball is kept intact.
From a Pot: Begin by watering the japanese pepper to ease extraction. Turn the pot on its side and gently slide the plant out. Avoid tugging or pulling as this can damage the roots. If the plant is root-bound, meaning the roots are tightly wound around the edge of the pot, you can gently loosen them before transplanting.
From a Seedling Tray: If you've started your japanese pepper in a seedling tray, ensure it has developed roots that are strong enough to transplant. Use a spoon or a small tool to carefully lift the seedling, making sure you keep as much of the root system intact as possible.
