From Ground: Firstly, water the bell Pepper plant adequately to moisten the soil, this makes removal easier. Using the shovel, dig around the plant, keeping in mind to stay several inches away from the base to avoid damaging the root system. After you've made a full circle around the plant, carefully deepen the circle until you could work the shovel beneath the root ball and lift the plant smoothly.
From Pot: Begin by watering the bell Pepper in its pot. Tip the pot on its side and gently pull the base of the plant, if the plant doesn’t come out easily, tap the sides and bottom of the pot to loosen. Avoid pulling the plant forcefully as it may damage the plant's stem and roots.
From Seedling Tray: To remove bell Pepper from a seed tray, water the tray first. Then, gently hold the seedling by its leaves (avoid holding from stem) and push the base of the seedling upwards, again, be gentle to not harm the plant.
