From Ground: Begin by watering the robin's Plantain plant thoroughly to make the soil easier to work with. Then, carefully dig around the plant with a shovel, keeping a distance to avoid damaging the roots. Try to keep as much of the root system intact as possible. Slowly lift the plant out of the ground, shaking off excess soil.
From Pot: First, water the robin's Plantain plant to moisten the soil. Gently tilt the pot on its side and perform a slight pulling and twisting motion on the plant’s base. The plant should slide out, preserving the root ball. If resistance is felt, you can run a knife between the pot and soil to ease it out.
From Seedling Tray: Water the tray and lightly press the soil around the robin's Plantain seedlings to loosen it. Gently hold the seedling by its leaves (not the stem) and pull up with a slight twist. Use a dibber or pencil to help push seedlings out from the bottom if required.
