From Ground: First, water the mock lime plant well so that the soil around the roots becomes damp, which makes it easier to remove. Use a spade to dig a wide circle all the way around the plant, being careful not to damage the roots. Then, gently lift the plant from the ground with its root ball intact.
From Pot: Similarly, water the mock lime plant in its pot. Gently tip the pot to the side and ease the plant out. If it's stuck, try tapping the bottom of the pot or gently sliding a knife around the edge.
From Seedling Tray: Water the seedlings to ease their removal. Lift each seedling by the leaves rather than the stem, as it could easily get damaged. Gently tease the roots free if they’ve grown into neighboring cells.
