From Ground: You'd want to start by watering the indian tobacco plant to dampen the soil. Then, using your shovel or spade, carefully dig a trench around the plant ensuring that the plant's root ball remains intact. Gently work the spade under the root ball to lift the plant from the ground.
From Pot: Begin by watering the indian tobacco, this helps to ease removal. Turn the pot sideways, hold the plant gently and tap the bottom of your pot until the plant slides out. Avoid pulling the plant as it can damage the root ball.
From Seedling Tray: Water the indian tobacco plant first. Using a dibber or a small stick, gently push up under the root ball to lift it out. Be sure to handle the seedlings by their leaves to prevent root damage.
