From Ground: Initially, water the cedar of lebanon so that the soil around roots is moist, which makes it easier to remove. Then, proceed by digging a circle around the plant, ensuring enough space to include all its roots. Avoid damaging the roots, and gradually work your shovel under the root ball. Once done, lift the plant carefully.
From Pot: Water the plant sufficiently. Turn the pot sideways, hold the cedar of lebanon close to base, and gently pull and twist the plant out of its pot. If it's stuck, you might need to tap the pot's rim on a hard surface to loosen the root ball.
From Seedling Tray: Water the cedar of lebanon before attempting to remove it. Using a dibble or other blunt tool, gently lift the plant out by going in from the sides, ensuring to lift the entire root ball and minimizing contact with the stem or roots.
