From Ground: Firstly, water the chittagong wood plant well enough to make the process of uprooting easier and less damaging to the plant. Next, dig a wide radius around the plant with a shovel or hand trowel, leaving enough space so the plant's roots remain undamaged. The depth of the radius should coincide with the general spherical area that the entire root system likely occupies. When you're sure you've dug around the entire root area, use the shovel to carefully push underneath the root ball, and gently lift the plant out of the ground. Try to keep the root ball intact as much as possible.
From Pot: If your chittagong wood is coming out of a pot, watering the plant a few hours ahead is recommended. Turn the pot on its side, roll it gently if needed to loosen the soil and roots. This will help the plant slide out of the pot. Make sure you handle the root ball gently to avoid breakage.
From Seedling Tray: To remove a chittagong wood seedling from a tray, you should wet the tray first. Next, use a spoon or a small tool to carefully leverage the seedling out, starting with the edges and making sure to avoid damaging the roots.
