When you are planting a plant or tree, loosen the root ball. This will help the plant from being stunted.
Dig the hole for the plant twice as wide as the pot it came in, and the same depth as the pot.
When placing the plant in the hole, use the same dirt that you dug out to make the hole, to fill back in around the plant.
If you use rich potting soil, the plant’s root will have a hard time growing past the rich soil to the normal soil.
