Once you find the type of orange tree you want, it is time to make sure you have the right location for it. Orange trees grow best in full sun, but they can also grow well in partial shade. They also like soil that is arid, gritty, and drains well. To prepare the site, clear out all trash — old roots, twigs, stones — and be sure to weed the area and rake the soil. You should also make sure the area you have chosen will be large enough to accommodate a mature orange tree.
