Citrus trees require a great deal of sunlight so shaded locations are generally not suitable for planting citrus trees. From the standpoint of soil, the ideal is well-drained sandy loam. However, these trees will grow in a variety of soils providing that drainage is good. Check with your local tree care specialist to see what kinds of fertilizers, if any, citrus trees require for the soils in your area. If the occasional period of freezing weather is expected in your region, choose a site on the protected south side of a building.
