What is the difference between citrus vs. fruit trees? Citrus trees are fruit trees, but fruit trees are not citrus. That is, the fruit is the seed bearing part of the tree that is usually edible, colorful and fragrant. It is produced from a floral ovary after fertilization. Citrus refers to the shrubs or trees of the family Rutaceae.
None of the citrus tree varieties enjoy wet roots. All require excellent drainage and, ideally, sandy loam soil, although citrus can be grown in clay soils if irrigation is managed well. While citrus trees tolerate light shade, they will be more productive when grown in full sun. Young trees should have suckers pruned out. Mature trees need little to no pruning except to remove diseases or damaged limbs.
