Even those with little space or inhospitable climates can grow citrus by planting in a container. Citrus trees that grow well in containers include limes, lemons, and kumquats. A big advantage of planting in containers is that they can be pulled in for protection from a freeze.
Citrus containers can be plastic, metal, or wood—the material doesn't matter, as long as the container is large enough for the plant and has adequate drainage. A pot that is about fifteen inches wide and deep is a good size to start a young tree.
Most well-drained potting soils are fine for citrus, although some prefer more acidic soil. Citrus trees grow best in full sun. Water trees only when the top inch or two of the soil is dry to the touch, then water thoroughly. Your tree will require very little pruning except to remove stray branches or lower limbs.
