Citrus in Pots

Well, you can, quite easily, even without a garden. Just plant a citrus tree in a large terra-cotta pot. (Some cultivars actually prefer containers, and will remain compact and flower better when their roots are constricted.) Set the pot in an area that receives plenty of sunshine, such as a terrace or greenhouse, for approximately six hours a day. During the winter, bring the tree indoors -- these plants need warm temperatures (above 55 degrees). It should take the plant about seven to eight months to mature. Martha has a variety of potted citrus, such as Meyer lemons, 'Nagami' kumquats, and 'Bear's Seedless' limes, accenting her gardens. Today, she demonstrates how to pot a dwarf blood-orange tree sent to her by Four Winds Growers in Fremont, California.
The terra-cotta pot should have a drainage hole and be at least 8 inches wider and deeper than the plant's root ball. Place shards in the bottom of the container.
Fill the pot about 1/4 full with a light, well-drained soil mix. Take the tree out of its plastic, tease out its roots, and place it in the container. Be sure the graft -- the knobby part of the stem near the root -- is above the pot's rim.
Backfill with soil mix. Water well about twice a week, and place in a sunny spot. Fertilize twice a month with a balanced fertilizer. Every few years, remove the plant, prune its roots by about a third, and replenish old soil mix.
