The Q&A Archives: Selecting Dwarf Orange Trees For Indoor Growing,w And Sw Exposure

Question: Can you please recommend two dwarf orange trees for growing in containers indoors in a very sunny room with west and southwest picture windows?

Answer: In cold winter areas citrus trees can be grown indoors from September through April and then taken outdoors a placed in a sunny spot. Indoors, citrus trees need average warmth, freedom from drafts, ample water, and well draining soil. You may need to supplement natural light with fluorescent or gro-lites especially made for plants. Turn the light on for

12-14 hours each day and turn it off at night. Citrus trees

need ample moisture, so water often enough to keep the soil

moist but not soggy, and feed in the spring and summer

months with a diluted liquid fertilizer, especially if the leaves are yellowish instead of glossy deep green. Watch out for scale, aphids and mites, and use insecticidal soap or light horticultural oil according to label instructions if they do show up.

Be sure to give your trees a gradual transition from indoors to outdoors, and vice versa, so they have time to adjust to the changes in the environment.

Sweet oranges aren't likely to develop on indoor trees, but of the citrus that do well inside, you can choose from Improved Meyer or Ponderosa lemon, Bearss lime, and Rangpur sour orange.
