Citrus Trees

Citrus is thought to have developed in Southeast Asia in about 4000 BC. Citrus probably entered Europe after the fall of the Roman Empire. Citrus fruits were first brought to America by the Spanish and the Portuguese. The fact that citrus trees are evergreen and cannot tolerate freezing dictated that the warm climates of Florida and California became the leading citrus producing states in the Unites States. Citrus fruits belong to the ‘Rutaceae’ family. Citrus fruits are fragrant, with or without seeds depending on the variety, and contain significant amounts of vitamin C, pectin, and fiber. They are fat free, sodium free, and cholesterol free.

The dwarf citrus trees offered by Nature Hills may also be grown inside. Dwarf citrus trees in containers can be successfully grown throughout the United States. Citrus like 8 to 12 hours of sunlight a day. Full-spectrum fluorescent grow lights are the best supplement for inside growth. They will tolerate less light in the winter than in the spring and summer. For container soil, use a light, well draining commercial soil mix. Do not put gravel in the bottom of the pot. Place the container on pebbles in a saucer or other surface that will allow air and water flow. Water them every 5 to 7 days with ¼ to ½ gallon of water. Do not keep them standing in water. The soil should be moist, not soggy. Citrus foliage benefits from being sprayed or misted with water, especially in winter months when the humidity might be low. A humidifier would also help keep the leaves lush and healthy.
