Citron (Citrus medica) grows up to 3 meters high by 2 meters wide. It can be cultivated in a pot and kept indoors. The plant blooms from March to October. The white or purple flowers are very odorant. Citron has yellow fruit with a rough and bumpy surface, thick and fleshy skin, little juice, and sweet flavor.
Scientific Name: Citrus medica
Common Name: Citron
How to grow and maintain Citron:
Citron require 8-12 hours of daylight every day to be healthy and productive. A south or southwest facing window with unobstructed light is for the most part perfect. Citrus trees don’t go dormant in winter and will tolerate slightly lower light conditions during this period of slower growth. If space has less than 5 hours per day of direct, full sun, you may require additional lighting such as Grow Bulbs.
Soils Tolerates an extensive variety of soils; in any case, does not stand waterlogged soil, and grow best in freely draining soils, pH 5–8.
Water as expected to keep soil moist, not wet. Generally 1/4 – 1/2 gallon of water each 5-7 days indoors is satisfactory. Make sure the base of the pot is levated above standing drainage water. A moisture tester can be an excellent tool to help determine when roots are in need of a drink.
citrus trees are heavy nitrogen feeders, ensure your compost contains more nitrogen (N) than phosphorous (P) and potassium (K), for example, Miracle Gro 24-8-16. Avoid fertilizing from September to January indoors, but once light levels increase in February you can fertilize once every two weeks. If placing plants outdoors in the summer, plants should be fertilized until the end of August.
Harvest those fruits when they are around five inches in length and still somewhat green if you wish to candy the
peels. Wait for them to turn yellow and more fragrant on the off chance that you need to make pomanders.
Pests and diseases:
The most widely recognized bugs on citrus trees in the Midwest are brown soft scale and two-spotted spider mite, and occasionally aphids, mealybugs, or whiteflies. Washing the foliage periodically can help deter these pests. Insecticidal soap or synthetic insecticides can be used against all of these, although physically wiping the scales off the leaves and branches may also be needed as any sprays will only kill the crawler stage of that insect. Light horticultural oil may also be effective against scales. With all of these pests, multiple applications may be required to achieve control.
