Tropical Horticulture: Lecture 32 1
Tropical Horticulture: Lecture 32 Lecture 32 Citrus Citrus: Citrus spp., Rutaceae Citrus are subtropical, evergreen plants originating in southeast Asia and the Malay archipelago but the precise origins are obscure. There are about 1600 species in the subfamily Aurantioideae. The tribe Citreae has 13 genera, most of which are graft and cross compatible with the genus Citrus. There are some tropical species (pomelo). All Citrus combined are the most important fruit crop next to grape. 1 Tropical Horticulture: Lecture 32 The common features are a superior ovary on a raised disc, transparent (pellucid) dots on leaves, and the presence of aromatic oils in leaves and fruits. Citrus has increased in importance in the United States with the development of frozen concentrate which is much superior to canned citrus juice. Per-capita consumption in the US is extremely high. Citrus mitis (calamondin), a miniature orange, is widely grown as an ornamental house pot plant. History Citrus is first mentioned in Chinese literature in 2200 BCE. First citrus in Europe seems to have been the citron, a fruit which has religious significance in Jewish festivals. Mentioned in 310 BCE by Theophrastus. Lemons and limes and sour orange may have been mutations of the citron. The Romans grew sour orange and lemons in 50–100 CE; the first mention of sweet orange in Europe was made in 1400. Columbus brought citrus on his second voyage in 1493 and the first plantation started in Haiti. In 1565 the first citrus was brought to the US in Saint Augustine. 2 Tropical Horticulture: Lecture 32 Taxonomy Citrus classification based on morphology of mature fruit (e.g. -

Tangerines, Mandarins, Satsumas, and Tangelos
Tangerines, Mandarins, Satsumas, and Tangelos Category: Semi-evergreen Hardiness: Damage will occur when temperatures drop below the low 20’s Fruit Family: Citrus Light: Full sun to half day sun Size: 10’H x 10’W; may be pruned to desired HxW Soil: Well-drained Planting: Plant after danger of frost has passed, mid to late March The name “tangerine” derives from one variety that was imported to Europe from Tangiers. There are many named varieties of what citrus growers call “mandarins” because of their Asian origins. One of these, the “Satsuma”, is an heirloom Japanese mandarin that is both delicious and especially adapted to Southeast Texas. It has been part of Gulf Coast Citrus history for a century. There are many named varieties of Satsumas. Mandarins are mostly orange-fleshed, juicy, highly productive, very easy to care for, long-lived, easily peeled and segmented or juiced. Few fruits can match the mandarin. Satsumas are seedless or close to seedless. They are all of outstanding quality and differ little among themselves except for when they ripen. Buy early, mid and late season varieties to have months of ripe fruit harvests from September to April. Care of Mandarins and related fruits Planting: Newly purchased citrus have probably not been hardened off to tolerate our winter weather. Keep your citrus in the container until late March, or until all danger of freeze has passed. Trees can be kept outside in a sunny area on mild days and nights, but move them into the shelter of the garage or house if frost is predicted. -

We are a 501C3 organization under IRS statutes. Monies collected from this sale supports the B.E.E.S. educational and demonstration gardens located at the end of CR 171. One of this years’ major projects is to build walkways which meet handicap standards and for our senior citizens. The gardens are open on Tuesdays and Fri- days to the public. Special topic programs are offered on Saturdays for public attendance and are advertised in local newspapers and radio. The gardens include eating fruits (berries, fruit, etc.), herb garden, tropicals, veggies, rose garden, two greenhouses other demo/experimental plants. The contents of this brochure utilized multiple resources from leading agricultural universities, Texas and other state and national organizations. Fruit plants are selected on basis of Master Gardener feedback in our county as well as neighbor counties. Past demand & interviews of folks after each years’ February sale help us select new varieties and determine plant volume each year at the sale. BCMG makes genuine efforts to provide the public with information on plants offered. Other than assuring the public that we use only licensed nurseries, BCMG cannot assure success. -
