Economic Information
The tangerine, often grouped with other mandarin varieties, holds a significant position in the global fruit market. Worldwide production of mandarins (including tangerines, clementines, and satsumas) easily reaches into the tens of millions of metric tons annually, making it one of the most widely cultivated citrus fruits after oranges. China is by far the largest producer, accounting for a substantial portion of global output, followed by countries like Spain, Turkey, Morocco, Brazil, and the United States, particularly Florida and California.
The market value of tangerines is substantial, driven by their popularity as a fresh eating fruit, their use in juices, and their contribution to the essential oil industry for flavorings and fragrances. Their ease of peeling, sweet flavor, and often seedless nature make them a consumer favorite, especially during the fall and winter months. For farmers, tangerine cultivation represents a vital source of income, supporting rural economies and providing employment in harvesting, processing, and distribution. The demand for convenient, healthy snacks continues to fuel the economic importance of this versatile citrus fruit.
Growing Guide
Soil Preparation
Like any good citrus, tangerines are particular about their feet! They absolutely thrive in well-draining soil. If your soil is heavy clay, you'll want to amend it generously with organic matter like compost, aged manure, or peat moss. This helps break up the clay and improves drainage. On the flip side, if you have very sandy soil, organic matter will help it retain nutrients and moisture. Aim for a slightly acidic to neutral pH, ideally between 6.0 and 7.0. A soil test is your best friend here; it'll tell you exactly what you're working with and what amendments are needed.
Planting
Choose a spot that gets full sun β at least 6-8 hours of direct sunlight daily is ideal. Tangerines are sun-lovers! Plant in spring after the danger of frost has passed. Dig a hole twice as wide as the root ball and just as deep. Carefully remove the tree from its container, loosen any circling roots, and place it in the hole so that the top of the root ball is level with or slightly above the surrounding soil. This is crucial for drainage and preventing rot. Backfill with your amended soil, gently tamp down to remove air pockets, and water thoroughly. If you're planting multiple trees, space them 10-15 feet apart to allow for mature growth and good air circulation.
Watering
Consistent watering is key, especially for young trees and during dry spells. Don't just give them a little sip; tangerines prefer deep, infrequent watering. This encourages roots to grow deeper, making the tree more resilient. Check the soil moisture by sticking your finger about 2-3 inches deep. If it feels dry, it's time to water. Reduce watering in winter when the tree is less active. Remember, soggy soil is a death sentence for citrus roots, so good drainage is paramount.
Fertilizing
Tangerines are hungry plants! They benefit from a regular feeding schedule, typically 3-4 times a year, starting in late winter/early spring, then early summer, and again in late summer/early fall. Use a balanced citrus-specific fertilizer that includes micronutrients like iron, zinc, and manganese. Follow the package directions carefully. For organic growers, compost, fish emulsion, and kelp meal are excellent choices to nourish your trees and improve soil health.
Pruning
Pruning isn't just about making the tree look pretty; it's vital for health and productivity. For young trees, focus on establishing a strong scaffold of branches. Remove any suckers that sprout from the rootstock below the graft union β these will steal energy from your desired fruit. As the tree matures, prune to remove dead, diseased, or crossing branches. Thin out the canopy slightly to improve air circulation and allow sunlight to reach the inner branches, which helps with fruit production and reduces disease risk. The best time to prune is after harvest, before new growth begins in spring.
Harvesting
This is the moment you've been waiting for! Tangerines are usually ready for harvest from late fall through winter, depending on the variety. Look for a vibrant orange color and a slight give when gently squeezed. Taste is the ultimate test β pick one and try it! Don't rely solely on color, as some varieties can be ripe before they're fully orange. To harvest, use clean pruning shears or clippers to snip the fruit from the branch, leaving a small piece of stem attached. Avoid pulling them off, as this can damage the fruit or the branch. Store harvested tangerines in a cool, dry place or in the refrigerator for longer storage.
Varieties
Dancy

Pests & Diseases
Common Pests
Citrus Aphids
Small, soft-bodied insects that cluster on new growth, sucking sap and causing leaves to curl and distort. They also excrete honeydew, leading to sooty mold.
Management: Organically, spray with insecticidal soap or neem oil, or introduce beneficial insects like ladybugs. Conventionally, systemic insecticides can be used, but always check local regulations and harvest intervals.
Citrus Leafminer
The larvae of this tiny moth tunnel within young leaves, creating silvery, serpentine trails and causing leaf distortion and curling.
Management: Organically, prune off heavily infested leaves, use neem oil on new flushes of growth, or encourage parasitic wasps. Conventionally, specific insecticides can target the larval stage, but timing is critical.
Scale Insects
Tiny, immobile insects that attach to stems, leaves, and fruit, sucking sap and weakening the tree. They are often covered by a protective waxy shell and also produce honeydew.
Management: Organically, hand-scrape small infestations, use horticultural oil (dormant or summer weight), or release predatory beetles. Conventionally, systemic insecticides or targeted oil sprays can be effective.
Spider Mites
Tiny arachnids that cause yellow stippling on leaves and, in severe cases, fine webbing. They thrive in hot, dry conditions.
Management: Organically, spray with insecticidal soap or horticultural oil, and ensure adequate watering. Conventionally, miticides can be applied, but rotation is important to prevent resistance.
Common Diseases
Citrus Canker
Symptoms: Raised, tan to brown lesions with a watery margin and a yellow halo on leaves, stems, and fruit. Severe infections cause defoliation and premature fruit drop.
Treatment: Prevention is key: use disease-free nursery stock and prune out infected branches immediately. Copper-based fungicides can help manage spread, but strict quarantine measures are often enforced in affected areas.
Phytophthora Root Rot (Gummosis)
Symptoms: Yellowing leaves, wilting, poor growth, and dieback. At the base of the trunk, you might see dark, water-soaked lesions that ooze a gummy substance (gummosis).
Treatment: Improve drainage, avoid overwatering, and ensure the root crown is not buried. Plant on mounds in heavy soil. Fungicide drenches can be used as a treatment, but prevention through good cultural practices is most effective.
Citrus Greening Disease (Huanglongbing - HLB)
Symptoms: Yellow shoots, blotchy mottling on leaves that crosses veins (unlike nutrient deficiencies), small, lopsided, bitter-tasting fruit that remains green at the bottom. It's a devastating disease.
Treatment: There is no cure. Infected trees must be removed to prevent spread. The disease is spread by the Asian citrus psyllid, so controlling this pest is crucial for prevention. Use certified disease-free nursery stock.
Sooty Mold
Symptoms: A black, powdery coating on leaves, stems, and fruit. This is a fungus that grows on the honeydew excreted by sap-sucking insects (aphids, scale, whiteflies).
Treatment: Treat the underlying pest infestation. Once the honeydew source is gone, the sooty mold will eventually flake off or can be washed off with a strong stream of water or insecticidal soap.

History
Ah, the humble tangerine! A true gem in the citrus family, its story is as rich and vibrant as its fruit. Our journey with the tangerine begins deep in the ancient lands of Southeast Asia, particularly southern China. For thousands of years, long before it ever graced a European or American table, this delightful fruit was cultivated and cherished by Asian farmers. It's not a wild fruit in the same way some other plants are; rather, itβs believed to be a hybrid, possibly a cross between a mandarin and a pomelo, honed over centuries by careful selection and cultivation.
The tangerine, often used interchangeably with 'mandarin orange,' holds deep cultural significance, especially in China. During the Chinese New Year, these bright, auspicious fruits are exchanged as gifts and displayed prominently, symbolizing good fortune, prosperity, and a long life. The word for 'tangerine' in Chinese sounds similar to 'gold,' further cementing its association with wealth and good luck. Imagine generations of families celebrating with these cheerful fruits, their sweet aroma filling homes and temples.
It wasn't until the early 19th century that the tangerine made its grand voyage westward. The first significant introduction to the Western world is often attributed to Italy, arriving around 1828. From there, it quickly captured the hearts (and palates) of Europeans. But perhaps the most enduring anecdote is how it got its common English name: 'tangerine.' This name comes from Tangier, a major port city in Morocco, from where the first shipments of these easy-to-peel oranges were sent to Europe and eventually to North America in the mid-19th century. So, every time you peel a tangerine, you're enjoying a fruit with a passport full of stamps and a history steeped in tradition and trade!
