Tangerine (Citrus reticulata) is a small thin-skinned variety of orange belonging to the mandarin orange species of the family Rutaceae. The tender, juicy, richly flavored pulp is abundant in vitamin C. Oil extracted from the fragrant skin of the tangerine is a characteristic ingredient in several flavorings and liqueurs.
Tangerine Tree |
The
tangerine tree is smaller than other orange trees. It bears slender twigs
and glossy lance-shaped evergreen leaves. The white five-petalled flowers
are fragrant. The fruit is slightly flattened at either end and has a
loose reddish orange peel and easily separated segments. Some varieties ship
well, and those marketed commercially include Minneola, Orlando, Dancy, and
Seminole. Tangerines have been crossed with grapefruit to
produce tangelos.
Tangerine
skin is so easy to peel; it is like unzipping a zipper on a jacket. The
Tangerine fruit also come in separate sections that are easy to peel apart and
are absolutely delicious. Tangerines have a very short growing season so they
are in great demand when they are available.

Varieties
There
are several different types of tangerines including Clementines, Tangelos, and
Temples.
Clementines: are a
small sweet and seedless variety of tangerines. They are also known as the
Algerian Tangerine. The skin that covers the inner fruit is thinner than what
you will find with regular tangerines. Clementines are known for their sweet
tasting juice and are often used for cooking because of their sweetness. Many
people like to make marmalade from Clementines because of their sweet taste.
Tangelos:
are very interesting, because they are a cross between a pomelo and a
tangerine. The name Tangelo is generated from the combination of the words
pomelo and “tangerine.” At first glance one might mistake a Tangelo for a large
orange but, you can tell the difference between a Tangelo and an orange because
Tangelos have a unique shape, like a bell, while oranges are perfectly round.
Tangelos are also smaller than oranges.
Tangerine Fruit |
Temples:
are also known as the Royal Mandarin. Temples are a hybrid fruit that are the
result of cross breeding an orange and a tangerine. Temples look like a small
orange instead of a large tangerine. They are absolutely delicious because they
are extremely juicy and sweet. Many people think that Temples taste more like
oranges than tangerines. To find out if they taste more like oranges than
tangerines to you, you might want to try them when they are in season, which is
from January to March.
Pruning: The Importance of Pruning in Fruit Trees Management
Ecological Requirements
Tangerines
grow well in areas that don’t have harsh winters and will produce an abundance
of flavorful fruit every year with just a little bit of help. Tangerine is a
seasonal fruit just like oranges and lemons. While a single tree can produce
fruit on its own, planting more than one tangerine cultivar in an area can
increase the yield of tangerines on all the trees. Major
production areas in Kenya are at the Coast, Eastern and Rift Valley
provinces.
Climatic Conditions
Tangerines
are relatively cold-tolerant, making them easier to grow than oranges,
grapefruits and other types of citrus. With its different varieties, anyone
living Kenya should be able to find tangerine cultivars that will thrive in
their area, if they get full sun. Some varieties, such as the Citrus reticulata
that is Dancy variety are heat-tolerant and do best when it is hot, but other
types, including the Citrus reticulate, that is the Sunburst, do best when it’s
on the cool side.
Planting
A planting
hole size of 2ft by 2ft by 2ft is established and manure of about 20kg per hole
is mixed with the top soil and then put in the hole. Planting is done and
watering should be done at least twice a day in the initial stages of planting.
Thinning
Some
trees will produce large quantities of tangerines, resulting in fruit that does
not develop well or possibly even broken tree branches if the weight becomes
too much. While in most cases you don’t need to thin citrus fruit, sometimes
tangerines require it. If a tree has set a lot of fruit, remove some of it when
it is about an inch across by grabbing each fruit to be removed and gently
twisting it until it breaks free of the tree, continuing the process until you
have about 3 to 4 inches of space between each of the remaining tangerines.
Remove all the fruits from trees that are two years old or less, allowing the
trees time to become well-established before producing fruit.

Pruning
Dead
wood must be removed regularly. When the trees become too big and start growing
into one another, pruning is also recommended.
Branches
touching the ground hamper the removal of fruit lying underneath the tree,
impede irrigation and promote ant infestation of the trees. They should also be
removed.
Weeding
It
is very important to keep the area under the canopy free from weeds. This is
because the weeds compete for growth factors like nutrients and water and harbor
pathogens.
Watering
Tangerines
require moist, well-drained soil and will use lots of water as the fruit
develops, but over-watering can kill the tree by drowning the roots or
promoting rot. Gently soak the soil around the tree, then allow it to become
partly dry before soaking it again. Be consistent when watering the tree, since
fluctuating amounts of moisture will cause the tangerines to split. A drip
system is ideal for watering tangerine trees. Another option is to dig a ditch
around the tree, at the drip line, and fill it with water every week to 10
days, depending on your soil and climate conditions. In very dry areas, choose
a drought-tolerant variety such as the Sunburst for best results. Areas with
high humidity and moderate rainfall are also ideal for tangerine farming.
Soil
Tangerine
oranges grow well in well-drained soils with a pH range of 5.5 to 7.5 and altitudes of 0 to 1200 meters above sea level
.
They do not thrive in waterlogged soils, which can lead to root rot and other
diseases.
Fertilizer
Feeding
tangerine trees is important if you want to have a healthy tree and get a good
crop of fruit each year. It’s recommended that you apply a fertilizer designed
especially for citrus trees, as the trees are heavy users of zinc, nitrogen and
iron. Follow given directions to determine the correct amount for your tree,
and divide the yearly dose into thirds, applying the first feeding in the
spring (March- May) just before the tree blooms; the next dose two months
later; and the final feeding a month after that. Don’t feed the tree late,
typically after July, as you may end up stimulating new growth that will be too
tender to survive the cold season.

Common Pest and Diseases
Pests
These include: mealy bug, false
coding moth, aphids, black flies, mites, thrips
Management
- Monitoring: Regularly inspect your trees for signs of pests.
- Cultural Practices: Maintain tree health with proper irrigation, fertilization, and pruning.
- Biological Control: Introduce or conserve natural predators such as ladybugs, lacewings, and parasitic wasps.
- Chemical Control: Use pesticides judiciously, and opt for targeted, low-toxicity options when necessary. Always follow label instructions.
Diseases
These include: Rust, powdery
mildew, Citrus black spot, citrus greening, anthracnose, citrus canker,
leprosis, bacterial spot
Management
- By the use of disease free planting material to avoid diseases.
- Choosing rootstocks and cultivars that are tolerant or resistant to prevalent diseases
- Also application of fungicides such as copper, sulfur, clay powder and fennel oil is recommended. Copper can control several disease problems. However, it must not be forgotten that high Copper accumulations in the soil is toxic for soil microbial life and reduce the cation exchange capacity
Maturity
Tangerines
mature between 2-3 years. An acre can occupy 200 seedlings with a spacing of 5
by 5m. Profitability starts at around 5 years where each plant can produce more
than 300 fruits.
Harvesting
Tangerines
are harvested from March to August, when their characteristic color which is yellow,
orange and or red, depending on the variety spreads over 75% of the surface of
the fruit. Hand picking is recommended.

Mature Tangerine can produce a minimum of 300 fruits per year. The current
price of each fruit at the farm gate is Ksh. 20.This means you can get about
Ksh. 6000 per tree and with 200 trees per acre you can manage farming profitably.
- Cost per seedling: ksh.350
- Seedlings per acre: 200
- Spacing: 5m by 5m
- Fruit price: 150 per kg depending on variety
