Origin:
The mango is native to southern Asia, especially Burma and eastern
India. It spread early on to Malaya, eastern Asia and eastern Africa.
Mangos were introduced to California (Santa Barbara) in 1880.
Forms:
The mango exists in two races, one from India and the other from the
Philippines and Southeast Asia. The Indian race is intolerant of
humidity, has flushes of bright red new growth that are subject to
mildew, and bears monoembryonic fruit of high color and regular form.
The Philippine race tolerates excess moisture, has pale green or red new
growth and resists mildew. Its polyembryonic fruit is pale green and
elongated kidney-shaped. Philippines types from Mexico have proven to be
the hardiest mangos in California.
Adaptation:
Mangos basically require a frost-free climate. Flowers and small fruit
can be killed if temperatures drop below 40° F, even for a short period.
Young trees may be seriously damaged if the temperature drops below
30° F, but mature trees may withstand very short periods of temperatures
as low as 25° F. The mango must have warm, dry weather to set fruit. In
southern California the best locations are in the foothills, away from
immediate marine influence. It is worth a trial in the warmest cove
locations in the California Central Valley, but is more speculative in
the coastal counties north of Santa Barbara, where only the most cold
adapted varieties are likely to succeed. Mangos luxuriate in summer heat
and resent cool summer fog. Wet, humid weather favors anthracnose and
poor fruit set. Dwarf cultivars are suitable for culture in large
containers or in a greenhouse.
DESCRIPTION
Growth Habit:
Mango trees make handsome landscape specimens and shade trees. They are
erect and fast growing with sufficient heat, and the canopy can be broad
and rounded, or more upright, with a relatively slender crown. It is
ultimately a large tree, to 65 ft., but usually half that size in
California. The tree is long-lived with some specimens known to be over
300 years old and still fruiting. In deep soil the taproot descends to a
depth of 20 ft, and the profuse, wide-spreading feeder roots also send
down many anchor roots which penetrate for several feet.
Foliage:
The leaves are dark green above and pale below, usually red while young.
The midrib is pale and conspicuous and the many horizontal veins
distinct. Full-grown leaves may be 4 to 12-1/2 in. long and 3/4 to 2 in.
wide, and are generally borne in clusters separated by a length of naked
stem bearing no buds. These naked stems mark successive flushes of
growth. Each flush of growth will harden off to a rich green color
before the next flush of growth begins.
Flowers:
The yellowish or reddish flowers are borne in inflorescences which
appear at branch terminals, in dense panicles of up to 2000 minute
flowers. These flowers respire a volatile substance, causing allergic
and respiratory problems for some persons. Pollinators are flies,
hoverflies, rarely bees. Few of the flowers in each inflorescence are
perfect, so most do not produce pollen and are incapable of producing
fruit. Pollen cannot be shed in high humidity or rain. Fertilization is
also ineffective when night temperatures are below 55° F. Mangos are
monoecious and self-fertile, so a single tree will produce fruit without
cross pollination. Polyembryonic types may not require pollination at
all. Branches may be ringed to induce flowering, but the results are
mixed.
Fruits:
The fruits grow at the end of a long, stringlike stem (the former
panicle), with sometimes two or more fruits to a stem. The fruits are 2
to 9 inches long and may be kidney shaped, ovate or (rarely) round. They
range in size from 8 ounces to around 24 ounces. The flower scar at the
apex is prominent, in some cultivars bulging from the fruit. The
leathery skin is waxy and smooth, and when ripe entirely pale green or
yellow marked with red, according to cultivar. It is inedible and
contains a sap that is irritating to some people. The quality of the
fruit is based on the scarcity of fiber and minimal turpentine taste.
The flesh of a mango is peachlike and
juicy, with more or less numerous fibers radiating from the husk of the
single large kidney-shaped seed. Fibers are more pronounced in fruits
grown with hard water and chemical fertilizers. The flavor is pleasant
and rich and high in sugars and acid. The seed may either have a single
embryo, producing one seedling, or polyembryonic, producing several
seedlings that are identical but not always true to the parent type. It
is impossible to distinguish true-to-type from zygotic seedlings from
the same fruit. Some seedlings produce numerous tiny, parthenocarpic
fruits which fail to develop and abort. Mango trees tend to be alternate
bearing.
CULTURE
Location:
The mango grows to a good size and casts a dense shade, but the roots
are not destructive. It requires full sun and perfect air drainage in
winter. It does best at the top or middle level of a slope. A windbreak
should be provided in exposed areas. The trees may also need staking. In
the desert it needs the shade of other trees; or plant on the north side
of the house. In the garden or near the coast, plant against a south
wall, or in an area surrounded by paving, to provide maximum heat. In
the greenhouse, full light and free air movement are important to avoid
disease.
Soil:
Mangos will grow in almost any well-drained soil whether sandy, loam or
clay, but avoid heavy, wet soils. A pH between 5.5 and 7.5 is preferred.
They are somewhat tolerant of alkalinity. For good growth, mangos needs
a deep soil to accommodate their extensive root systems.
Irrigation:
Irrigation should start when the weather warms: February in the desert,
April at the coast. Continue every one to two weeks, more often in light
soils, nearly continuously in the desert, until the fruit is harvested.
Irrigation may be discontinued when rains are sufficient to maintain
soil moisture. In the greenhouse keep watered until the fruit is
harvested, then reduce to the minimum required to avoid wilting.
Watering is then increased after one to two months to initiate a new
bloom and growth cycle.
Fertilization:
Mango trees require regular applications of nitrogen fertilizer to
promote healthy growth flushes and flower production. Chelated
micronutrients, especially iron, are also often necessary. A feeding
program similar to one used for citrus is satisfactory, but do not
fertilize after midsummer. Organic fertilizers perform best, since the
trees are subject to fertilizer burn. Young trees are particularly
sensitive to over-fertilizing, but respond well to fish emulsion. Sandy
soils require more fertilizer than loam or clay.
Pruning:
Healthy trees require little pruning, although pruning to stimulate new
growth promotes uniform annual bearing. Removing some flower clusters
during a heavy bloom year may also alleviate alternate bearing. Mangos
may be pruned to control size in late winter or early spring without a
loss of fruit. Sap and debris can cause severe dermatitis, similar to
poison oak. It is best to avoid burning prunings or litter.
Frost Protection:
During the first two years, the trees should be given some protection
such as an overhead cover during any frost threat. Once the tree is 3 to
4 feet high, overhead protection is difficult but still worthwhile,
especially if an unusual cold snap is predicted. Frost damage can also
be avoided by erecting an overhead lath shelter, orchard heating,
placing lights under the canopy, or using foam or straw trunk wraps. Do
not prune dead parts until all frost danger is past.
Propagation:
Seedlings are a gamble. Supermarket
fruits may have been treated to sterilize, or chilled too long to remain
viable. These seeds are normally discolored gray. To grow mangos from
seed, remove the husk and plant the seed (before it dries out) with the
hump at soil level. The seeds normally germinate in two to four weeks,
and do best with bottom heat. Multiple polyembryonic seedlings should be
carefully separated as soon as they have sprouted so not to loose the
cotyledons. Seedling mangos will bloom and bear in three to six years.
Some success at grafting can be
obtained in April and September, but better luck is more likely during
May through August. Small plants with a diameter of a pencil graft well
with the common whip graft. On larger trees the crown groove bark graft
allows several scions to be put on at once. Fully grown trees may be
topworked by crown or groove bark graft, or prune hard and whip graft
sprouts later. Plastic bagging with a few drops of moisture improves the
graft's chances of being successful.
Graft in the second year, using cleft,
side or tongue (splice) graft in midsummer. Scion and stock should be
swelling for a new flush of growth. Grafts are most successful if the
leaves are allowed to remain below the graft, but remove suckers. Use
pencil-sized scions of hard wood with three or four nodes. Cover with
loose punctured white paper bag for shade.
If top working, do not dehorn the
entire tree at one time; leave at least two fully leafed branches
intact. Marcottage is feasible in humid climates or greenhouses, but
results in few plants. Although budding is rare in California; it can be
done by using a shield bud in an inverted T, at the moment the tree
begins a new growth flush. Cuttings are rarely successful, although
experiments have shown that rooting may be improved by treating with
ethylene, which destroys the root-inhibiting hormone in the cambium.
The Mango is a suitable and productive
tree for growing in a container or greenhouse. Start with established
plants of named cultivars. Select the finest Indian cultivars, which are
most rewarding for the effort involved. A large tub is required, with
casters for easy moving. In the greenhouse, the atmosphere should be
kept dry as possible to avoid anthracnose. Place a fan nearby to move
the air around trees and use ventilators. The plants should be hosed
down in the morning on a weekly basis to control mites. A regular
spraying of appropriate pesticides for anthracnose and mealybug may also
be needed.
The location of the intended planting
will dictate the choice of cultivars. Seedlings selected under
California conditions have provided cultivars suitable for coastal
counties. Florida cultivars are generally more suitable in the desert
and Central Valley.
Pests and Diseases:
Scale, mealybugs and mites are frequent pests in the greenhouse and
orchard. In the greenhouse, thrips often turn leaves rusty brown.
Malathion is the conventional spray for insect pests; sulfur works on
mites. Gophers are attracted to the roots. The flower panicles, young
fruit and leaves are subject to powdery mildew (Oidium mangiferae),
especially in rainy weather or frequent fog. A spray of powdered kelp at
bud break will often control it. Sodium bicarbonate and fungicide sprays
are also effective. Trees planted in pavement openings seldom develop
mildew.
Bacterial spot (Colletotrichum
oleosporides) distorts and turns developing leaves black and
disfigures developing fruit. Infection may spread to fresh young growth.
Anthracnose can be controlled with bimonthly applications of copper
spray or captan as a growth flush begins, and until the flowers open.
Resume spraying when the fruits begin to form. Mango trees are very
sensitive to root loss that can occur from digging, transplanting or
gopher damage. "Soft nose," a physical disorder of shriveling at the
fruit apex, seems associated with excessive nitrogen in soil. Exposed
fruits sunburn in high temperatures.
Fruit Harvest:
Mango fruit matures in 100 to 150 days after flowering. The fruit will
have the best flavor if allowed to ripen on the tree, although
winter-maturing fruits must be ripened indoors in coastal California.
Ripening fruit turns the characteristic color of the variety and begins
to soften to the touch, much like a peach. Commercial marketability
requires 13% dissolved solids (sugars). When the first fruit shows color
on tree, all of that size fruit or larger may be removed; repeat when
remaining fruit colors. Do not store below 50° F.The fruit ripens best
if placed stem end down in trays at room temperature and covered with a
dampened cloth to avoid shriveling. Mangos ripen in June from January
bloom in interior California, and October from April bloom on the coast.
Less time is required to mature greenhouse fruit.
Commercial potential:
The mango is the apple (or peach) of the tropics, and one of the most
commonly eaten fruits in tropical countries around the world. The fruit
is grown commercially on a small scale in Florida. In California a large
planting in the Coachella Valley has now reached production stage. The
quality of the fruit is generally comparable to Florida mangos, but has
other advantages., i.e. the lack of fruit fly and seed weevil
populations. Mexico, and to a lesser extent Central America, is a major
supplier to U.S. markets today.
