INTRODUCTION
Family
he Malay apple is a medium-size tree that has been cultivated for a long time in the tropics. Its native range is
thought to lie somewhere between Melanesia and Southeast Asia, but exactly where is not known. It was originally
found in lowland to montane rainforest. Today, over most
of its range it is found in homegardens and plantations,
although rarely in montane forest. In a few places where it
was introduced (e.g., Hawai‘i), it is found in native forest
as relictual stands from which it does not spread (no local birds can disperse the fruit). Because of its large fruit
and seed, it is rarely invasive but may persist in groves that
were formerly planted in native forest. he tree is valued
for its large edible fruits that are eaten fresh. Because of
its fruits seasonality and short shelf life, it has not been
grown in large plantations for export and is thus mostly
locally consumed rather than exported. It can be a signiicant cash crop, however, when sold in local markets. hus
it is ideal for homegardens and casual intercrop plantings.
It thrives in areas with suicient year-round rainfall and
can be irrigated in areas with a dry season. he tree is also
widely used in traditional medicines. he wood is of average quality but is little used because of the availability of
better timber species.
Myrtaceae (myrtle Family)
DISTRIBUTION
Native range
It has been cultivated for so long that its origin is uncertain.
However, it is native to somewhere in the Indo-Malayan
region or Southeast Asia, probably originally in lowland
rainforest.
Current distribution
It is now cultivated throughout the tropics, especially in
Indo-Malaysia, Southeast Asia, Melanesia, Polynesia
(where it was an ancient introduction as far east as Hawai‘i),
and Micronesia (where it is apparently a modern introduction in the eastern part of its range, Pohnpei and Kosrae).
In some places, such as in Melanesia (e.g., Vanuatu and
Fiji), it appears to be naturalized. In Hawai‘i, it is common
in forest groves that are probably remnants of former cultivation, but the tree does not readily spread from these.

Size
It grows up to 16 m (53 ft) or more in height but is often
only 5–12 m (16–40 ft) when grown in cultivation.
Form
he crown is oblong, pyramidal, or cylindrical, sometimes sub-tiered, with many small horizontal to ascending
branches. he bole is short and often luted.
Flowers
An inlorescence of short, few-lowered cymes up to 6 cm
(2.4 in) long is borne on the trunk or older branches. Calyx
turbinate, 1.2–1.8 cm (0.5–0.7 in) long, notched to form 4
pale yellow, rounded lobes 4–6 mm (0.2–0.3 in) long. Corolla with 4, red or pink (rarely white), suborbicular petals
7–11 mm (0.3–0.4 in) long, early caducous. Ovary inferior,
style long, with a simple style up to 2.5 cm (1 in) long. Stamens many (ca. 200), free, red, 1–2 cm (0.4–0.8 in.) long.
Flowering is usually seasonal, from 1–2 months in dura-

tion, but it varies widely from place to place and
even from year to year. In some areas, Malay
apple lowers two or three times per year. It occurs mostly in the spring (August–November)
in the South Paciic, but from May–February
in Fiji, in February and from June–October
in Vanuatu, and from May–June on Java. In
Hawai‘i, lying north of the equator, it lowers
from March–April, and in Pohnpei lowering
apparently occurs twice a year, in November–
December, and again in April–May. Trees begin
lowering at an age of 7–8 years.
Leaves
Leaves are opposite, simple, blade ovate to oblong, mostly 10–30 cm (4–12 in) long, often affected by insect galls, acute to rounded at the
base, acute to acuminate at the tip; leaf surfaces
are glabrous, glossy green with entire margins
and a thick, red petiole 2–10 mm (0.1–0.4 in)
long.
Fruit
Fruit a large, leshy, ovoid berry 3–7 cm (1.2–2.8
in) long, glossy red or sometimes white or white
with red streaks. Like lowering, fruiting is variable. In the South Paciic, it usually occurs in
late spring to summer (November–February),
but from September–May in Vanuatu, and from
August–September in Java. In India, the main
crop occurs from May–July and there is often
a second crop in November and December. In
Hawai‘i, fruiting occurs in June to November
or even December, and in Pohnpei in January–
February and June–December. Latitude and local climate may be the major determinants of
lowering time. Fruits mature in 60 days from
the full opening of the lowers and fall quickly
once fully ripe. Ripened fruit deteriorate rapidly. he trees can produce fruit within 5 years
after planting.
Seeds
Each fruit contains a single large, subglobose
seed or a pair of subglobose to hemispherical
seeds 1.6–2 cm (0.6–0.8 in) in diameter, lightbrown externally, green internally, and somewhat meaty in texture. he fruits of some trees
are entirely seedless. In its native range, the

seeds are probably dispersed by birds (particularly pigeons), who eat the fruit, and also by
Species Profiles for Pacific Island Agroforestry (www.traditionaltree.org)
3
fruit bats. Where suitable dispersers are absent, the tree
disperses poorly, probably not spreading far from the parent tree (and hence is not naturalized in these areas).
Rooting habit
No information available.
Similar species/look-a-likes
It is similar to Syzygium aqueum (bell or water apple), a
tree cultivated in the Paciic for its edible fruits. he fruits
of this species, however, are smaller and bell-shaped (widest toward the free end), and the lowers are white rather
than red. It is also similar to Syzygium samarangense, a tree
sometimes cultivated in the Paciic and becoming naturalized in native forests. he lowers of this tree are white and
the leaves are subsessile (i.e., having the petioles less than 7
mm [0.25 in] long). All three species are used interchangeably where they occur together. Syzygium malaccense also
difers from the other two by typically having the inlorescences borne on the branches and occasionally on the
trunk rather than at or near the ends of the stems.
GENETICS
Known varieties
Two color forms exist over most of its range, the common
one with red fruits and lowers, and a less common one
with white fruits and lowers. hese have not been given
taxonomic rank, but in Polynesia and Melanesia they are
recognized in the local languages (usually with a color
qualiier added to the native name). Some commercial
companies recognize many selected clones. Trees of selected varieties are available from local tropical fruit nurseries,
especially in south Florida.
Culturally important related species in the genus
Many native trees belonging to the genus Syzygium are
found on the high islands of the tropical Paciic, some of
them important timber species. Two other species are cultivated in western Polynesia (and native to Fiji), Syzygium
corynocarpum and Syzygium neurocalyx. he seasonal fruits
of these two species were once commonly used for personal
adornment (i.e., for making fragrant leis) and sometimes
for scenting coconut oil.
ASSOCIATED PLANT SPECIES
Malay apple does not have any speciic associates, as it occurs over such a wide geographical area, each with its own
lora. However, it is typically grown in mixed plantings in
4
Syzygium malaccense (Malay apple)
and around villages together with other cultivated species,
such as coconut, banana, breadfruit, etc.
Associated species commonly found in native
habitats
Not usually found in native forest, but when it is, it occurs
with numerous species.
Species commonly associated as aboriginal introductions in Paciic islands
Several other fruit trees were aboriginal introductions into
the Paciic islands (Polynesia at least). hese include Tahitian chestnut (Inocarpus fagifer), breadfruit (Artocarpus
altilis), and Polynesian plum (Spondias dulcis).
ENVIRONMENTAL PREFERENCES
AND TOLERANCES
Climate
he tree thrives in cultivation in volcanic soil with suicient year-round rain in the humid and subhumid tropics.
It does not do well on atolls, either because of the calcareous soil or insuicient rainfall. he tree is restricted to the
tropics, being intolerant of any frost. Hence, it is found
only in tropical regions. It does well at cool elevations, as at
higher elevations in Hawai‘i, either planted around houses,
where it can be watered during dry periods, or in mountain
forests where there is suicient natural rainfall.
Elevation range
he tree can grow from near sea level to 1200 m (4000 ft)
but is usually found below 600 m (2000 ft).
Mean annual rainfall
he lower rainfall range is 1500 mm (60 in), and there is
no upper limit.
Rainfall pattern
It prefers year-round rain but can tolerate seasonal rain as
long as there is no extended dry period. Trees grown in
areas with a seasonal dry period need to be irrigated during
the drought.
Mean annual temperature
24°–27°C (75–81°F) (estimate)
Minimum temperature tolerated
It is intolerant of frost.
Soils
he tree grows vigorously on a range of soil types from
sand to heavy clay. It tolerates moderately acid soil but in
high pH soil it develops nutritional deiciencies that can be
overcome with the occasional use of micronutrient sprays.
It does not do well in highly alkaline situations. In India,
the tree reportedly grows best on the banks of ponds, lakes,
and streams where there is good drainage.
Soil texture
It tolerates medium to heavy texture soils (loams, sandy
clay loams, sandy clays, clay loams, and clays).
Soil drainage
It grows in soils with free drainage.
Soil acidity
pH 6.1–7.4
Salt spray
It is not known to be tolerant of salt spray.
Wind
It does not do well in strong wind because of its fragile
wood, according to some sources, but others note that the
“trees are quite wind resistant.” he tree has been used in
windbreaks.
GROWTH AND DEVELOPMENT
When grown from seed, germination occurs in 4–6 weeks.
he trees grow fast when weeded and mulched during the
irst year or two. After 5 years, faster growing individuals
can start producing fruit.
Growth rate
here is no data available, but growth rate is moderate even
in early years, likely less than 75 cm (30 in) per year.
Special soil tolerances
None known.
Reaction to competition
he tree is tolerant of competition, as it thrives in old forest
but does best when periodically weeded when young.
Tolerances
Drought
It does not do well in areas with a seasonal drought, unless it is
irrigated during the dry season or grows near a water body. Established trees can tolerate more extensive periods of drought,
up to 6 months. Signiicant leaf fall occasionally occurs, al-
though the tree will not totally defoliate.
Full sun
he tree grows well in full sun if given enough water.
Shade
Partial shade is tolerated.
PROPAGATION
he seeds germinate well, and many can usually be found
sprouting under their parent tree. While seed propagation
is common, air-layering has been successfully used, and
cuttings have been rooted in sand in Hawai‘i. hese vegetative methods of reproduction are used especially on high
yielding individuals. Some people prefer to graft superior
varieties onto seedling stocks.
Propagation from seed
Fire
It is probably not adapted to ire, as it is native to wet tropical rainforest, which is not subject to ire.
Frost
he tree is intolerant of frost.
Waterlogging
he tree does not tolerate waterlogging. Where it is grown
in wet places (such as the banks of irrigation canals), it is
usually put in mounds or other slight elevations to keep
the roots from being in waterlogged soil for prolonged periods of time.
(after Wilkinson and Elevitch 2003)
Seed collection
Seeds are best collected during the fruiting season, which
varies from place to place. hey have short viability, so they
should be taken from the fruit and planted right away. he
most readily available supply of seeds is found under cultivated trees. Seeds should be collected from individual trees
with the most desirable fruits.
Seed preparation
No special preparation is needed for the seeds. It is best to
remove most of the lesh in order to minimize fungal attacks. his can be easily done by lightly rubbing the seeds
together in water. No pretreatment is needed prior to sowing.

Size at outplanting
he size at outplanting is ideally 35 cm (1 ft) or larger.
Vegetative propagation

ElEvitCh
While seed propagation is common, superior types are
multiplied vegetatively. Air-layering and cuttings are
both successful methods. Air-layering is best carried out
on young branches 1–2 years old. A branch diameter of
1–2 cm (0.4–0.8 in) and length of 30–45 cm (12–18 in) are
ideal. Pick branches that are easy to access, and preferably
with stems that are shaded by other branches. Air-layering
works well any time of year, but the mother plant should
be in good health and have adequate water and nutrition
available. Cuttings have been successfully rooted in sand
in Hawai‘i. Cuttings are ready for transplanting 6 weeks
after rooting.
Seed storage
he seeds are leshy and do not retain viability when stored
or dried. Because of their short viability, they should be
planted straight out of the fruit. If necessary, seeds can be
stored 2–3 weeks wrapped in a lightly moistened medium
such as paper towel and kept in a cool, dark place.
Media
When growing seedlings in containers, use a well drained
potting medium such as 50% coarse peat moss, 25% perlite, and 25% vermiculite amended with a little compost,
dolomite lime, gypsum, micronutrients, and slow release
14-14-14 fertilizer. Also, natural soils mixed with sand, volcanic cinders, or composted organic matter can be used for
seedling production, although these may contain live weed
seeds that increase maintenance in the nursery.
Growing area
Full sun or light shade are recommended. As seeds readily
germinate under fruiting trees, seedlings can also be grown
in deep shade, although growth will be slower. Seeds can
be grown in containers in the nursery or sown directly in
the ield.
Germination
Seeds are planted no more than 4 cm (1.5 in) deep in nurseries or directly in the ield. he seeds will germinate in
4–6 weeks. he germination rate is high for fresh seed (and,
indeed, proliic under trees in the wild).
Time to outplanting
If seedlings are grown in containers rather than directly in
the ield, the seedlings are typically transplanted to their
inal destination when 8 months old.

DISADVANTAGES
he fruit is only slightly sweet, although it makes a refreshing snack when picked and eaten out-of-hand. he fruit
is crisp, delicate, and rather watery, with a very short shelf
life, and is therefore diicult to market commercially. It is
rarely grown in commercial plantations, but mostly as a
tree or two in homegardens or plantations. he fruit does
not make very good jams, because most of the taste is lost
during preservation.
Potential for invasiveness
In most places where it has been introduced it is unable to
spread. It is not considered invasive, although it has naturalized in isolated areas where it was introduced.
Diseases and pests
he tree is fairly resistant to pests. he trees are frequently
attacked by termites in India. It is reported that sap-feeders, defoliators, miners, and borers have been found on the
foliage and on dead stems. Native fruit lies attack the tree
in Vanuatu, but otherwise very little is known about this,
because the tree has not been a major commercial crop. In
Hawai‘i, rose beetles often attack the foliage of young trees,
which can suppress early growth. Rose beetle attacks usually diminish in older trees.
Host to crop pests/pathogens
Not known as a host for pests.
AGROFORESTRY/ENVIRONMENTAL
PRACTICES
Crop shade/overstory
Not reported to be used for this, however it is frequently
found in and among numerous crops in homegardens.
Homegardens
It is commonly used in homegardens, being planted around
houses and in plantations.
Windbreaks
Malay apple has been used in windbreaks.
Native animal/bird food
he tree has fruit that is edible by birds. It is also a food
source for fruit bats during its fruiting times.
Ornamental
he tree is quite attractive and highly ornamental, especially when in bloom, and it makes a nice shade tree.

USES AND PRODUCTS
he Malay apple was brought to the Paciic islands by early
inhabitants and was one of the few fruit trees available to
them. It was once an important supplemental (and seasonal) fruit crop. Today, because other more proliically
fruiting and better tasting fruits are available (e.g., mango and papaya), cultivation of Malay apple has decreased.
However, it is still a useful crop and is easily cared for in a
homegarden. he wood is average but little utilized since
other better woods were and are available.
Fruit
he ripe fruit is eaten raw. he skin is thin and the lesh is
crisp and white. he slightly sweet taste is refreshing and
can be a crunchy addition to a mixed fruit salad. Although
not suited for jams or jellies, the half-ripened fruit can be
pickled. Pickled or preserved slices and sauces, very heavily
spiced, are found in southeast Asia. Wine is made from
the fruit in Puerto Rico.
Medicinal
In Samoa an infusion of the crushed leaves or scraped bark
is very commonly taken as a potion, the leaves are chewed
and the juice swallowed, or the leaf juice is dripped into
the mouth of an infant to treat mouth infections. In Tonga
an extract of bark scrapings is commonly administered
to treat throat infections and stomachache, and is an ingredient in various remedies for a complex of abdominal
ailments known as kahi. An infusion of the bark is used
to treat coughs in Futuna and Niue. In the Cook Islands
a solution of the crushed leaves, or to a lesser extent the
grated bark, is widely used to treat thrush, and a solution
of the grated bark is sometimes administered as an emetic.
Various uses, some of them as a purgative, are reported in
Tahiti, few if any of them dealing with children’s mouth

infections. In the Marquesas coconut oil in which fragments of the bark have been soaked is taken as a purgative.
In Hawai‘i the bark was crushed and its juices taken for
sore throat, juice extracted from the bark was mixed with
salt and applied to cuts, and the leaves were crushed and
ingested for bronchitis. he use of the plant for treating
mouth infections such as thrush is reported from as far
away as Indonesia and is likely to be an ancient Polynesian
practice. In Malaysia the powder from the dried leaves is
reportedly used on a cracked tongue, a preparation of the
root is a remedy for itching, and a preparation of the root
is given to alleviate swelling. he root bark is used to treat
dysentery and serves as an emmenagogue (promoting menstrual function) and abortifacient. Cambodians reportedly
take a decoction of the fruit, leaves, or seeds as a febrifuge
(against fever). In Brazil various parts of the plant are used
as remedies for constipation, diabetes, coughs, pulmonary
catarrh, headache, and other ailments. Numerous other
uses are reported over the range of the species.
Beautiful/fragrant flowers
he lowers are very attractive but fragile and not easily
used. After picking, they soon shed numerous red stamens.
Early sources in Fiji noted “the natives gathering handfuls of them [the showy red stamens] to strew on their
heads.” In Hawai‘i both blossoms and fruit were used to
make leis.
ters, railway ties, and for carving bowls. In Chuuk it has
been used to make outrigger booms.
Craftwood
In Hawai‘i the wood was considered sacred and carved
into religious images.
Fuelwood
Occasionally used for irewood, the tree is not usually so
utilized, especially if the tree still is producing fruits.
Canoe/boat/raft making
he wood is used to make outrigger booms in Chuuk.
URBAN AND COMMUNITY
FORESTRY
Because of its beauty, low demand for care, and abundant, refreshing fruit, Malay apple is well suited for urban environments. he tree was widely introduced into
Paciic islands by native people and integrated into their
homegardens, medicine, and spiritual beliefs. Planting and
preserving this tree in urban environments forms a living
connection to aboriginal cultures.
Size in an urban environment
Malay apple typically reaches 5–12 m (16–40 ft). Pruning
can control the tree’s size, although heavy pruning can kill
the tree.
Timber
he reddish, soft to hard, tough and heavy timber is diicult
to work, as it is inclined to warp. However, it is sometimes
employed for construction as house posts, fence posts, raf-

Root system

would cause problems with pavement.
Products commonly used in a Paciic island
household
he fruit is best to eat freshly picked from the tree, which
makes the tree ideal for homegardens. It is also used for a
multitude of home remedies.
Light requirements
he tree prefers full sun but it can grow well with light
shade, especially if the shade is from the side rather than
overhead.
Water/soil requirements
Exceptional ornamental values
It grows in a wide range of soils but requires free drainage. It grows best in moist valleys, along waterways, and
in other situations where soil moisture is high. In urban
environments, areas with roof or gray-water run-of may
be preferred.
he tree lowers abundantly as many as three times per
year, illing the trunk and inner part of large branches with
bright red or white, mildly fragrant lowers, which can be
seen through openings in the canopy. Each lowering period lasts about 2 weeks, leaving the ground under the tree
temporarily carpeted in red or white.
Life span
he longevity is unknown, although several decades is expected.
Varieties favored for use in homegardens or public
areas
here are two color forms, red and white, both of which
are grown in homegardens. Trees with large and especially
sweet fruit are sometimes cloned by cutting or air-layering.
Use as living fence, hedge or visual/noise barrier
Because of its irregular canopy and slow regrowth after
pruning, Malay apple is rarely used for these purposes. It
is, however, used in multi-row, multi-species windbreaks
that take up more space than usually available in urban
environments.
Birds/wildlife

and after falling to the ground. Pigs most certainly will eat
fallen fruit.
Maintenance requirements
Once established, the tree rarely requires any special care.
Mulching with organic materials, such as grass clippings
or other plant foliage (shredded or not), will help conserve
soil moisture while slowly releasing nutrients into the soil.
of growth. he tree can be pruned to ensure that fruit is
borne low for ease of picking. However, the tree regrows
only weakly from pruning, and heavy pruning can kill the
tree.
Advantages and disadvantages of polycultures
It does well mixed with other species and is not usually
grown in monocultures.
Nuisance issues
Estimated yields
Fruits drop quickly after ripening and attract rats and fruit
lies. If the juicy fruits are allowed to ripen and fall to the
ground, the tree could be considered “messy.” he fruit decomposes rapidly, and usually there are no ofensive associated smells or other problems.
Yields of 21–85 kg (48–188 lb) per tree have been reported.
Hazards
None.
Common pest problems
Serious pest problems are rare. In Hawai‘i, rose beetles
commonly feed on young trees, defoliating them periodically. Without leaves, the tree’s growth is slowed. Once
trees reach 5–7 years, problems with rose beetles usually
disappear. Keeping young trees healthy by mulching and
ensuring continual soil moisture will help them recover
from rose beetle attacks.
COMMERCIAL PRODUCTS
he tree is primarily important as a supplemental fruit
crop. he fruit is mostly consumed raw and locally rather
than being exported. For marketing, the ripe fruits must be
hand-picked to avoid damage and to have a longer shelflife. However, because the fruit is seasonal and somewhat
insipid, it is best eaten immediately after harvest and does
not have much commercial value other than being sold in
local marketplaces during the fruiting season. he wood is
of some value but is not used commercially.
Spacing for commercial production
In India, commercial trees are spaced 6–10 m (20–33 ft)
apart in ields prepared and enriched as for any other crop,
and thereafter they require little care except for elimination of weeds, periodic fertilization, and plentiful irrigation
in very dry weather. However, the Malay apple is usually
grown in homegardens mixed with other species.
Management
Weeding needs to be done only during the early stages
10
Syzygium malaccense (Malay apple)
On-farm processing methods required to access
market
Because of its short shelf life and fragile skin, the fruit is
not very suitable for markets, except at the local level. he
sooner the fruit is chilled, the longer the shelf life; chilled
soon after harvest, the shelf life may be extended from 2
days to a week.
On-farm processing methods
In ancient Hawai‘i the fruit was partially dried for palatability and storage.
Markets
It is rarely exported, except to cities near where the trees
are grown (e.g., in Singapore).
INTERPLANTING/FARM
APPLICATIONS
Malay apple is often planted in and among other trees such
as citrus, cofee, macadamia nuts, etc. It is a good fruit for
eating while working in the ield. By planting at various
elevations on a farm, the season fruits are available can be
extended by several weeks.
