Common Name: Melon

General Information

Cucumis melo is a climbing annual plant, producing stems around 1.5 metres long that sprawl along the ground or into other plants where they attach themselves by means of tendrils.
The plant is widely cultivated for its edible fruit, in both gardens and commercially, from the warm temperate zone to tropical areas.

Known Hazards

The sprouting seed produces a toxic substance in its embryo[].

Botanical References

Range

Probably native of Asia, though it has been in cultivation for so long its native habitat is obscure.

Habitat

Not known in a truly wild situation, though sometimes found as a weed of cultivated fields[], probably as an escape from gardens.

Cultivation Details

Melons are cultivated from the warm temperate zone through to the tropics, where they can be grown at elevations up to 1,000 metres. They grow best in areas where annual daytime temperatures are within the range 18 - 30°c, but can tolerate 9 - 35°c[]. They are killed by frost[]. They prefer a mean annual rainfall in the range 1,000 - 1,300mm, but tolerate 900 - 2,500mm[]. They grow best in areas without too much rainfall or too high a humidity, since these conditions reduce fertilization and lead to diseases of the leaves[].
Requires a rich, well-drained moisture retentive soil and a warm, very sunny position[]. Prefers a pH in the range 6 - 7.5, tolerating 5 - 8.7[].
It takes 3 - 4 months to produce a crop from seed[].
Individual plants are usually allowed to bear about four melons, and a crop of melons should yield about 5 - 30 tonnes/ha, with an average about 11 - 13 tonnes/ha[].
This is a very variable species that has long been cultivated for its edible fruit. As a result, a number of distinct forms have arisen and there are many named varieties within each of these forms[, , ]. These forms have been classified by botanists into groups as detailed below. Each of these groups has been given a separate entry in the database.
Cucumis melo agrestis. A wild form of the melon. It is not usually grown for its fruit but is of potential value in breeding programmes.
Cucumis melo cantalupensis. The cantaloupe or netted melons.
Cucumis melo chito. The orange melon. This form occasionally escapes from cultivation and is naturalized in some tropical and sub-tropical areas.
Cucumis melo conomon. The pickling or sweet melon. This form is also of value in breeding programmes for disease resistance.
Cucumis melo dudaim. The pocket melon.
Cucumis melo flexuosus. The serpent melon.
Cucumis melo inodorus. The honeydew melon.
Cucumis melo momordica. The snap melon. This form is also of value in breeding programmes for pest and disease resistance.

Edible Uses

Fruit - raw[, , , ]. Very watery but with a delicate flavour, it is very refreshing. Rich in vitamins B and C[]. The flesh of the fruit can be dried, ground into a powder and used with cereals when making bread, biscuits etc[]. The size of the fruit varies widely between cultivars but is up to 10cm long and 7cm wide[].

Seed - raw[, , ]. Rich in oil with a nutty flavour but very fiddly to use because the seed is small and covered with a fibrous coat[]. The seed contains between 12.5 - 39.1% oil[].

An edible oil is obtained from the seed[, ].

Medicinal

The fruits can be used as a cooling light cleanser or moisturiser for the skin[]. They are also used as a first aid treatment for burns and abrasions[].

The flowers are expectorant and emetic[].

The fruit is stomachic[].

The seed is antitussive, digestive, febrifuge and vermifuge[]. When used as a vermifuge, the whole seed complete with the seed coat is ground into a fine flour, then made into an emulsion with water and eaten. It is then necessary to take a purge in order to expel the tapeworms or other parasites from the body[].

The root is diuretic and emetic[].

The leaves are used to treat scrotal hernias[].

Agroforestry Uses:

Grows well with corn and sunflowers but dislikes potatoes[, ]. The weeds fat hen and sow thistle improve the growth and cropping of melons[].

Other Uses

The seed oil is used as a humectant and skin conditioner in commercial cosmetic preparations[].

Propagation

Seed - can be sown in situ or in containers. Germination should take place within 2 weeks. When using containers, sow 2 or 3 seeds per pot and thin out to the best plant. Grow them on fast and plant out when about 15cm tall[].
