Cultivation Details

Honeydew melons can be 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[].

Edible Uses

Fruit - raw[, , , ]. Very watery but with a delicate sweet flavour. Unlike the cantaloupe melon it is not aromatic[]. A very refreshing fruit, especially on a hot day. 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[].

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

An extract of the fruit is used as a skin conditioner in commercial cosmetic preparations[].
An extract of the root is used as a humectant and skin conditioner in commercial cosmetic preparations[].
An extract of the seed is used as a 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[].
