Cultivation Details

Cucumis anguria is cultivated mainly in the tropics and subtropics, though it can also succeed in regions of the temperate zone with long, hot summers. It grows best in areas where annual daytime temperatures are within the range 21 - 28°c, but can tolerate 8 - 32°c[]. The plant cannot tolerate frost. It prefers a mean annual rainfall in the range 800 - 1,000mm, but tolerates 300 - 1,700mm[].
Requires a rich, well-drained moisture retentive soil and a warm very sunny position[]. Prefers a pH in the range 6 - 7.5, tolerating 5.5 - 8.3[]. It prefers warm, moderate humid conditions. It is sensitive to cold, susceptible to fungal diseases, and attacked by aphids and cucumber beetles[].
The plant is an invasive weed in parts of North America and in Australia, and a serious weed in peanut fields of the southern United States[].
The fruits can be harvested 40 - 80 days from sowing the seed or planting out[].
There are two main forms of the plant, the wilder form that has a bitter taste and a cultivated form that is more or less free of the bitterness[]. There are many named varieties of the non-bitter form.
The plant is believed to be derived in cultivation from the tropical Brazilian species C. Longipes. Hook.[]
