Cantaloupe

Sowing: Cantaloupe is direct-sown once frost danger has passed and soil has warmed to roughly 65 to 70°F, with seed set in groups of four to six spaced several feet apart and later thinned to two or three of the strongest seedlings; where seasons run short, seed can instead be started indoors four to six weeks before the last frost and transplanted once seedlings carry two or three true leaves and nighttime lows stay above 50°F, after a period of hardening off.

Siting: Plants need a full-sun site and fertile, moist, well-drained soil enriched with organic matter. Cantaloupe can be left to trail along the ground or trained up a cage or trellis, in which case the ripening fruit is cradled in a sling or hammock to keep it from tearing loose and splitting as it enlarges.

Watering: Consistent moisture is needed from germination through fruit set, applied at the base of the plant so the leaves stay dry and disease pressure is reduced. As the fruit nears maturity, watering is cut back to concentrate flavor and to keep the fruit from splitting.

Pests: Striped and spotted cucumber beetles and aphids are the insects most likely to trouble cantaloupe. Cucumber beetles are of particular concern because they can carry the bacterium responsible for bacterial wilt, a disease that has no treatment once a plant is infected, making early monitoring and beetle control important.

Diseases: The plant is also susceptible to powdery mildew, downy mildew, gummy stem blight, anthracnose, fusarium wilt, cucumber mosaic virus, fungal leaf spot, and scab. Risk is lowered by watering at the base rather than wetting foliage, spacing plants to allow air movement, clearing away diseased leaves and fruit in autumn, and avoiding repeated planting of cucumber-family crops in the same ground year after year.

Harvest: Fruit is typically ready 35 to 45 days after pollination, signaled by netted skin turning from green to yellow and by full slip, the point at which the melon separates easily from the stem and flavor peaks. Because ripeness can turn to over-ripeness quickly, fruit nearing maturity is checked daily.

Storage: Cantaloupe does not continue to ripen once picked; it will soften further but will not become any sweeter.

Culinary: Cantaloupe fruit is eaten fresh, added to salads, wrapped in prosciutto, or served as a dessert, valued for a watery but delicate flavor. The seeds are avoided, since a sprouting seed produces a toxic substance in its embryo.

Ornamental: As a climbing vine that attracts bees and other pollinators, cantaloupe also suits vertical growing spaces and is grown in edible and cottage gardens for its foliage and flowers as well as its fruit.

Cantaloupe belongs to Cucumis melo, whose wild ancestors are traced to Africa, with domestication estimated at nearly 3,000 years before present and later divergence into separate melon lines. Archaeological remains show the crop reaching China by about 5,000 years before present and Egypt and Iran during the second and third millennia BC, evidence of an early and wide spread through Asia and the Mediterranean.

The cantaloupe name itself dates to the 1400s, when melons brought from Armenia were grown at the papal estate of Cantaluppe near Rome and then spread through Europe under that name. Melons reached the New World with Columbus and continued moving west with Spanish settlers into California by 1683.
