Cantaloupe / Muskmelon is a warm-season fruiting crop in the Cucurbitaceae family, grown either from a direct sowing or from transplants. It wants full sun (six or more hours of direct light) and steady, even moisture. From sowing to first pick is about 70–90 days. It is killed by frost, so nothing goes outside until the danger has passed and the soil has warmed.

Grower’s note: Needs 70-90 warm days - start indoors in paper pots in short-season areas. Ripe when the fruit slips from the vine with a light tug and smells sweet at the blossom end. Ease off water as fruit ripens for sugar.

Sowing

Sow about 1″ deep, into soil between 70–95°F — germination is quickest near 85°F. It comes up fast (4–10 days). For an early crop, start seed indoors about 3 weeks before your last spring frost and grow it under bright light.

Spacing & layout

Give each plant about 24″ along the row with roughly 60″ between rows. On a square-foot grid that is one plant per 4 square feet. Allow at least 18″ of loose, workable soil for the roots. It grows well in containers at least 18″ deep.

Fitting it to your season

Cantaloupe / Muskmelon needs roughly 70–90 frost-free days to crop. Where the season is shorter than that, start it indoors and choose the earliest-maturing varieties, or grow it in a container you can move under cover on cold nights. In long, hot-summer regions it can often be planted twice — once in spring and again in mid-to-late summer for a fall harvest.
