About Cantaloupe

Cantaloupe (muskmelon) is a sweet, fragrant summer melon that needs real heat and full sun to develop its sugar. Slip off the vine when ripe.

Start indoors 3-4 weeks before last frost or direct sow after frost in warm soil. Thin to 18-24 inches. Harvest when the melon slips easily from the vine with light pressure.
