Cantaloupes take some space to grow and vine, so leave enough room for them to spread. Grow cantaloupe in rows spaced 3-4' apart or in "hills" with groups of 2 or 3 plants per "hill". Cantaloupes can also be trained on a trellis or fence to save space. Cantaloupes need a constant supply of water, and particular attention should be paid during summer dry spells. They need to ripen fully on the vine; they do not ripen well after they are harvested. Cantaloupes develop a wonderful fragrance when they are ready to pick; the fruit should slip easily from the vine and the blossom end should feel soft to the touch.
Melons: Honey Dew
When growing honey dew melons, it's important to keep the weeds under control during the growing season as they compete with plants for water, space and nutrients. Honey dews have a shallow root system, so mulches help retain soil moisture and maintain even soil temperatures. Keep plants well-watered during the growing season, especially during dry spells. Honey dew melons are ripe when the skin turns to a creamy yellow color and the blossom end is slightly soft.
