How to Grow Seedless Cantaloupe

Grow seedless cantaloupes in proximity to seeded cantaloupes. Cantaloupes are related to watermelons and grow in a similar way. Technically, there are no such things as seedless cantaloupes, just cantaloupes with very low seed counts; these are called triploid cantaloupes. Seeded cantaloupes are called diploid cantaloupes. For triploid cantaloupes to grow, they need to be close to diploid cantaloupes, which pollinate them to produce fruit. Additionally, the ground temperature must be above 70 degrees Fahrenheit.

Instructions

    • 1

      Till the first six inches of soil with a tiller or hoe and form a 4-by-4-foot mound approximately four inches high. Locate the mound six feet away from any other plant in your garden, since cantaloupe vines tend to spread out.

      Use your finger and poke approximately eight evenly spaced holes in the mound, the holes should be about half an inch deep. Drop a seed in each hole, alternating triploid and diploid seeds, and cover them with loose soil. Water the mound. You should see seedlings start to grow in about 10 days.

      Water the cantaloupes to give them a half an inch of water per week. Do not over water the cantaloupes, since that can damage the root system. When the cantaloupes begin to grow, place mulch underneath them to prevent rotting. When the fruits have established, reduce the amount of watering to approximately once every 10 days; too much watering at this stage causes the fruits to lose sweetness.
