How to grow: Melons
Pest management: Cantaloupe cultural tips, pests, and diseases
When to plant: May–June. For best results, wait until soil is well warmed up in the spring. Start melon seeds indoors in April, 4-5 weeks before transplanting.
Harvest window: July-October, depending on variety
- Melons require a soil temperature of about 70 degrees to germinate, so a plant heat mat is often necessary if starting seeds in pots.
- Melons need full sun and high temperatures.
- Black plastic or black landscaping fabric can be used to keep the soil warm and weed free.
- Cover the plants with floating row covers to keep them warm and protected from pests. Remove the row covers when the plants start to blossom.
- Encourage bees for best pollination or hand pollinate.
- Provide an A-frame trellis or other type of structure to save garden space. To support hanging fruits, make a 'melon sling' made from soft material.
- Protect ripening melons that are on the ground by placing them on a board, tile, or other material.
Harvesting and storage:
- When mature, cantaloupes and muskmelons will smell fragrant and will detach easily ('slip') from the vine. Honeydew melons don't slip, but the color of their skin will change and will become waxy.
- Melons will soften after picking but will not increase in sweetness.
- Melons are best stored at 36-41°F and can last 12-15 days depending on the variety.
