Starting Honeydew Melons Indoors

In cities like Denver (Zone 5b), begin indoor honeydew melon seed starting between April 1 and April 30. This timeline ensures healthy seedlings ready for outdoor transplantation starting from mid-May to early June once the risk of frost has passed.

Transplanting Honeydew Melon Seedlings

Transplant honeydew melon seedlings outdoors from May 15 to June 1, ensuring the soil has warmed above 70°F consistently. Space the seedlings 24-36 inches apart in rows with at least 48 inches between rows for optimal growth.

General Care and Maintenance

Watering

  • Provide consistent and deep watering to maintain evenly moist soil. Colorado’s dry climate necessitates regular watering to prevent soil dryness.
  • Water at the base of plants to avoid leaf wetness, reducing the risk of fungal diseases.

Fertilizing

  • Apply a balanced fertilizer during planting and when the first melons start forming. Incorporating compost before planting can enhance soil fertility and structure.

Pest and Disease Management

  • Regularly monitor for common pests like aphids, cucumber beetles, and downy mildew. While Colorado has lower humidity, pest vigilance is essential.
  • Implement organic or integrated pest management methods to protect honeydew melon plants from pests and diseases.

Harvesting

  • Harvest honeydew melons when they turn a creamy yellow color and have a slightly waxy feel. Regular harvesting promotes continuous production and prevents overripening.

Honeydew Melons: Facts and Growing Tips

Honeydew Melons, part of the Cucurbitaceae family, are smooth-skinned melons with a sweet, juicy flesh. They are typically round or oval, with a pale green or yellow exterior and a sweet taste that makes them a popular snack and ingredient in fruit salads. Honeydew melons thrive in warm climates and require well-draining, fertile soil to flourish.

Before starting to grow it is important to take a step back and find the condition of the soil in your garden. The optimal soil is a blend that includes the mineral-rich dirt along with organic-rich organic matter that plants need to thrive.


In my garden I try to compost as much as possible, so I can mix in the nutrient-rich compost in my soil. I use both hot composting of food scraps and cold composting of all organic garden “waste”.
If you don’t have the time or space for composting, it is possible to get compost ready to use in garden centers and Community Composting.

If you are uncertain of the quality of your soil, you can get easy to use soil tests at Amazon for 17 dollars. Check latest prices here:Soil testing kit.

Also remember to check out how much sunlight your growing area gets, and that the rain drains well. If you treat your soil well and plan your crops according to your climate you will succeed with honeydew melons and any plant you want.

The satisfaction when you harvest your own honeydew melons is well worth the time you put in 🙂
