Can I grow Melons in my Polytunnel?

Updated: May 16, 2023

Yes, it is possible to grow melons in a polytunnel. Melons are a warm-loving crop that can be grown successfully in a controlled environment such as a polytunnel. However, growing melons in a polytunnel can be a bit more challenging than other crops due to the melon's need for pollination and the large amount of space and support they require. Here are some tips on how to grow melons in a polytunnel:

  1. Start seeds indoors 6-8 weeks before the last frost date in your area. Use seed trays or pots and a good seed compost.

  2. Transplant seedlings into the polytunnel when they are big enough to handle. Space the plants 3-4 feet apart.

  3. Keep soil consistently moist, but not waterlogged. Melons prefer a pH between 6 and 7.

  4. Melons need a lot of space to grow and will require support as they get bigger, using a trellis or a vertical growing method is ideal to save space.

  5. Melons require high temperatures and high humidity, so a polytunnel is an ideal growing environment. Aim to maintain a daytime temperature of around 75-80°F and a nighttime temperature of around 60-65°F.

  6. Provide adequate light. Melon plants require at least 8 hours of sunlight per day.

  7. Fertilize melons regularly throughout the growing season with a balanced water-soluble fertilizer.

  8. Melons will need to be pollinated by hand or with the help of pollinators like bees, as they typically have separate male and female flowers.

  9. Melons take around 70-80 days to reach maturity from transplant. Watch for pests and disease and treat as necessary.

  10. Harvest melons when they are fully ripe, this is when the fruit will have reached its full size and color.

Keep in mind that melons are heavy feeders and space-consuming crop, and in a polytunnel space is limited. In a polytunnel, it's ideal to grow smaller varieties of melons like personal-size or mini-melon varieties that are more adaptable to the limited space.
