How Do I Grow Courgettes In A Polytunnel?

Growing courgettes in a polytunnel can be an easy and rewarding way to add fresh and healthy produce to your diet. Here are some tips for growing courgettes in a polytunnel:

  1. Choose the right location: Courgettes prefer full sun and warm temperatures, so choose a spot in your polytunnel that gets at least 6-8 hours of direct sun per day. They also require well-drained soil with a pH between 6.0 and 7.0.

  2. Preparing the soil: Prior to planting, amend the soil with compost or well-rotted manure to improve fertility and add a slow-release fertilizer as well. To maintain good drainage and aeration, consider raised beds or containers.

  3. Starting the plants: You can start your courgette plants indoors about 4-6 weeks before your last frost date, or you can direct sow them in the polytunnel after the risk of frost has passed.

  4. Spacing and Trellising: When transplanting or direct sowing, space the plants about 3 feet apart in rows that are at least 4 feet apart. If the weather is warm and dry, you may need to water more frequently. Courgette plants will benefit from being trellised, this help keep the fruits off the ground and making it easier to harvest.

  5. Fertilizing: Feed the courgette plants regularly with a balanced fertilizer, side-dressing them every 4-6 weeks or according to the instructions on the fertilizer package.

  6. Pest and Disease control: Courgettes are susceptible to a number of pests and diseases, so be sure to keep an eye out for issues such as powdery mildew, mosaic virus, aphids and cucumber beetles. You can use an organic pest control method to keep them under control.

  7. Harvesting: Courgettes are best harvested when they are about 6-8 inches long and are still shiny. Continual harvesting will encourage the plant to produce more fruit. Be sure to check your plants regularly as they can grow quickly.
