What to Grow in a Greenhouse in Summer

As the days lengthen and the warmth of summer fills the air, greenhouse gardening becomes an even more delightful pursuit for avid horticulturists. With the shelter and controlled environment a greenhouse provides, the possibilities for growing a wide variety of plants extend far beyond the limitations of outdoor gardening. If you’re a keen gardener in the UK wondering what to cultivate in your greenhouse during the summer months, you’ve come to the right place, on what to grow in your greenhouse in the summer months.

Vegetables and Fruits to Sow and Grow

In a greenhouse, you have the perfect conditions to nurture heat-loving vegetables and fruits that might struggle outdoors in the UK’s temperamental climate. Consider planting tomatoes, peppers, cucumbers, and aubergines. These sun-loving crops thrive in the warm, sheltered environment provided by a greenhouse. Opt for varieties bred for greenhouse cultivation for best results.

Tomatoes are a staple for many greenhouse gardeners. With a multitude of varieties to choose from, including cherry, beefsteak, and heirloom types, you can experiment with different Flavors and textures. Just remember to provide adequate support for your tomato plants as they grow, such as stakes or trellises, to prevent them from sprawling and ensure good air circulation to ward off diseases.

Cucumbers and peppers also flourish in greenhouse conditions. Plant them in well-draining soil and ensure they receive ample sunlight and consistent moisture. With proper care, you’ll soon be harvesting crisp cucumbers and vibrant peppers straight from your greenhouse, to have with a delicious summer BBQ.

For fruits, consider cultivating strawberries in hanging baskets or containers. These juicy delights thrive in the warmth of a greenhouse and can be grown vertically to save space. With regular watering and feeding, you’ll be rewarded with a bountiful crop of sweet strawberries throughout the summer.

Flowers for Greenhouse Beauty

While vegetables and fruits may take centre stage, don’t overlook the beauty and fragrance that flowers can bring to your greenhouse. In summer, you can fill your greenhouse with a riot of colours and scents by planting a variety of flowering plants.

Start with summer-blooming bulbs such as lilies, gladioli, and dahlias. These showy blooms add a touch of elegance to any greenhouse and come in a range of hues to suit your taste. Plant bulbs in pots or directly in the ground, ensuring they receive adequate sunlight and water for healthy growth.

Annuals like petunias, marigolds, and geraniums are also excellent choices for greenhouse cultivation. These prolific bloomers will provide a constant display of colour throughout the summer months, brightening up your greenhouse with their cheerful presence. Deadhead spent flowers regularly to encourage continuous blooming and remove any faded foliage to prevent disease.

Taking Care of Your Greenhouse Garden

To ensure your greenhouse garden thrives throughout the summer, it’s essential to provide proper care and maintenance. Here are some tips to keep your plants healthy and productive:

1. Watering: Check soil moisture regularly and water plants as needed, taking care not to overwater. A drip irrigation system can help maintain consistent moisture levels, especially during hot spells.

2. Ventilation: Proper airflow is crucial for preventing heat buildup and disease in your greenhouse. Open vents and doors during the day to allow fresh air to circulate and consider installing a fan for additional ventilation.

3. Pest Control: Keep an eye out for common greenhouse pests such as aphids, whiteflies, and spider mites. Regularly inspect your plants for signs of infestation and treat affected areas promptly with organic pest control methods or insecticidal soap.

4. Fertilization: Feed your plants regularly with a balanced fertilizer to promote healthy growth and abundant yields. Follow package instructions for application rates and frequency, and avoid overfertilizing, which can lead to nutrient imbalances.

With proper care and attention, your greenhouse garden will flourish throughout the summer months, providing you with a bounty of fresh produce and vibrant blooms to enjoy.
