Apple trees surrounded by flowers are protected from pests

A new study in England’s green apple groves shows that insects like ladybugs and hoverflies help with apple pest control. Researchers discovered that planting wildflower borders around plants provides a natural home for beneficial insects. These helpful predators target pests that would otherwise damage the apples by threatening the crop’s health and economic value.

Apple pest control using wildflowers

Researchers from the University of Reading analyzed this innovative approach to pest management alongside five dessert apple orchards. Orchards adorned with flower margins saw a drastic reduction in fruit damage.

The study carefully chose wide, mature wildflower margins over five meters. The researchers mixed grasses and flowers to feed predatory insects all year. This long-term commitment to establishing diverse predatory insect communities has proven to be significantly effective.

In orchards with flower borders, pests affected only 48% of trees, compared to 80% in orchards without them. Flower margins helped control aphids and significantly cut fruit damage on infested trees.

Apples near flower borders were over a third less likely to be damaged, even at peak aphid times. This protection reached up to 50 meters into the orchard from the flower areas.

A simple solution for sustainable farming

In 2020, the UK produced 200,000 tons of dessert apples worth roughly $200 million. The study suggests flower margins could boost the harvest of premium apples by up to 2,420 kg per hectare (6.9%) by reducing pests.

The study emphasizes the effectiveness of simple conservation measures. Creating wildflower areas along orchard borders has the potential to significantly reduce pesticide use. This approach benefits pollinators and other helpful insects, promoting sustainable agricultural practices.

Broader implications

Charlotte Howard, the study’s lead author from the University of Reading, emphasizes the broader benefits of this approach. “By looking after our creepy crawlies, we can take better care of our apples,” Howard explains.

Planting flower margins is not just about enhancing apple quality; it represents a sustainable farming practice that reduces dependence on harmful insecticides, ultimately leading to healthier, more eco-friendly British produce in our supermarkets.

A consortium of researchers and agricultural stakeholders, including NIAB East Malling, Cranfield University, Syngenta, Avalon Produce, Worldwide Fruit, and the UK Centre for Ecology and Hydrology, joined forces for this study. Their work aims for a sustainable and more productive agricultural future, not just in the UK, but globally.

More about flower borders

As discussed above, flower borders are not just a way to add beauty and color to gardens; they also play a crucial role in attracting beneficial insects, providing habitat, and enhancing the overall biodiversity of an area.

Whether it’s a small garden patch or a sprawling landscape, incorporating flower borders can transform a plain space into a vibrant and lively part of your outdoor living area.

Designing your lower border

Choosing the right plants

When designing a flower border, selecting the right mix of plants is essential. Consider plants that bloom at different times of the year to ensure a continuous display of colors. Incorporate a variety of heights, textures, and colors to create a visually appealing border. Don’t forget to include perennial plants for longevity and annuals for bold, season-long color.

Soil preparation and planting

Preparing the soil is a critical step in establishing a successful flower border. Enrich the soil with compost to improve fertility and drainage. Arrange your plants while they are still in their pots to visualize how they will look together. Remember to consider their mature sizes to prevent overcrowding. Planting in staggered rows can create a fuller and more natural appearance.

Maintenance tips for flower borders

Watering and feeding

Regular watering is key, especially during dry spells. However, be mindful not to overwater, as this can lead to root rot. Feeding your plants with a balanced fertilizer in the spring will support their growth and flowering.

Pruning and deadheading

Pruning and deadheading spent flowers encourage plants to produce more blooms and maintain a tidy appearance. Some perennials may benefit from being cut back in late autumn or early spring, depending on their specific needs.

Mulching and weed control

Applying a layer of mulch not only helps retain soil moisture but also suppresses weeds and adds a finished look to the border. Keep an eye out for weeds and remove them promptly to prevent them from competing with your flowers for nutrients and water.

Ecological impact of flower borders

Beyond their aesthetic appeal, flower borders serve an important ecological function by supporting pollinators like bees, butterflies, and birds. Choosing native plants can enhance this benefit, as they are adapted to local conditions and provide the most suitable resources for native wildlife.

Flower borders are a dynamic element that brings life, color, and biodiversity to gardens. By carefully planning, planting, and maintaining your flower border, you can enjoy a beautiful and beneficial feature that enhances your outdoor space and supports the environment.

Whether you’re a seasoned gardener or a beginner, the creation of a flower border is a rewarding project that yields long-term rewards.

The study was published in the journal Journal of Applied Ecology.
