Grow Bigger Tomatoes with Companion Planting
Growing tomatoes is relatively straightforward, but for those aiming for larger, juicier fruit this summer, a simple gardening technique can make a significant difference. The Royal Horticultural Society (RHS) highlights companion planting as a method where different plants are grown together to benefit one or both. Some plants confuse or act as decoys for pests, while others attract natural predators.
Positioning certain plants near tomatoes can promote healthier growth and improved fruit production. Conversely, unsuitable companions might jeopardize your entire crop. According to an expert at Obsessed Lawns, tomatoes thrive with companions like basil, marigolds, or nasturtiums.
Top Companion Plants for Tomatoes
These beneficial plants not only help repel pests but can also enhance the taste of your harvest. Basil is renowned for improving tomato flavour and is versatile in many dishes. Nasturtium effectively wards off whiteflies and aphids, common tomato pests during summer. Marigolds also deter harmful insects. Additionally, peppers, spinach, lettuce, and carrots make excellent companions, supporting robust tomato growth.
The RHS adds that companions can boost the health of neighbouring plants. For instance, parsley increases vigour in tomatoes and asparagus, while horseradish planted near potatoes strengthens them against disease.
Alternative Care Tips
If you opt not to use companion plants, regular disease monitoring is crucial. Alternatively, choose disease-resistant varieties like Crimson Crush. During the growing season, remember to remove side shoots to direct growth to the main plant. Neglecting this can result in a spindly plant with little fruit.
Watering Guidelines
Water tomato plants consistently to keep soil or compost evenly moist. Fluctuating moisture can cause fruit splitting or blossom end rot. Container-grown tomatoes dry out quickly, so water daily in hot weather. Curling leaves indicate water shortage, so monitor closely.
