Can You Plant Garlic, Blackberries, and Nasturtiums Together?

Companion planting is a time-honored gardening technique that maximizes plant health and yield by strategically pairing plants. In this article, we’ll explore whether garlic, blackberries, and nasturtiums can be successfully grown together, examining their compatibility and offering practical tips for gardeners.

Compatibility Analysis

Can garlic, blackberries, and nasturtiums be planted together? Yes, they can be grown together, but with some considerations. These plants can complement each other in a garden due to their distinct growth habits and beneficial properties.

Why They Work Together

• Pest Control: Garlic acts as a natural pest repellent due to its strong smell, which can deter pests that might otherwise target blackberries. Nasturtiums are known to attract beneficial insects, such as pollinators, and can serve as a trap crop for aphids, drawing them away from the blackberries.

• Growth Requirements: While these plants have different growth requirements, they can be managed with careful planning. Garlic prefers full sun and well-drained soil, blackberries thrive in full sun with slightly acidic soil, and nasturtiums can tolerate partial shade, making them versatile companions.

• Nutrient Needs: Garlic and blackberries have different nutrient needs, minimizing competition. Garlic’s shallow roots won’t interfere much with the deeper roots of blackberries, while nasturtiums can grow in poorer soils and help fix nitrogen.
