Best Companion Plants for Arugula

1. Asparagus

Worst Companion Plants for Arugula

Despite the long list of good companion plants for arugula, a few plants should not be grown with arugula, as they may result in poor growth or increased pests or diseases.

1. Brassicas

Because arugula is a member of the brassica (cabbage) family, it should not be grown with other brassicas. A large swath of plants in the same family encourages the spread of shared diseases and pests. Similarly, avoid planting arugula where other brassicas grew the year before.

2. Nightshades

Tomatoes, peppers, eggplants, and potatoes prefer acidic soil (pH 5.5-6.5), while arugula thrives in neutral soil (pH 6.5-7). Although nightshades and arugula may not directly affect each other, these differing growing requirements mean they should occupy different beds.

3. Strawberries

Unfortunately, strawberries can impede the growth of arugula as well as other brassicas. But since strawberries are perennials, you may not want them in your vegetable garden anyway. Plant them instead in a perennial garden or in their own dedicated bed at the edge of the vegetable garden.

A flavorful, nutrient-dense salad green, arugula makes a wonderful addition to any spring vegetable garden. Try planting it near one or more of the companion plants listed above for a healthy, bountiful, flavorful crop, and enjoy home-grown salad all spring long – and maybe into summer!
