Blueberries bring a delightful trio of benefits: they blossom in the spring, bear fruit in the summer, and show off vibrant fall foliage. These charming shrubs add beauty to your garden and also reliably deliver delicious berries year after year. Thanks to their manageable size, blueberry bushes are one of the easier edible perennials to grow, although they do grow at a slow to moderate pace.

However, when it comes to growing blueberries, it’s important to choose your plant neighbors wisely. While some plants can enhance their growth and boost your harvest, others can hinder progress by competing for nutrients or introducing diseases to your garden.

Choosing the wrong companions can make a big difference in your gardening success. Here’s a list of 15 plants you should avoid planting near your blueberry bushes to keep them thriving.

While peppers thrive in warmer soil, they are not suitable companions for blueberry bushes due to their differing soil pH needs. Peppers prefer less acidic soil, while blueberries thrive with this type of soil.

Tomatoes, like peppers, require a less acidic soil environment compared to blueberries. Since tomatoes are heavy feeders, they can deplete the soil of nutrients that blueberries need, potentially stunting their growth.

Brussels Sprouts

Brussels sprouts can be detrimental to blueberries as they absorb a lot of nitrogen, which blueberries also heavily depend on. Brussels sprouts prefer a more alkaline soil pH, which contrasts with blueberries’ acidic preference. This mismatch can lead to nutrient competition and poor growth for the blueberries.

Due to its vigorous growth and large nutrient uptake, broccoli competes with blueberry bushes for nutrients and water. Additionally, its preference for a slightly more alkaline soil can disrupt the acidic conditions needed by blueberries. Planting broccoli near blueberries can hinder the growth and fruiting of the bushes.

Cantaloupe’s extensive root system and preference for a neutral pH can disrupt the acidic soil environment needed by blueberries. This competition for nutrients and water, along with different soil pH needs, makes cantaloupe a poor companion for blueberries.

Watermelon, requiring a lot of space and nutrients, can overshadow and outcompete blueberries for essential resources. The vast difference in their growth requirements makes co-planting them problematic, often to the detriment of the blueberry bushes.
