Let's delve deeper into the world of herbs, fruit, and flowering companions for blueberries.

Herbs as Companions

Herbs are excellent companions for blueberries, as they attract pollinators, repel pests, and enhance soil health. Borage, thyme, sage, and dill are particularly appropriate for companion planting with blueberries, offering various benefits to your blueberry bushes.

Borage, for example, is an annual herb that attracts pollinators, suppresses weeds, and prevents pests and diseases, making it a beneficial companion plant for blueberries. Thyme acts as a ground cover, protecting blueberries while repelling pests, thanks to its strong aroma.

Nightshades, including potatoes, tomatoes, and eggplants, should not be planted near blueberries due to their different soil pH requirements. These plants prefer a higher soil pH, which is not suitable for blueberries and can hinder their growth.

By avoiding nightshades when companion planting with blueberries, you can ensure that your blueberry bushes receive the appropriate soil conditions and nutrients they need to thrive.

Melons, such as watermelons, cantaloupes, and honeydew melons, should not be planted near blueberry bushes due to their different nutrient requirements and soil pH levels. These plants have specific growing conditions that are not compatible with blueberries and can negatively impact their growth and fruit production.
