Blueberry Companion Plants: A Guide to Healthier, More Productive Bushes
Introduction
Companion planting is a gardening technique that involves growing specific plants near each other to enhance their growth and well-being. For blueberry bushes, selecting the right companion plants can provide numerous benefits, such as attracting pollinators, improving soil moisture, and supplying essential nutrients like nitrogen.
Benefits of Companion Planting for Blueberry Plants
- Increased pollination: Companion plants that attract bees and other pollinators, such as mint and bee balm, can help increase fruit production by ensuring adequate pollination.
- Improved soil moisture: Plants like ferns and strawberries have shallow root systems that help retain moisture in the soil, which is crucial for blueberry bushes that prefer moist conditions.
- Nutrient provision: Certain companion plants, such as legumes and clover, can fix nitrogen from the air and make it available to neighboring plants, including blueberries. This can lead to improved plant growth and yield.
- Pest deterrence: Aromatic herbs like mint and basil emit strong scents that repel common garden pests, such as aphids and blueberry maggots, protecting blueberry bushes from damage.
Choosing the Right Companion Plants
When selecting companion plants for your blueberry bushes, consider the following factors:
- Soil compatibility: Blueberries prefer acidic, well-draining soil. Choose companion plants that also thrive in these conditions, such as heather, rhododendrons, and cranberries.
- Nutrient needs: Avoid companion plants that compete heavily for nutrients, as this can stunt the growth of your blueberries. Instead, opt for plants that have different nutrient requirements or that can provide nutrients to the soil, such as legumes and cover crops.
- Growth habits: Consider the size and growth pattern of companion plants to ensure they do not shade or overcrowd your blueberry bushes. Groundcover plants like thyme and chives can be particularly beneficial, as they help retain moisture and suppress weeds without competing for sunlight.

Plants to Avoid Growing with Blueberries
While many plants can benefit blueberry bushes, there are a few species that should be avoided:
- Nightshades (e.g., tomatoes, peppers, eggplants): These plants have different soil pH preferences and can compete for nutrients.
- Brassicas (e.g., broccoli, cabbage, kale): These heavy feeders can deplete the soil of nutrients and water, harming blueberry bushes.
- Grasses: Ornamental grasses can spread aggressively, crowding out blueberry plants and stealing their resources.
Additional Tips for Growing Healthy Blueberries
- Site selection: Choose a planting site that receives full sun for at least six hours per day and has well-drained, acidic soil.
- Soil preparation: Amend the soil with organic matter, such as compost or peat moss, to improve drainage and fertility.
- Planting: Dig a hole twice the width of the root ball and just as deep. Set the blueberry plant in the hole and backfill with soil, tamping down gently to remove air pockets.
- Mulching: Spread a layer of organic mulch around your blueberry bushes to retain moisture, suppress weeds, and regulate soil temperature.
- Watering: Water your blueberry bushes deeply and regularly, especially during hot, dry weather. Avoid overwatering, as soggy soil can lead to root rot.
- Fertilizing: Fertilize your blueberry bushes annually with a balanced fertilizer designed for acid-loving plants.
- Pruning: Prune your blueberry bushes regularly to remove dead or diseased branches, encourage new growth, and improve fruit production.
By incorporating companion plants into your blueberry garden and following these additional tips, you can create a thriving environment that promotes healthy plant growth and abundant fruit production.
