When planting blueberry bushes, spacing is a critical factor that directly impacts the health, growth, and productivity of your plants. Blueberries are long-lived perennials that can grow several feet tall and wide, so giving them enough space ensures they have room to expand, receive adequate sunlight, and benefit from proper air circulation. This helps minimize disease, optimize fruit production, and makes it easier to maintain the plants as they mature.
The ideal planting distance between blueberry bushes depends on the variety you're growing, the size of your garden, and whether you're planting in rows, clusters, or containers. Here's a detailed guide on how far apart to plant blueberry bushes for optimal growth and fruiting.
1. General Guidelines for Spacing
In most home gardens, blueberries are planted either in rows or as individual plants. As a general rule of thumb, blueberry bushes should be spaced at least 4-5 feet apart. This allows each plant to spread its roots and grow to its full width without crowding neighboring bushes. When planted too close together, blueberry bushes can compete for water, nutrients, and sunlight, which can stunt their growth and reduce fruit production.
- 4-5 feet apart between plants is the standard spacing for highbush blueberry varieties, which are the most common type grown in home gardens. Highbush blueberries can grow up to 6-8 feet tall and wide, making this spacing essential for healthy plant development.
- 2-3 feet apart between plants is appropriate for lowbush blueberry varieties, which are smaller, spreading plants that stay closer to the ground. Lowbush blueberries are typically grown in cooler climates and are often used for ground cover or in smaller garden spaces.
2. Spacing Between Rows
If you’re planting multiple rows of blueberry bushes, it's equally important to leave enough space between each row to allow for easy access to the plants for maintenance, pruning, and harvesting. The recommended distance between rows is 8-10 feet. This space accommodates the mature size of the bushes and provides ample room for you to walk between the rows without damaging the plants.
- For commercial growers or those with large blueberry patches, this wider row spacing also allows room for equipment like wheelbarrows or irrigation systems to be used without disturbing the plants.
3. Spacing for Different Blueberry Varieties
Different blueberry varieties have varying growth habits, which can affect how far apart they should be planted. Understanding the growth patterns of the variety you're growing will help you determine the best spacing.
- Highbush Blueberries: These are the most commonly grown type and include both northern and southern highbush varieties. They grow upright and can reach 6-8 feet in height and width. Highbush blueberries should be planted 4-6 feet apart for optimal growth and air circulation.
- Rabbiteye Blueberries: Native to the southeastern United States, rabbiteye blueberries tend to grow taller than highbush varieties, sometimes reaching up to 10 feet. Because of their size, it's best to plant rabbiteye varieties at least 6 feet apart to give them enough room to grow. Rabbiteye blueberries are often planted in warmer regions where they thrive.
- Lowbush Blueberries: These are shorter, ground-hugging plants that spread by underground rhizomes. They only grow about 1-2 feet tall and wide, so they can be planted closer together. Space lowbush blueberry plants about 2-3 feet apart for best results.
4. Benefits of Proper Spacing
Planting blueberry bushes at the right distance offers several important benefits:
- Better Air Circulation: Proper spacing improves air flow between the plants, reducing the risk of fungal diseases like powdery mildew and botrytis, which thrive in humid, poorly ventilated conditions. Good air circulation is crucial for the overall health of the plants.
- Maximized Sunlight Exposure: Blueberries need full sun—at least 6-8 hours of sunlight per day—to produce the best-quality fruit. When bushes are spaced too closely, they can shade each other, leading to reduced fruit production. Adequate spacing ensures each plant receives sufficient sunlight for photosynthesis and berry development.
- Easier Maintenance and Harvesting: With proper spacing, you'll have enough room to prune, fertilize, water, and harvest your blueberry bushes without damaging the plants. You’ll also have easier access to the fruit when it’s time to pick, as you won’t have to navigate through overgrown branches or crowded bushes.
- Healthy Root Development: Blueberry bushes have relatively shallow root systems, and planting them too close together can result in competition for water and nutrients. Proper spacing allows the roots to spread out and absorb moisture and nutrients more efficiently, promoting stronger growth and larger yields.
5. Spacing in Containers
If you’re growing blueberries in containers, the spacing recommendations change slightly. Blueberry bushes grown in containers need ample room to spread their roots, but the size of the container limits how far apart the plants can be. Here are some container guidelines:
- Use a 12-16 inch diameter container for a single highbush blueberry plant. The container should have good drainage and be filled with an acidic potting mix designed for acid-loving plants like blueberries.
- Keep container-grown blueberry plants spaced at least 3-4 feet apart to prevent overcrowding and ensure good air circulation. Even though the plants are contained, they still need enough space to grow without competing with other plants.
6. Fertilizing Blueberry Bushes After Planting
After planting your blueberry bushes, proper fertilization is key to helping them establish strong roots and grow vigorously. Blueberries are heavy feeders and benefit from an organic fertilizer that supports their need for acidic soil conditions. BigAss Berries fertilizer is an excellent choice for blueberries because it provides the essential nutrients the plants need to thrive while maintaining the acidic pH required for healthy growth.
- For blueberries planted in the ground, apply 1 scoop (1 tbsp or 15 ml) of BigAss Berries per square foot of garden bed or planting area.
- For container-grown blueberries, use half a scoop (1-2 tsp or 5-10 ml) for an 8” container, 1 scoop (1 tbsp or 15 ml) for a 12” container, and 1.5 scoops (1.5 tbsp or 22.5 ml) for a 16” container.
Apply fertilizer in early spring, and repeat every 6-8 weeks during the growing season to ensure consistent growth and fruit production. Water the plants thoroughly after each application to help the nutrients reach the root zone.
Conclusion
Proper spacing is essential when planting blueberry bushes, as it impacts everything from plant health to fruit yield. For highbush and rabbiteye varieties, space the plants 4-6 feet apart and leave 8-10 feet between rows. Lowbush blueberries can be planted closer together, with 2-3 feet between plants. By giving your blueberry bushes enough room to grow, you’ll encourage healthy development, better air circulation, and easier access for maintenance and harvesting. Combine this with regular fertilization using BigAss Berries fertilizer, and you’ll be well on your way to growing productive, long-lasting blueberry bushes.
