Growing blueberries in containers is a game-changer for home gardeners. Whether you have limited backyard space or your native soil is too alkaline, pots give you total control over the acidic environment these “blue pearls” crave. However, picking the wrong container can lead to root rot or stunted growth.
This guide will walk you through everything you need to know to choose the perfect blueberry plant pots in 2026.
1. Size Matters: Don’t Cramp the Roots
Blueberries have shallow, spreading root systems. While a small starter plant looks fine in a 1-gallon pot, it won’t stay that way for long.
- Young Plants (1-2 years): Start with a 3-to-5-gallon container.
- Mature Plants: To ensure a heavy harvest, move up to a 15-to-20-gallon pot (approximately 18–20 inches in diameter).
- Depth: Aim for at least 12–16 inches deep.
Pro Tip: If you are growing “Top Hat” or “Peach Sorbet” (dwarf varieties), you can stick to a 10-gallon pot permanently.
2. Material Comparison: Which is Best?
The material of your pot affects moisture retention and soil temperature.
| Material | Pros | Cons |
|---|---|---|
| Resin/Plastic | Lightweight, retains moisture well, affordable. | Can overheat in direct summer sun. |
| Terra Cotta | Beautiful, breathable. | Dries out very fast; heavy; can crack in winter. |
| Fabric Grow Bags | Excellent drainage; prevents root circling via “air pruning.” | Needs more frequent watering; less aesthetic. |
| Glazed Ceramic | Heavy (won’t blow over), holds moisture. | Expensive and difficult to move. |
Our Recommendation: For the best growth, use high-quality fabric grow bags or light-colored resin pots to prevent the roots from cooking in the summer heat.
3. Drainage: The Non-Negotiable Factor
Blueberries love “moist but well-drained” soil. They hate “wet feet.” If water sits at the bottom of the pot, the roots will rot within weeks.
- Check the holes: Ensure there are multiple drainage holes at the bottom.
- Elevation: Use “pot feet” or bricks to lift the container off the ground. This allows water to flow out freely and prevents pests from hiding underneath.
4. Mobility and Aesthetics
A 20-gallon pot filled with damp acidic soil is heavy.
- Rolling Caddies: Consider placing your pots on a heavy-duty plant caddy so you can chase the sun or move the plants to a sheltered spot during extreme freezes.
- Color Choice: Light colors (tan, grey, white) reflect sunlight, keeping the root zone cool. Dark pots absorb heat, which can be detrimental in zones 7-9.
5. Summary Checklist for Your Purchase
Before you head to the garden center or order online, keep this checklist handy:
- Is it at least 15-20 gallons for a full-size bush?
- Does it have ample drainage holes?
- Is the material durable enough for 5+ years of use?
- Is it light-colored to prevent overheating?

Final Thought: The Soil Secret
Even with the perfect pot, blueberries will fail without acidic soil. Always fill your chosen pot with a mix specifically designed for acid-loving plants (like an azalea or camellia mix), or create your own using a 50/50 blend of peat moss and pine bark.
By following this guide, you’ll have a thriving, fruit-bearing blueberry bush that will provide sweet treats for years to come. Happy planting!
