How long do potted blueberry plants live?

Proper care ensures that potted blueberry plants can last for 15+ years. I've been growing container blueberries since 2018, which still produce a ton of berries. Their lifespan is primarily dependent on repotting every 5-7 years in a bigger container. Replacing the soil once a year will prevent nutrient depletion. Providing winter protection greatly extends their productivity.

Each year, I make sure to refresh 50% of soil with the same acidic blends. For most plants, I blend peat moss and pine bark fines for a proper texture. As you apply the fresh soil, you will see growth bursts afterwards. I test the pH level quarterly throughout the year to maintain an acceptable range, ideally between 4.0 and 5.0. This is particularly important for blueberries in containers compared to those in the ground.

Annual pruning retains structure and productivity. Remove branches that grow inward each spring. Always cut above outward-facing buds and at a 45-degree angle. Never remove more than one-third of the growth at a time. My bushes have significantly heavier harvests after proper thinning. They remain compact forms that are well-suited for containers.

The lifespan and fruiting life of blueberries can be increased by tracking environmental stressors. Protect from excessive afternoon sun in summer. If you experience a heat wave, use shade cloth. To prevent salinity buildup from irrigation, flush the soil once a quarter. These are all ways to improve the longevity of container-grown plants compared to ground-grown plants. My oldest continues to fruit at 9 years old.
