poor fruit set on Blueberry
Quick answer
If your Blueberry has poor fruit set, the most likely cause is: While many blueberry varieties are self-pollinating, they produce significantly larger and more abundant berries when cross-pollinated. Balconies often lack sufficient pollinator traffic (bees).
Start here:
- 1. Hand-pollinate by gently shaking the flowering branches daily or using a small electric toothbrush vibrating against the stem to release pollen.
- 2. Plant a second, different blueberry variety that blooms at the same time to enable cross-pollination.
