When to Prune Blueberries in Washington State?

General Guidelines

• In Washington state, the ideal time to prune blueberries is during the dormant season, which typically begins in late winter to early spring (February to March).
• Do not prune in the fall, as this can stimulate new growth that may not have enough time to harden off before winter, making the plant more susceptible to damage.

Pruning Considerations

• High-Bush Blueberries: Prune in late winter to early spring, before new growth begins.
• Rabbiteye Blueberries: Prune in late winter, about 4-6 weeks before the onset of growth.
• Half-High Blueberries: Prune in late winter to early spring, taking care not to remove more than 20% of the plant’s total foliage.

Pruning Techniques

Remove Dead, Diseased, or Damaged Wood: Identify and remove any dead, diseased, or damaged branches to prevent the spread of disease and promote healthy growth.

Cut Back Overgrown Branches: Trim back overgrown branches to encourage new growth and improve air circulation.

Cut Back Tips of Young Plants: For young blueberry plants, cut back the tips to encourage branching and promote a more balanced plant structure.

Make Clean Cuts: Use clean, sharp pruning tools and make cuts at a 45-degree angle to promote healing and prevent water from entering the cut.

Timing of Pruning

Conclusion

Pruning blueberries in Washington state is a crucial aspect of maintaining a healthy and productive blueberry patch. By pruning during the dormant season and following the guidelines outlined above, you’ll be able to promote fruiting, improve air circulation, and maintain the overall shape of your plants. Remember to make clean cuts, remove dead, diseased, or damaged wood, and prune judiciously to avoid over-pruning. Happy pruning!
