The pruning of the blueberry is very simple. It consists in periodically cleaning the shrubs to keep them vigorous and fruitful.
The best time to prune blueberries is at the end of winter and early spring. February-March is usually the best time.
Important: A branch does not produce more than 3 or 4 years in a row, and each branch produces only on 2-year-old or previous year’s wood.
Note also that the most vigorous stems, generally growing from the base, are the ones that will give the best blueberries. It is then advisable to prune the branches when they no longer produce.
You will therefore prune the branches older than 3 years.
You should also remove the weakest branches.
Finally, remove the dead wood and let the maximum amount of light into the heart of the blueberry.
The blueberry appreciates cool soils and should be watered regularly in case of drought or strong heat.
