How to prune mature blueberry trees? Pruning methods and technical key points
How to prune mature blueberry trees? Please give an introduction. After strawberry plants reach maturity, the inner canopy tends to become congested and the crown is relatively tall, so pruning at this time is mainly to control tree height and improve light conditions; pruning is mainly thinning out branches, removing overly dense branches, thin and weak branches, diseased and pest-infested branches, and suckers produced by the root system. For trees with a more spreading growth habit, when thinning branches remove weak branches and keep strong ones; for upright varieties, remove the central leader and open up the top, and keep moderate branches. The best fruiting age for large branches is 5 to 6 years, and beyond that they should be renewed by cutting back. Weak small branches can be pruned by the method of removing flower buds to make them grow stronger.
