Pruning and training, fertilizing, thinning - plant material, tree pruning, growth inhibitors, fertilization - causes and countermeasures for unsatisfactory flower formation - fruit set issues and the possibilities/effects of fruit thinning. Fruit trees bear fruit most consistently when their growth is properly managed and timely thinning sufficiently reduces an excessive fruit set. This also ensures that fruit quality is not compromised. Numerous illustrations, photos, and years of experimental results deepen knowledge and encourage rethinking cherished habits in favor of better cultivation success and greater environmental protection.
