Follow the advice on feeding, watering, mulching, and fruit-thinning given for apples seepp.296-297). In fall, remove mulches and rake up all fallen leaves, or mow over them so they are taken into the soil quickly to remove fungal spores. 

For the best size and quality of fruit, thinning is essential. Thin in two phases when fruitlets are the size of grapes, thin to one fruit per cluster and then later, when they are walnutsized, thin again to leave one fruit every 6 in (15 cm) approximately.

To sum up - it would seem that reduction of the on year crop by blossom or fruit thinning with growth regulators remains the most practical way of controlling biennial bearing in apples but we still need more reliable and consistent fruit thinning agents.

In the commercial production of fruit, the ability to control the number of fruit per tree is of great importance. Sometimes it is desirable to increase fruit set while at others it is imperative that fruit thinning be practiced. Chemical treatments have been devised to satisfy both needs. It is now common practice to use growth regulators to control fruit set as well as to influence the size, shape, and rate of maturation.
