A typical Yellow Bellflower orchard in the Pajaro Valley. These trees show the results of heavy crop production. Props from the previous year still remain in place in the orchard. 6. Pruning Trees properly cared for during their formative period should be well shaped and mechanically able to support heavy loads. Although some varieties, such as Rome Beauty, Jonathan, and Wagener, produce much of their fruit on the tips of last year's branches and although on the Pa- cific Coast a number of varieties may produce fruit laterally on one-year twigs, most of the crop is produced terminally on short branches or on spurs originating from wood 2 years old or older. These spurs normally begin to form after 3 to 5 years, or when the young tree naturally tends to slacken its vegetative growth. The primary consideration, therefore, in pruning bearing trees is to maintain a proper balance between vegetative growth and fruit production. Excessive growth by the young tree is usually pro- duced at the expense of fruit production, while overbearing is accompanied by less growth and if continued may destroy vigor. The ideal condition during the years of maturity is for the trees to make 6 to 10 inches of new growth each year, and thus increase and maintain the fruit- ing area while producing large but not excessive annual crops. With most trees that have received reg- ular pruning previously, there is little necessity for more than a light annual thinning and cutting back of the upper- most branches to laterals. This will pre- vent the tree from getting too high for economical spraying and picking opera- tions. The center of the tree should be kept fairly open. Where this has been neg- lected in past years, it is better to thin out surplus branches over a period of two seasons rather than upset the balance of the tree by removing too much wood in any one year. Light crops and a large amount of vegetative growth would indicate that previous pruning had been too severe. SECTION IV-Page 5
