Culture.—Orchards are commonly cultivated the first half ofthe summer with cUsk harrows and other harrows. Then a wintercover crop is grown to be worked into the soil in spring. This greenmanure may be turned under by the only plowing given the orchardeach year. In the irrigated orchards the dust mulch is re-estab-lished after each watering (Fig. 196). Cultivation is abandoned or. Fig. 196.—A (.alifornia orange grove showing style of pruning trees and showing theirrigation furrows.

Harvesting and Marketing.—In California the Valencias () are picked from June to October; navels from November toApril, and seedlings in Spring. Most of the Florida crop is movedfrom October to May or June. Figure 197 shows an orange pickingscene in California. The bulk of the orange crop in America is handled through largeassociations that have central packing houses and market onlywell graded and wrapped fruits (Fig. 198).
