Tracking Chill Hours
Fruit trees need a certain amount of "chill hours" in winter to produce fruit the next season. In cold winter areas, it's not an issue, but in mild winter locations such as our region, it can be the difference between a good harvest and a poor one.

Chill hours begin to accumulate at temperatures below 60F, so you'd think we'd have no problem getting high numbers. However, temperatures above 65F cancel out the already accumulated chill hours, so each day is a seesaw of adding to and reducing the final total. Coastal areas can count on at least 100-200 of chill hours each winter; inland valleys can hope for 300-500.

Sunset magazine suggests growing "low chill requirement" fruit tree varieties, those that grow well with a minimum of chill hours, in our region. Some good bets include apricots ('Royal', 'Katy', 'Gold Kist'), nectarines ('Desert Delight', 'Goldmine', 'Panamint', 'Snow Queen'), peaches ('Babcock', 'Bonita', 'Mid-Pride', 'Red Baron', 'Santa Barbara'), and plums ('Beauty', 'Burgundy', 'Satsuma', 'Weeping Santa Rosa'). Check local nurseries, Web sites, and catalogs for these varieties.
