The positive side of cold weather is that fruit trees native to colder climates, such as cherries and blueberries, may get the chill hours they need to produce good fruit. Going dormant saves energy which can then go into fruit development. No need to protect them on cold nights. Knowing the native habitat of your plants will guide you in caring for them. Mimicking the success of nature leads to greater success in your own garden.
Learn more about chill hours on the UC Fruit & Nut Information website. UC has historical chill hours available for many locations in California, however, Gilroy is the only location located in Santa Clara County. For county locations closer to the Bay, the Union City station may be more applicable (or view a map of all station locations).
