Why winter lows in the 30s and summer highs in the 100s are perfect for our tree fruit trees.
After a long 9 months of work to produce a crop, the trees need 3 months of cold weather in the 30s and 40s to recharge. Between November and January we measure chill hours in our orchards. Chill hours are measured in the hours that the temperature is 45 degrees or lower. These chill hours are like sleep for the trees as they prepare for the next year’s crop. A total of 800-850 chill hours is the desired minimum.
During the summer months of steady weather, between 90 and 100 degrees, our trees are able to produce fruit at a consistent rate. These warm temperatures are the optimum amount of heat for our trees to thrive. Any cooler and our fruit would be smaller and less flavorful.
