Charles from Americanlife365. Many viewers asked me why there are fewer fruits on their trees. The tree bears a lot of fruit a year, but not much another year. Maybe you think of the so-called "big year" or "small year". It is actually wrong. One of the reasons is closely related to the 'chill hours' your tree gets. What is the conecpt of chill hours? Cold time is the total time in winter when the temperature is below 45 degrees Fahrenheit. When it is cold, the trees are dormant, just like a person sleeping at night. After dormancy, the tree will wake up to sprout and bloom. If the temperature is too low when the tree starts to sprout, the buds will be injured or frozen.
Their buds or flowers will be damaged. Later on, there will be fewer and fewer fruits, or even none. So if there is a late start spring or frozen day in early spring, There will be bad year for the fruit tree to produce more fruits. It will damage the buds. That year becomes a bad year for a tree to bear fruits. During the dormant period, the roots of the tree grow vigorously. Just like babies get healthier and longer when they have a good sleep. Many people mistakenly believe that from Fall, trees in winter will not grow. Actually trees grow big in roots in winter. Does this mean that there is less chill hours, warmer temperatures are good for trees to produce more? Not really.
If too soon to warm temperature, trees do not have enough chill hours. The tree roots do not grow well and cannot produce more fruits. Tree relys on its roots to get more nutrients. Less roots, less nutrients and less fruits. Therefore, if you buy a tree, be sure to pay attention to the chill hours.
The chill hours for every fruit tree is different. The chill hours for different location is different too.
If your location does not have enough chill hours or too much chill hours for a fruit tree, It will be difficult for the tree to bear more fruit. I remember when  I bought my fruit tree, I paid attention to the chill hours. That is why my fruit trees produce aboundant of fruit every year. Make sure that do not lose at the starting line. Calculate the total of chill hours to ensure enough but not too much. Let me share some information on chill hours for most of  fruit trees. 
Chill hours 0-300: the fruit trees are figs, berries, grapes, pomegranates
Chill hours 300-800: the fruit trees are: apples, apricots, nectarines, peaches, pears, plums and nuts.
Most of fruit trees are good in this range. We are in this chill hour zone. That is why our fruit trees bear a lot of fruit. Abounant. You can find your chill hour zone in your area from Agriculture Department. You just can not buy whatever fruit tree you want. You must make sure the chill hours of a tree is right in your chill hour zone. We have hundreds of videos in many aspects of  American Life.
