But to use one example of my own -
most blueberry plants require X = number of chill hours. In other words, in a chilled dormant state in order to be vigorous.
A particular variety that I have grown for nearly 15 years now does not get the required chill time per season to be productive.
It is not a matter of being old stock that no longer produces because new plantings of the same variety and pruning have proven this to be a good producer over the years. Even the new plantings that may be 3 or 4 years old are no longer productive.
Therefore, they are of no benefit to me any more and I now have to replace them with another variety - one that requires less chill time and most likely a hybrid that has not really been a proven producer in this area.
I have actually been looking in a wholesalers catalog I get in the mail at blueberry varieties (as well as a couple more varieties of raspberry/blackberry) to extend the growing season.
I am surrounded by farmers and growers who measure their crops not so much as in acreage but in square miles.
Many are apple, peach, and pear growers. Again, these plants do require a dormant season.
Problem is, many are now blooming and budding way too early and the crop is being wiped out by a freeze or frost.
When they go through a cold spell and then the weather starts to really warm up, they believe it is time to start producing buds and blooms.
There are notable and large growers of Apples that supply the entire country with Virginia Apples - Mutsu, Granny Smith, Fuji, Yellow Delicious, Roma, Gala, Johnagold, and about 20 other varieties of apples.
One or two seasons spread out in sporadic years is not too great of a concern. But year after year is cause for concern, especially for early season bloomers. It is very difficult to find Mutsu sometimes on the east coast.
The same happens to my Walnut Trees. Folks will tell you the best Walnuts in the world are Black Walnuts and mine are outstanding! Huge flavor, sweet, and delicious. I have trees from 25 years old to nearly 200 years old still producing - and that is not an exaggeration! They start flowering in late April/Early May. A late frost/freeze in early May can wipe out an entire year's crop. My crops now come about every three years. Still able to load up several truck loads. But not near as much or as often.
That is what I am referring to as crops being decimated by the weather and seasons.
It is as if the chart that you would commonly see as "growing zones" or recommended zones to plant is actually changing.
As for the generations before ours, those so called "old timers" are still around and can offer even further insight to what has gone on and what has changed.
I help some of them when it is time to harvest and turn the fields, and so on. They are invaluable for their advice and instructions. They have helped me out immeasurably.
