Observation about total crop loss from frost.
Well, since literally all of the trees have ZERO crop, they seem to be putting on a tremendous amount of vegetative growth.
I cannot find a SINGLE apple or pear anywhere now. The few pears on my Bartlett that had begun to grow just bit have dropped, black in the centers just as all the rest were. I have about 2 dozen sour cherries handing on, and I found 3 peaches on one tree and two on another. Whoo hoo!
I guess that frees me from the majority of my spraying duties for the year, other than against disease and perhaps a late season oil spray to clean up the various nasties that might try to overwinter.
Without fruit, I realize they're just shade trees for the year, but the foliage on them looks particularly healthy. Maybe its just residual from last years ideal growing conditions with abundant rain, maybe its because they lost the fruit? Whatever the reason, I suspect that they will be loaded with buds for next year unless the summer turns hot and droughty.
