I have was led to believe that when fruit trees get stressed they really blossom well the next time so there is plenty of seed to carry on if it dies.
I’m clueless about causes but have got round to inspecting my trees. To my interest, Fiesta has just one very small cluster of flowers and the rest of the tree is without flowers. Whatever affected your Fiesta, Beersmith, might just have had a similar effect on my tree?

Whatever affected your Fiesta, Beersmith, might just have had a similar effect on my tree?I'm in the east Midlands and my trees are in a sunny spot, and very much in the area of last year's record temperatures. So one possibility is that the variety is sensitive to heat. What part of the country are you based? If in a cooler area that avoided the 40 degrees C records we might need to think again but sensitivity to heat is one hypothesis.The effects of temperature on apples is an important research area. I went to Brogdale a few years back. They have an experimental area where average temperatures are raised by just one or two degrees on average. The key concern was that apple crops might be reduced if winters were too mild. A slightly different issue but clearly apples are not completely immune to temperatures.Thanks for your interest.
