is probably the most asked question we get.  One of the major reasons is due to our erratic spring freezes.  Depending on where the fruit bud is in its stage of development it can withstand as low as 10 degrees or may freeze at 29f.  Knowing the development stage and the allowable temperature will tell you what actions to take to try to prevent or minimize a crop loss.  The problem in the past has been knowing what the verbally described stage of development is.

apple blossom developmentThe other day I ran across this webpage that is  simple and spells (shows pictures) it out for us for each tree fruit.  It shows the temperature that will give a 10% loss at the particular stage of developments as well as the temperature that will induce a 90% or greater loss.

Take a few minutes to look at this simple webpage and then keep it bookmarked for future reference.
