A slow spring and critical temperatures

New raspberry and blackberry leaves

Last year my three exclamation point spring post came on March 26 --- the plant world had awakened, with peaches and dandelions in bloom and blackberry and pear leaves unfurling.  This year, we're at least a week behind...which is a good thing.

A few of our fruit trees --- the oldest peach, for sure, but also maybe the younger peach, nectarine, and cherry --- are old enough to set fruit, but only if a hard spring freeze doesn't nip their flowers.  Each stage in the bud-opening process has its critical temperature, below which the bud will be too damaged to set fruit.  For peaches, these temperatures are (for 10% and 90% kill, respectively):

In the spring, we gardeners tend to get antsy and want everything to happen now, but a chilly winter slows things down and may mean more food in the long run.  Here's a table of critical temperatures for most of the common fruits.  Don't forget to keep your eye on the weather forecast once your fruit trees begin to bloom!
