Development does not occur at this time unless the temperature is above a minimum threshold value (base temperature). A base temperature of 50 degrees Fahrenheit is considered acceptable for all plants and insects.
Using phenology research, we can predict approximate bloom times and pest emergence with a reasonable degree of accuracy. Here is where we were as of this writing:
