Our slow to start and fluctuating spring has earned the region an average of 82 growing degree days. The cool, overcast, damp days have given way to warmer than average temperatures but are forecasted to level out into average weather for the time of year. Soil temperatures have increased and are able to maintain proper levels for continual vegetative and root growth. Much of the northeast has received approximately 1 to 1.5 inches of rain, so newly planted trees should continue to be watered regularly. Extended floral blossoming continues and warming temperatures coax late bloomers out of their buds. However, it is not only plants that capitalize on spring weather, diseases get a boost from warmer, damper, sunnier days as well.
Many diseases are coming into their own in late spring as air and soil temperatures rise and days grow longer and sunnier. Due to complex life cycles, morphological stages and multiple hosts diseases will appear at different times of year on different plants, making identification and treatment tricky. Discussed below are some diseases currently showing up, this is by no means, an all inclusive list. Your arborist will be able to properly assess disease on your landscape and recommend treatments and/or preventative measures.
