First, I wish to thank those of you who came out and supported us and this beautiful park at our annual plant sale in May.  It was highly successful, and we appreciate all who attended.  I wish to also thank our military veterans who volunteered at the event and assisted our patrons with their purchases.

This summer has been a tale of two weather systems.  In June it was hot and dry.  So far July has been rainy and very humid.  Both conditions make for some challenges for our trees as well as ourselves.  No doubt you have seen (and felt) the arrival of mosquitoes and deer flies this season, which are thriving in these conditions.  Make sure you clean out bird baths and reduce standing water in gutters, drainage areas, and anything that can hold water long enough to allow mosquitoes to breed.  Mold spores will also thrive and those of us who are affected will be sneezing often. Consider using biological mosquito dunks in your birdbaths, catch basins and other areas that hold water.  They are safe for fish and wildlife but kill mosquito larvae.

The consistent cloudy and humid days will bring diseases to trees like sycamores and maples, along with many vegetables you may be trying to grow in your gardens.  There is not much you can do at this point if the weather does not improve.  It is best to rake up any diseased leaves that fall off the trees and either compost them, burn them or dispose them in the trash.  There are fungicides available but may be ineffective once the disease is within the plants or leaves of the trees.  Fungus and bacteria will be more aggressive so trees that have decay issues should be inspected for hazardous conditions.  Do not hesitate to prune off diseased or decayed limbs that have advanced decay.

One positive about this clammy weather is that some beneficial fungal diseases will appear and help control tree pests like gypsy moths and other caterpillar species that attack trees.

After the longest day of the year passes (June 20, 2021) the hours of daylight slowly decreases each day thereafter.  This signals trees to begin preparing for the fall and winter seasons.  Next year’s buds are set, and the trees are storing sugars within their roots and cells for the long winter nap that is coming.

Continue watering plants and trees if August and early September becomes hot and dry so the trees enter the fall season well hydrated, and you will be rewarded with better fall colors when the time comes.

I hope you have a great summer, and we intend to bring our summer concerts back next year once the pandemic is over, and we can all rejoin normal life in the park.
