Climate change impact on WILD crafting and growing medicinal plants

Reflecting on the last several years wild crafting and growing medicinals, I can safely say things are changing and a greater rate than in the previous 15 years that I have done this work. Firstly, I have noticed as you have too i am sure that the weather is somewhat more erratic and growing moreso every year. There are many more insects in the garden, though this is more prevalent amongst the vegetables than the medicinals it is still noticeable.
In the wild the plants are coming earlier or the length of time of their availability for harvest may have changed duration. For instance, here in the northeast the Fall is much warmer. The killing frost comes later most autumns which means we can have more picking and digging time. The erratic weather means that though there is a longer season in general the weather shorten the window, destroy a crop or just generally mean you must pick while you can and not put it off. the extreme heat or excessive rain and the fact that it tends to come in deluges greatly influence harvest timing. We are so blessed to have so many healing plants here and we have to live in synchronicity with them in these new conditions. In the 20 years I have been following the plants around the seasons I have seen a perceptible and definitive shift that is not just random weather. Nature is always talking to us. Take care of it and we all will live better.
