In massachusetts where I used to spend most of my summers... early August was that time of year... didnt have that problem last year and will be in Canada this year so I dont know.
the biggest drought is during the summer when most outdoor plants are still growing. but we still got the indoor to back us up
drought comes(where i live) middle of june of beginning on june til julyish. basically begging of summer.. but its been every year for the bpast 3 years so basically theres about to be a drought for me
