black fly has overtaken cherry trees what can i do?
For the past 3 years i have been growing stella cherry trees without success. They blossom but then are ridden by black fly. i have tried sraying them with bug off, but that does not work. one of the cherry trees leaves change colour from green with orange spots and curls up what is the problem, and what can i do so solve it?
