Q.Cypress trees have turned brown
I live in Mallorca Spain and have 40 trees I have had now for 7 years and are all nearly 6ft tall, this year has been very hot and the wind hot also, most of the trees have turned brown and 3 of them are starting the turn black, is there anything I can do to reverse the situation. Thanks in advance.

Yes. In This case, I have cured evergreens of many types using a simple wettable sulfur powder. This is indicative of a fungal infection. The sulfur will acidify the soil, Which the trees prefer. It will also kill off any infection in the soil.
