How do I get rid of red spider mites that are killing my conifers?
Yes, red spider mites do not like damp conditions, but you have to spray the inside parts of the trees and do it regularly. Some rain would have been good! This happened to a tree of mine and it’s OK now. However, I must point out that the parts of the conifers that have gone brown rarely green up again so it’s probably a good idea to cut out the dead bits.
