Problems with Thuja occidentalis smaragd
Hello. I was told these conifers should not turn brown in autumn/winter but it seems mine do... I was also told they are quite hardy.
I planted these in the spring. They grow in heavy clay and it rains a lot in Scotland. Can that be a reason? Or is it a some kind of mite or lack of minerals? I was told not to use anything in the first year.
Any help will be much appreciated!
