3 years ago I had a chamaecyparis pisifera boulevard. By the end of winter it was all brown. I pulled it out of it's pot and chucked it in the wheelie bin. 3 days later I put some more rubbish in the bin, I saw the tree was greening up

I salvaged it. Did the same thing 2 years ago, ie it went brown, I chucked it. It went green again but I thought it was a real goner this time... didn't save it...
I have since found out that these trees commonly go brown and look dead but they're not
