Emerald Green Arborvitae
Hi all, I'm a total newbie to the green thumb experience.
I transplanted 34 Emerald Green Arborvitae last fall and everything has been going great up until the last 3 weeks or so. Originally the trees were growing in clay soil and I transplanted them into dirt with more rocks than I would care for.
Some of the trees are doing great and a few not so great.
I have spread fertilizer around the base and I water them with two soaker hoses (1 on each side) and a sprinkler.
The problem as you can see in the picture is that they are browning from the top down. I have looked on line and can't seem to find any info for browning from the top down. In the first picture the two trees on the left were a bright green and the tree on the far right had a brown top. Now it's starting to swing the other way. The far right is coming back and the two on the left are starting to brown.
Could it be the fertilizer is burning it or are they still not getting enough water?
