Hello These trees are all transplants. I am concerned about the bark at the base of trunks of some of them. As the pic shows the bark is splitting and there are sow bugs present. There are also very small bore holes in the wood under the bark.These trees mean a lot to me. There is about 60. I dug them out loaded them in my truck and did all the transplant work and the babied them through the last few very hot and dry summers.Any help or advice is welcome.I live on Southern Vancouver Island. Thanks Jack "Who the cap fit, let them wear it"
Thuja occidentalis 'Fastigiata'. Looks like the site is on the damp site, probably why some trunks have split. Also: might any of them be planted too deep? Sow bugs are just taking advantage of shelter provided by lifted bark. Holes bored in the wood would not be good. To get rid of those you would have to find out what is doing the boring and use a control method known to work on that particular insect, in a manner known to be effective. But they are probably there because the site conditions have already distressed/damaged the trees beforehand, same as the sowbugs.
