The tree trunk scratch test!
Today I took a walk around my snow covered yard in the -25 degree weather looking at out trees, shrubs and vines. I have a weeping caragana that didn't quite make it's way into the ground last fall. I had every intention of burying it in the garden before winter set in but one thing led to another and it never happened. With a guilty heart I accepted the fact that the tree would be toast in the spring. But to my surprise after performing the trusty old "scratch" test the trunk is green! So with new found excitement and hope for this little tree, I piled more snow around it and moved on to "scratch" every exposed branch and trunk that I could find in my yard. My question is - If the tree is green now at the end of January with -25 degree temps will it make it all the way through to spring? Is there anything I can or should do at this point to help it along?
