Del Stubbs asked, regarding window screen with foam collars for borer
protection. how I kept the foam in place. I wrapped the foam tightly
with the screen and stapled it up like this. This protects the tree
from the screen and keeps the foam in place. I got the idea from the
FEDCO Trees catalog, which is available online. The "screen savers" do
detract a little from the beauty of the place, but I'm sure the borers
would as well! Thank you to those who responded to my query, Jason
