Molten sun rises behind the Paper Birches in the National Grove of State Trees
Everyone loves this planting of Betula papyrifera (the state tree of New Hampshire).I don't know how we keep the trees so healthy. We're a bit, actually a lot, south of their favored territory. It's way too hot and humid for way too long in the summers both for the birches and for me. Back in the days Lindane it was no problem to keep borers at bay. I'm glad that we're getting those dangerous pesticides off the market but....Now, though I think Imidicloprid is labelled for borers, I don't see how it can work this well.
