I have an unusual species of birch in my front yard, a Red River
Heritage Birch. The bark is sort of a light orange, and looks like
it's always peeling.

Anyway, I notice that I seem to have a lot of yellow leaves falling of
for this time of year. The tree is by no means going bare, but there
are always leaves dropping.

I recently sprayed as much of it as I could with Isotox, thinking I
may have Birch Tree Miners, but could only reach the bottom two-
thirds, (the tree is forty feet high).

I've noticed lots of other birch trees, mostly regular white clump
birches, also with lots of yellow leaves on the ground, so I'm not too
panicked.

I was just wondering if anyone has any insight into this. Is this a
common thing with birches?? I've had this tree since it was a
sapling, but this "leave thing" seems to have started over the past
few summers.
Any helpful input is appreciated.

As others have said, it needs water. Water it!! I lost two just like
that last summer because I found out too later.

Actually, here in Greater Boston, we've had a WET Summer.
Way above average rain fall.

The only I'm sure is NOT causing this is lack of water.

With a birch, that (hot weather and water stress) has to be the first
thought, as to the reason. That being ruled out, my next guess would be
Iron Chlorosis, which could be caused by your soil being too alkaline. But,
don't guess. Be sure. Take a leafy branch to a good local nursery and have
it checked out. If you rule out Chlorosis, then my only other guess would
be fungal leaf blight, which is also treatable (but can be a pain). Your
co-op should be able to diagnose this from a soil sample.
