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.



Lots of trees in my area (metro Washington DC) had been dropping some leaves
over the last month. I was told that trees normally do this when stressed
from not enough water. We had a terribly dry spring, and seemed to jump
right into August type weather. Many plants were suffering. Hopefully last
weeks drenching rains will turn things around.

My very old Black Walnut trees were already dropping their nuts in the third
week of June. The nuts were only up to about 1" diameter, far from mature.
Normally they drop when about 2" to 2 1/2" diameter, in August, IIRC.

If you have also been having excessively dry weather, I'd say what you are
seeing is normal. Just the tree's way of protecting itself.
