Thanks for the connection. A lot of visitors to garden comment on
garden next to Black Walnut trees, now I can send them to info, rather
then explaining all the time.
When the huge branch came down on the iris garden, it was
chock-a-block full of near ripe walnuts, part of why it was so heavy.
Knocked off a number of iris seed pods, but they were near ripe, so not
a major problem. Branch (actually more like near one third of the
tree) was over a foot thick at base and about 30-40 feet long. After
it was cut up and removed, there was a ton of leaves and fruit left in
garden. The last of the wood was burned in fireplace early this
winter. Absolutely no bad effects on iris growth. Plants next to the
base of tree were the tallest, strongest, and had the best increase in
the garden this year. (perhaps a bit more sunshine this year) But,
they were selected seedlings and one will be introduced this year.
So no effects on bearded iris. Good to know Siberian can be effected.
None will go into those locations.
The squirrels go nuts over the nuts. They are so excited when they get
the first ripe fruit of the year. They plant them all over the garden
so I'm constantly pulling up small black walnut tress. There are always
piles of empty shells left in and outside various outbuildings. The
nuts are delicious, but getting them out of the shell is a real task,
best
left got the squirrels.

Actually, the genus is Juglans, the causal agent is juglone.
