Re: CULT: black walnut toxicity & iris


Guess I should have mentioned my folk's iris are under the south and west
sides of the trees.  The tree limbs have been trimed up at least 20' off the
ground and black walnuts just don't have as thick a canopy as a lot of trees.
Plus they are old and the last few years have sustained storm
damage......every little bit helps :-)  
Anyway, they'll be gone before the iris will ;-)

blame the walnut drip for killing some rhododendrons - the only ones
that died were the ones under the drip line of the tree.

My question is, why intentionally try to grow iris in the shade of a
black walnut?  Isn't full sun supposed to be required for good bloom?
