English walnuts don’t produce juglone. I
suspect the grain crops were unaffected, but I’ve seen other crops affected.
That includes blueberries I planted as a landscape planting at my house. I’ve
grown blueberries successfully before, and these started out okay. But they
were within 25’ of a black walnut. They just never thrived like they should. I
thought because they were both natives the blueberries would be tolerant. So
much for thinking! And I’m aware of folks who had the same problem with
tomatoes. If at all possible, avoid them. Bill William H. Shoemaker Sr. Research Specialist, Food Crops 630-584-7254, FAX-584-4610 From:

[mailto:market-farming-bounces AT lists.ibiblio.org] On Behalf Of sunnfarm AT netscape.com I have a single English walnut which I guess is not much
different than a Black next to a field that I don;t plant anymore but when I
did I grew tomatoes broccoli cauliflower and sweetcorn through the years with
no ill effect. My neighbor has many Black walnut trees along the tractor path
planted on both sides with field corn wheat and soybeans and the crops grow
well enough. I think a lot of the problems people see especially near the
drip line is the tree taking up all the available water and throwing shade over
the plants that is harming vegetable growth... Bob. From: wshoemak AT illinois.edu Black Walnuts produce a phytotoxin, juglone, which will
inhibit the growth of many species of plants. Most vegetables can be affected.
The high-risk zone is anything within 1.5x the drip line. Some think its more
because it depends on sensitivity/tolerance and movement of walnut debris. Bill William H. Shoemaker Sr. Research Specialist, Food Crops 630-584-7254, FAX-584-4610 From:

[mailto:market-farming-bounces AT lists.ibiblio.org] On Behalf Of E C GRANATA Folks:
I remember that black walnut trees are not friendly to gardens, but can't
remember particulars. Can anyone help? How far from the tree --
from the trunk? from the drip line? Netscape. Just the Net You Need. |
