i recently moved to a home with a few mature black walnut trees. i know
that tomatoe plants can't survive near them. unfortunately, the literature
i have doesn't say how far away i need to plant in order to get those nice
ripe jersey beefstakes.

does anyone here have a clue?

I've very successfully grown tomatoes about 75 feet from a
grove of black walnut trees. It didn't seem to hurt them.

I've no experience with closer distances.

I think you're pretty safe once you get out from under the dripline of
the tree. The juglone is exuded by the tree's roots.

My wifes aunt has strawberries, flowers, apple trees, asparagus and grape
vines within 25 ft of her black walnut tree. I would say that the drip line
would be your boundary, as Bob said.

Plants of the Nightshade family (Solanaceae) which includes potatoes,
tomatoes, eggplant, sweet peppers and chili peppers appear to be
extremely sensitive to the juglone from black walnut trees.
We have many black walnut trees on our property and, unfortunately,
one very large specimen is located rather close to one corner of our
rear garden. While the edge of the garden is a few feet outside the
drip line of this tree, none of the above plants will survive in that
corner. We learned from bitter experience that they will do quite well
for a month or more after planting but then as their roots go deeper
the plants start to decline and eventually die off completely.
Sweet corn, onions, garlic and parsnips planted in this area appear to
be not affected at all by the walnut.
I have tilled up live roots of this particular tree at a distance
greater than twice the radius of its drip line. Therefore, to be on
the safe side, I would recommend that you plant tomatoes no closer
than a distance equal to at least twice the radius of your tree's drip
line.
Good luck.

I wish black walnut would retard the growth of *something.* I haven't
tried growing tomatoes in the middle of a back yard shaded by giant
black walnut trees, but everything else that can stand some shade does
just fine -- ivy, forsythia, violets, privet, iris, daffodils, mint,
lemon balm, ajuga, magnolia, gardenia, honeysuckle (vine),
blueberries, and weeds I can't identify.

I don't mean that I don't believe in juglone. An almost unreadable
Cornell page says, "Juglone is released by the roots of the plant, but
it is not very soluble in water and doesn't travel far in the soil.
Some examples of plants that may be affected are tomatoes, black
alders, alfalfa, apple trees, corns, beans, potatoes and many others."

I wonder how much the effect of summer shade contributes to this?

thanks for your help folks. i've done more research and it seems i need to
plant at least 20 feet from the dripline of the tree.
