Subject: Vegetable Garden Wilting
Category: General Interest
Posted On: June 08, 2004
From: meemawpaw
Message: Our vegetable garden wilts every year. It comes up beautiful at first then spotty wilting starts and then nearly the whole thing dies. We cut down a walnut tree a couple of years ago and there is another one in a yard about 50 yards away. There are two other gardens close to it that doesn't have a wilting problem. We don't over-water. This year it is really bad. I have consulted Dick Crum but even he is stumped. Can anyone help? There are no evidence of cutworms.

Message: MY FIRST GUESS WOULD STILL BE THE WALNUT. EVEN AFTER A TREE IS CUT DOWN, THE JUGLONE PRODUCED BY THE TREE IS STILL EVIDENT IN THE ROOT SYSTEM FOR SEVERAL YEARS. WHEN PLANTING AROUND WALNUTS, BE AWARE THAT THEIR ROOTS EXTEND WELL BEYOND THE DRIP LINE OF THE TREE. jUGLONE LEVELS SEEM TO INCREASE WHEN TREE IS UNDER STRESS. ALSO BE AWARE THAT DAMAGE TO PLANTS IS GREATER IN POORLY DRAINED SOILS. THE EFFECTS THAT JUGLONE HAS ON PLANTS IS ALSO VERY SIMILAR TO VERTICILLUM & FUSARIUM WILT. ALL THREE WILL CAUSE WILTING MID SUMMER. VERTICILLUM & FUSARIUM WILL TEND TO CAUSE PLANT TO YELLOW ON ONE BRANCH OR ONE SIDE OF PLANT PRIOR TO WILT. TO FIND OUT FOR SURE, I SUGGEST CONTACTING YOUR LOCAL GOVERNMENT AGRICULTURE DEPARTMENT FOR INFORMATION ON A NEARBY LAB TO WHICH YOU CAN SEND A PLANT SAMPLE.
