I have a 250 sqft, raised bed garden in which I have planted numerous herbs, veggies, and 20 tomatoes with great success over the past 20 years. However for the past 2 years the tomatoes have suffered greatly. They grow great for the first 5 weeks, flowering and starting fruit, but then the entire plant wilts and essentially dies. This is just about 75% of the 20 plants. All other veggies and herbs seem to be doing well, although last year I lost the cukes and zucchini to what appeared to be the same problem. I have treated the entire garden 3 times already with Bonide Fung-Onil. I had the soil comprehensively tested this spring and did all necessary additions to bring it up to snuff, but still have the problem. Never had this problem prior to 2023. You should also know that I have a black walnut tree about 20 yds away from the garden, but since the beds are raised, I never really thought this was an issue (and it never was an issue before). My questions are: 1. Do you think this is fusarium wilt? 2. Is there anything I can do this year to save the remaining tomatoes? 3. If it is Fusarium, what can I do, if anything, between now and next year to rid the garden of the problem? Thanks for listening. I appreciate any thoughts you might have.
