How do I deal with verticillium wilt

Asked June 4, 2014, 4:56 PM EDT

I just transplanted black caps into a raised bed with new soil and about 8 of the 12 plants are showing signs of vericillium wilt. Do I have to dig them all out and put a disease resistant crop such as asparagus or brocolli in? How long will that fungus remain in the soil?

First thing I need to know is how you determined it was Verticillium wilt? Assuming it is, then yes, you have a big problem. It is very long lived in the soil and susceptible crops will have a hard time dealing with this problem. I would work with the plants you have and see how they do. Vert wilt can be a chronic problem year after year with some years better than others. In other words, you may still achieve your goal of getting fruit, just not as much as you planned.
