I just realized I did something not too smart. Last year my bell pepper bed did not do well. The plants wilted and produced very few, pathetic peppers. I figured it was a bacterial wilt. Fast forward to this spring. I rotated my crops and planted the peppers in the bed that had previously grown root crops and some lettuce.
Then for the fatal mistake- I planted the previous pepper bed with potatoes! I'm not sure what I was thinking. I am aware that potatoes, peppers, eggplant, and tomatoes are all Solanaceae. Now my potatoes are wilting and dying.
I need a giant sign on this bed to remind me no Solanaceae! After reading about the different wilts, I think I have fusarium or verticillium wilt. Both of these are caused by a fungus and unfortunately there doesn't seem to be anything I can do to save the potatoes at this point.
They recommend no Solanaceae in the infected area for 4 - 6 years! I sure hope I can remember. Also, planting mustard as a cover crop is suppose to help. Mustard has anti-fungal properties and can help kill the fungal culprits.
Hopefully I'll get a few potatoes this year. I've never tried a fall crop, but this may be the year to try.
