Q.Verticillium wilt in my tomato garden
I plan to follow the advice about wetting the soil and covering the garden with plastic to use the sun’s rays to heat up the soil, acting like an autoclave to kill the fungus. Is there anything else I should do in the autumn, now that I’ve removed the dead plants and black plastic mulch?

Clean up any debrese and dispose of.
