I put in microorganisms in soil this year. If I solarize, will it kill them? For many years, I've had a terrible problem with tomato blight. Will solarizing help that? Thanks for your help. Pam

I do not know the heat threshold of the microorganisms. They are heat lovers so my best guess is they would be safe during solarizing a garden bed.
I have listed a few links for you with more information.
