The plan is Solarization. I have bacterial and fungal issues in almost every bed. The only solution I know of for that, save replacing the soil, is solarization. Soil solarization is a non-chemical method for controlling soilborne pests using high temperatures produced by capturing radiant energy from the sun.
So I removed the peas, raked the soil, gave it a good soaking and covered it up. I'll let that cook until we put the garden away in the fall and we'll see if it helps next year. I have tweaked my garden rotation to get all the beds solarized for half a season within the next two years.
