Is it possible to treat the soil to prevent late blight next year - or is it not a problem that gets carried over?
Well, for one, most fungi thrive in an acidic environment - the soil in the PNW is quite acid due to the pine trees. So I need to lime it good, better yet, I have about 50 lbs of wood ash from burning up tons (literally) of limbs last spring, I’ll use some of that.
And I have a couple pounds of potassium bicarbonate which is an excellent fungicide, I just didn’t catch it in time.
But no matter what, it would be complete foolishness for me to plant tomatoes next spring in the same place, so I’ll have to move them elsewhere!
