I have no Neem oil, but I do have alfalfa pellets mixed with manure which are quite ammoniac and generate actinomycetes freely. I spread some of those on the soil.
Since this is a cottage garden type situation and not a commercial growing operation, I am going to take a low key and slow approach of working away at balancing the soil -- because I feel that is the best solution anyway, and really the only one available to me.
I'll get some Neem oil too, first chance I get.
As for the shade cloth, we are having an overcast day and it's forecast to be rainy and cloudy all week, so I think hot sun won't be an issue. If the weather shifts I'll probably do that though. Thanks!
