I have a bunch of autumn olives on the property. Most are doing fine even with pocket gopher harassment. I was looking at one of them today and it looks like it is either drought stressed or in need of nitrogen. I thought how could this be? I just watered them recently and they fix their own nitrogen. Any insights?
I swiped it off another thread here on Permies :)
I have used epsom salts for Mg deficiency before, not sure if that's best, more research would be appropriate...
I see a lot of threads here on minerals, too sick to dig through them today, might be worth reading a bunch of them.
Also WELL worth reading Bryant Redhawk's soil series:: Soil articles I think I recall him discussing Mg in there somewhere. Probably several somewheres.
