Soil vs. Fertilizer
When using any fertilizer, does that fertilizer manufacture formulate their product assuming the gardener's soil will be ideal (perfect) for their plants of choice? In other words, is it safe to assume that no matter what fertilizer you choose and use it according to their directions, that it won't help much if your actual soil is unbalanced in nutrients and/or the pH is way off. Can any fertilizer help balance poor soil?
BTW, here in SW Ohio, almost half of my 62 tomato plants have suffered some kind of disease. Most have had aphids since day one. I've regularly sprayed with Daconil/Neem and nightly clip off any mostly blighted leaves. I am winning the war, but losing a few battles, about 10 dead plants. Still picking and have aroud 400 on the vines that are left and still growing and flowering.
