Not only on starting but also during the year. In November and again in May. Over doing, yes. I can only imagine what you have to do with so many different soils. Mine are all in the same local with pH values not far from each other UNTIL I get ahold of them. As you told me, I'm also neutralizing the fertilize water. Good Call. Thanks
