After further review it seems I am using Pelletized Lime and not the Granulated Lime that Belleclare Nursery recommends. Home Depot has deceived me. This is what I've been using: http://www.homedepot.com/p/Soil-Doctor-40-lb-Granular-Limestone-54055026/100343171?keyword=granular+limestone
It says "Granulated," but it's not the real deal.
I may try again next year, but for now I'll just be adding that stuff to my mix.
