Ok, here's the deal, i'm also expanding my upper garden area this year where my boxed in raised beds are. We had the huge ice storm 2 months ago, many trees down etc. Anyway, i had a hickory tree uproot right on the edge of my new garden area inside and accross my fence...bummer I also had a real old oak stump in the inside edge of the fence in the same area. That area approx 10x12 FT. gets a ton of afternoon shade. I just had my two hardwood stumps ground out today. the one area is mostly stump ground type sawdust, but the other is porbably half dirt, half fresh sawdust mulch mixed. I planned on moving my two blueberry bushes and my three blackberry bushes to that area soon. Both were new transplants in the garden last year. Can i plant them in the fresh sawdust dirt mix? Can i use that area to plant any vegetables at all?, or should i just make it my compost area for a few years?
