I have been piling up wood Shavings for years now. I dug into a 5 yo pile not too long ago, never been turned, and they hadn't yet broken down. I know that we shouldn't till, but compaction happens even with soiled bedding piled up outside, and it's too much work to try to dig it out, so I DO till mine to move it.
I still cringe when somebody uses hay or straw that could be fodder, for basic fertilizer. Plus, some of my hay is FULL of seeds evidenced by the little grasses that pop up, and nobody likes pulling unexpected "weeds" from their beds.
Yesterday I worked in DD's yard. I pruned their Rose of Sharon, huge with some dead branches and needed pruning 3 years ago. I found tree of paradise and maple volunteer saplings. I dug down 3-4 inches, cut with my reciprocating saw, covered with cardboard and put a rock on top of each. (The previous owner brought in a LOT of good sized rocks.
Their Drop Dead Red looked a little bit dead. I dug it out to nurse at my house. We'll see...
Meanwhile I planted a miniature rose, "Baby Elizabeth", and another red mini rose, a pack of pink and white wax begonias and a pack of snapdragons. The lavendar rose is green at the base, but hasn't grown any leaves yet. ALL of my roses at my house have good growth, so what gives?
I did the basic weeding, pulling and digging, while the bee guys did their thing.
Apparantly they sent DD's photos. I was too busy to think to bring my camera. More on that when I get a copy.
