Thanks for the help. You get varying degrees of age in the horse manure. Some nicely composted some the sawdust is fresh with pee. It never seemed to give me any trouble but figured there may be no need to push it this season.
This may look a little low but it is actually much higher than it used to be and I have given up keeping it away from the steel fence which the bottom of is now a couple of inches below the soil. I plan on building up a few rows for the first time this year. Past years have mostly been hindered by being too crowded ( I just can't throw a tree in the bin

) but those that got above the others went well.
If the horse poo is not much of an issue I might get a small load of the more composted stuff and dig that through. I also have a bag of Gypsum so it probably is a good idea to throw some of that on. I think I will still add some blood and bone as well.
I thought I might get all professional like and use weed mat over the mounds with holes for the trees. Then I might cover this with a bit of straw just to keep the Misses happy
Thanks again for all the suggestions.
It's too bad your in such a hurry cause the stories I could tell you, Bushels and baskets of stories, hole crates full of stories. But if you can spare a moment I will tell you one story.
