I started on the compost operation afternoon and notice steam coming from it and checked the temp and it was 140 degrees in 24 hours!!! I got most of it back in the bin and added a little more of the horse bedding and it should be 160 to 170 degrees in a couple of days. It was quite a achievement for me as I have lacked my stamina for the last 8 months. It felt like chronic fatigue that people describe. We had a damp morning 4 days ago and the Red Gold Potatoes are blighting however they are about ready to harvest but I see the blight in the Yukon Gold now and they need 2 or 3 weeks more...
A word of warning .. go lightly with horsemanure and make sure it composts thoroughly and at as high heat as possible. Disgetstive systems of horses are not to efficient ... they pass ALL weed seeds intact. If your compost pile does not heat thoroughly .. at least 160 .... you are going to be sowing weed seeds as well. And .. those weed seeds germinate quickly and grow rapidly in that rich compost host.
Been there .. done that as the saying goes. Tool me 5 years to get weeds somewhat under control in my perennial beds.
A better idea. Still use you horse manure .. but isolate it in its own compost bin using garden weeds you might be pulling or cutting. Kill two birds with one stone. None of my weeds ever go into my main compost .. I compost them separately. Weeds are always a problem, but I have cut production of them down by 75% since I started this.
