I Put Fresh Horse Manure Around The Base Of My Fruit And Nut Trees And Covered With Cardboard Andmulch

Question

Clear of their trunks. Should I remove until manure is composted properly

Answer 1

Horse manure is rather safe to use, uncomposted. I think it'll be OK. Many sources say that it is too "hot" for use uncomposted, but I find this to be true with COW manure rather than HORSE manure. Personally, I'll use it fresh or composted.

There is one thing to note, though. Weeds can be an issue. However, with the mulch and cardboard on top, I think it'll be ok.

However, if you want to compost it in the future, then it'll offer faster availability of nutrients to the plants on application.
