Needs to be well rotted, probably about 6 months, put on fresh and is much to strong and could do a lot of damage.
When its ready its great for roses, just top dress usually autumn wintertime
I,d say shrubs and roses, plants that like a rich feed.......

At this time of the year it will need composting before spreading round plants. I would mix it in well with whatever is already in the compost bin and leave it to use in the late autumn or winter months. Horse manure conditions the soil beautifully .... should get some for my clay soil.

Oooooh that takes me back. My Grandad always used to go out and collect the droppings from the Milkman's horse for his Rhubarb. No composting, nothing, straight on the soil round the plant.

Old joke coming up.
Horse muck on Rhubarb? Prefer custard myself!

Ob......oldies but goodies. :0)))

Thanks, all. Autumn for the roses it is, then.

My Mum used to send me out to collect this off the road and against all the rules she put it straight on the roses. Never seemed to hurt them, perhaps she was just lucky.
I wouldn't do it now.

Likewise, Steragram. May be roses were stronger in years past. Just like summers were longer!
