stable manure or droppings from horses in a field ?
Only some stuff bekkie.
I get droppings from the horses in the field over the road and spread it any old time
Stable manure has urine soaked straw in it, it's the ammonia in urine that the plants don't like. Shrubs can cope with droppings though I wouldn't spread anything right up against the plant, they might rot it they're wet a long time and it's a wet year.
I'd collect it and store it a while. You don't need to get every last bit
Gardening is full of mistakes
The mistakes bit is the bit I'm good at
