Can anyone tell me is it possible to mix slow-release fertiliser(Osmacote)
To bags of peat potting compost(80L)
I have been given a bag of Osmacote granules(controlled release 3-4 month.)
With No instructions on the amount to use.
I Would like to mix it with the 80litre bags
to pot-up some trailing geraniums and fuchsia plants,
As most of the plants from my local nursery have Osmacote granules
in the compost and look good

PS: Hope this is not a dumb Question
