Re: Mixing up a new batch of potting 'soil'


Dale, if it's thoroughly black and rotted and actively growing you a
nice crop of weeds, go ahead and use it.  I'd add some granite grit,
myself, to ensure good drainage, as all organic material tends to
compact down in pots.  I'd also add some bagged cow manure.

You will have to fertilize your pots.  Someone recommended Ozmacote
and I find it works pretty well to supplement my home made potting
soil which consists of screened compost and rotted woodchip humus,
basically...with added grit and manure....sometimes leaf mould, if
I've got it.  The other good thing about Ozmacote - for those of us
whose minds are failing - is that you add it once and it lasts for
however many months the particular formulation is designed for.

My potted plants all seem to love this and the spent soil makes great
additions to borders or fill for raised beds.  I do notice that it
tends to be quite neutral in composition (as most thoroughly
composted organic matter seems to be), so those plants who prefer
more acid soils need a bit of peat or pine bark fines or something
acidic to do well.
