Off the shelf mix
There is a mix for sale commercially here which I thought may be suitable as a free draining citrus mix.
Dalton's Cutting Mix
A well proven and recommended, commercially used blend of clean Daltons 3mm Pumice, Daltons Propagating Sand, with a percentage of organic material added to assist in water retention, without compromising air filled porosity. Daltons Cutting Mix promotes early root development and feeder root establishment, minimising the time between cutting and potting up. Available in 20L bags.
Any thoughts on the above ready made mix for citrus in pots? We don't have turface here so I've been looking for alternatives and this came up in my travels.
Thanks in advance.
