I have been growing Boophone and Brunsvigia seedlings.. actually some of the same Boophone that Ken is talking about (I got a few of these seedlings from him two years ago) in a mixture of 80% Turface MVP, 10% Local DG, 10% compost...... It has worked very well for me. I am now pushing my luck with some Gethyllis grandiflora in this mix. I spritzed the pots through the summer on my winter growers without problems.. Turface is a calcined clay product sold for Infield amendment.
