Somewhere underneath (or mixed in with!) that good Scottish sand are 40 cactus seeds just waiting for the right moment to burst into action.
I couldn’t resist, although I have absolutely no idea what I’ll do with them if any of the seeds manage to germinate. Fortunately as they are very slow growers I have plenty of time to come up with a solution, should one be required. The slow growth won’t put me off looking at them all the time but with a thin covering of sand I have no idea where the actual seeds are.
There’s a lot of conflicting and confusing advice out there on the interweb. For instance this site recommends using specialist cactus soil. The British Cactus and Succulent Society recommend well aerated soil of compost mixed with sand and Lophophora suggests a mix of sand, gravel and sphagnum moss peat. So in the spirit of almost complete confusion I mixed seived seed compost, multi-purpose and random sand. Then I spoiled it all by watering it from above which has probably compacted all that nicely aerated soil mix.
Lots of time to see what happens develops though.
