Hi all. i was looking on the ICPS website growing guides and came across this "...They are growing in pure peat with a 1 cm mulch of sand. The sand helps cut down on cyanobacteria and fungus gnats. "
Has anyone tried the sand as mulch method for their dews or other plants? It makes "sense on paper" to me. I'd like to hear opinons of others on this. The first problem that comes to mind for me though is how would plantlets, offshoots etc fair? I may try this with some orchids though and see if it helps.
