Btw for most pings, the soil to use would be peat and sphagnum, or just sphagnum or peat depending on the species?
For temperate and warm temperate pings, a peat sand mixture or sphagnum would be good. For Mexican pings most people use no more than 25% peat if any. I use a combination of Arcillite/Zeolite clay
Gravel (sold as “Aquatic Plant Media” - evidently people refuse to understand that “media” is a plural of “medium” but I digress), mixed with silica sand, fine pumice, sometimes just a bit of peat, and a very small bit of chelated iron, which supposedly increases color in some species. (I am not convinced.) I also tried adding limestone (aragonite) sand, and have planted in pure aragonite. Basically things do well as long as they stay moist and they have good air circulation. However one friend said that his P. gigantea took off after he started adding limestone gravel to his mix. Was it because of the lima, or greater aeration due to the coarseness of the mix? I don’t know. Others have said that adding lime has a little effect. Still, many of the Mexican species we grow, are naturally found on limestone cliffs, so it stands to reason that at least some of them might benefit. Unfortunately I don’t have the vast amount of space to do the appropriate comparisons!
