Soil Mix for Mexican Pings

  • #21
I use normal multi-purpose compost (potting mix) with added John Innes (potting soil) for Mexican Pings. The few that I grow seem to like the nutrients. I've tried non-organic mixes, but in my conditions growth is slow using these. I've also added calcium in the past, such as calci-sand, and I can't say that I notice any difference in growth rate but it makes a nice top dressing. Maybe the mixes I use have enough trace elements to mean that calcium is not required.

' in situ' the moranensis have a alcalin substrat .

for all my mexican and some of my temperate I use this form of mineral substrat

cat liter 50% [ now I add with this cat liter 30% akadama ( bonzaï clay )]
river sand 12.5%
vermiculite 12.5%
calcareous sand 12.5%
pouzzolane 12.5% ( volcanic rock)


for the gypsum specie I use just gypsum 50% and river sand 50%.

for me it is not enough calcareous like a coral .

I prefered the cat liter , this substrat is very ideal particularly for its alcalin ownership and its water retention
add with the other element it is top.
