Carnivorous Plants/Pinguicula moctezumae


Been growing P. moctezumae for some time now, but it never seems to produce much of a root system.  It isn't suffering too much I don't think, but it isn't thriving either.  I can pick the rosette up right off the surface of the pot.  I tried using grittier potting mix without any peat, but this didn't seem to work much either.  It is grown with good light in a greenhouse, pot not sitting in water, western Oregon.  Should I try a potting mix even more open, say with more perlite/ pumice?

Hi Deven,

Try this.  Mix your soil at two parts sand, one part peat, and one part perlite.  Do this dry, then to that add one tablespoon of dolomite lime to each cup of soil.  Once you've mixed it wet it down thoroughly and re-pot your plant into that mix.  Since we started adding the lime to our butterwort mix we've seen a dramatic improvement in the health of many species.  Be sure to use powdered lime as opposed to the prilled types.  Everything else you're doing sounds good.  If you're not doing a light foliar fertilization, that helps too.

Good Growing!

No terrariums. No myths. No nonsense.
Just the straight facts from guys who grow and propagate
thousands of carnivorous plants each year.

Our focus is to help help growers diagnose a specific plant problem and offer solutions. For example:
  • Why is my sundew not producing dew?
  • Is now a good time to divide my Sarracenia?
  • Why are the traps turning black?
  • What's a good substitute for perlite?
  • Why didn't my seeds germinate?
  • How do you deal with pests?
  • Can you identify this carnivorous plant for me?
We no longer answer general, how-to questions that are already posted on our website or demonstrated in our DVDs. For general plant care, please read our care guides:
