I have an E. cordigera that I have had for 3 + years. It bloomed the first year I had it, skipped a year, and bloomed last year, nice show, but not spectacular.
Currently it is in a terracotta pot, mostly in lava rock (maybe 70 - 80%) with a little charcoal and coarse fir bark.
The original plant had one large pseuobulb, green, glossy and the size of a medium onion (roughly 1.5 to 2 inch diameter), and some smaller older pseudobulbs.
The plant has added only two pseudobulbs since I purchased it, about one every other year. Significantly smaller (1 inch) than the large one I mentioned. No new growth this year.
Added later, photos:
Neither of the newer pseudobulbs has ever had a new root develop. Not a single root, not even a nub, no indication that a root was created but later eaten by pests. The youngest of the 2 newer pseuobulbs bloomed last year. The plant is clearly still absorbing water, leaves seem fine, pseudobulbs still shiny, including the old pseudobulb. The 2 new growths both came from the older pseudobulb.
My understanding is that E. cordigera can be picky about potting. Should the current potting media/pot be suitable for it? Should I consider mounting or placing in a wood basket in the future, no medium? Over the winter, I have considered shaking any loose medium out of the pot and seeing if the plant makes any new roots.
I would appreciate advice from anyone that has successfully gotten this species to grow and produce new roots and growths. What should my next move be?
Thanks.
