Fresh horsemanure with a covering of sphagnum moss. Water was given freely every day, but the medium and the pot allowed free drainage.
Nothing else was added, the horsemanure providing all the requirements
photo was taken when the plant had 7 flower spikes.
Below photo shown result of added horsemanure. The plant is almost twice the size and has 22 flower spikes
