This Sonerila has started coming in via some plant sellers out of Asia recently. I’ve only had it a few months, so can’t say much about it, other than the necessity of monitoring it closely for the first few weeks. The plant below came in with few roots (maybe none? can’t recall), and wilted multiple times the first week. It’s in a completely sealed bin with moist sphagnum and 100% humidity. Despite this, the stem would go completely limp, with leaves hanging down over the sphagnum. I think it wilted over a span of hours. With generous watering at the base, each time it perked up by the end of the day. Temperatures were low-mid 70’s, and my guess is that for the initial acclimation period, it would be of benefit to the plant (especially if they are unrooted) to keep temperatures on the cooler side.
Of the cuttings I took, the ones placed in clay substrate so far have done best.
