The Chamaedorea microspadix seedlings have continued to grow at a steady pace during March with no changes to watering, feeding, etc., but they are long overdue re-potting into separate pots. I have some new pots arriving in April, so I will hopefully be able to sort that out then, although there are other plants for which re-potting is more of a priority. Hopefully they will separate without too much root damage and not take too long to recover.
