I think I should have done this sooner. The sphagnum was looking a bit grotty. So I have 45 little pots with one plant each and one left-over compot with perhaps a half dozen more, depending on how many of those make it. Now I need to number them so I've got some ID on the indivdiual plants.
The ones I potted up in January are on the left and the new batch on the right. I'm glad I was able to squash them all into two trays so I can keep them together.
