Today I bought two seedlings, specifically a Gongora galeottiana and an Aerides multiflora. Both were classified as "medium seedlings".
I'd like to eventually switch them from the sphagnum moss they are in, to hanging baskets with a bark/sphagnum mix. I've never had seedlings before, and I am wondering if there is some sort of general rule for when you can take seedlings out of their comfy sphagnum beds and repot them?
