Anne, I love the Bletilla buds!
I checked mine yesterday - they are growing smack against the South facing house wall for many many years now, but with this unusually cold Winter I was wondering if they survived. I was very happy to see ca 1 cm tips coming up, most advanced were the ones at the wall. I removed the pile of Oak leaves ( I always mulch them after they drop their leaves) , pulled some weedy grass between them and covered them again with those leaves, much more loosely this time.
Hopefully it will warm up one of these days around here. We had a 55 degr. F day yesterday, but it is supposed to go down again to 17 degr F tonight with perhaps snow on Tuesday. That's why I covered them again.
Ah yes, the dreaded Sphagnum moss! I simply do not buy plants anymore at Shows if they are in Sphagnum, ( or show me the roots) since I will have to repot them and many times the roots don't look so hot underneath that Sphagnum.
