Thanks Tamideel: I forgot about this thread.
I have stored the tufas for the winter in a corner of my deck.I started the thread because I was sure I paid a huge sum for the first three tufas. I doubt I will do that again.
The season went on with good development for the alpines and semps.
July
AUGUST
Here the tufas are for the winter.
This corner will fill with leaves and snow.
