Advice on Satsuki Azalea Bonsai in 5b

[kale]

Hi there! Im in Firestone and have 3 that survived the winter in my window well with a piece of clear plasic draped over it. Never got below 30 in it all winter! Wish I had a better pic handy. Theyre doing well and been waking up over the past couple of months. Fully outside now that we’ll be above freezing for the foreseeable future.

Looks like you have 3 Hardy Satsuki! Do you know which cultivars of Satsuki these are?
Cheers

I have no idea, they were purchased over time of 5 years or so at a local Nursery on Sale....
My real Bonsai life is centered around Japanese Maple and Landscape Penjing using Shimpaku Juniper....

I also do Terrarium Bonsai Landscapes, here are a few examples...the smaller Terrariums are 6" Diameter, the larger with the houses. Is a 10" Terrarium, all are using Juniper Shimpaku, Ying Rock, Common Moss, Mixed ground cover soil....and Japanese Red Crowned Cranes.
