That's a really healthy looking cacti. I have a bunch, and while mostly easy to care for, some really struggle here in my northern climate over the winter even though they are indoors.
Thanks for sharing this. Gives me a little inspiration to share a few of my own!
Cheers!
Glad that my cactus was able to inspire you!
We also have a rather cold winter, but in a warm room, nevertheless they are comfortable)
Thank you for your feedback!
