I fell in love with cacti after visiting the Desert Botanical Garden in Phoenix, AZ. I bought my first big cactus last summer. When I went to bring it in before the frost, I noticed it was flowering! I also noticed it had several places where it appeared damaged. I'm in Zone 6b. It's in my garage under timed lights. I'm attaching pictures of the damage. Any advice on how to repair it would be great. Thank you so much!
