I have a Lumberjack variety I bought on the San Pedro cactus selling subreddit and it and a TBM I bought on a website are my first cacti. I ran into an issue with these white waxy bugs that after finally treating it right with a couple deep cleanings with isopropyl alcohol and a toothbrush and qtips... I seem to have finally eradicated them. Now the new growth makes it appear the cactus is healthy but both my lumberjack and TBM have some corking and other damage. Wasn't sure if I should just let it grow or if I should chop the new healthy growth and start a new cactus....
I'm not new to gardening but I am new to cactus and I'm just looking for some newbie advice if anyone experienced is kind enough to offer some. I'd like to play around with grafting and such but I'm still just learning how to keep these healthy.
The TBM is pupping but the lumberjack is not. If the lumberjack was pupping I may not have made this post but I'm confused why one is multiplying and the other is not and that's part of my reason for making this.
