Helping with cutting and transplanting
A few years ago, I posted the following about one of my cacti not looking so hot. (this is the post)
Someone recommended I "cut the bottom part and keep the top part. Put crushed charcoal or cinnamon on the cut part to avoid fungal attacks, and wait several months for roots to appear before putting it in the ground."
I am trying to get more information on this. Is crushed charcoal something I should buy or is it literally crushed charcoal? While I am waiting several months for the roots, how should I be storing the cacti? On top of substrate? On a paper towel?
Just trying to get some clarity on this process. Thanks!
