Hi! I'm new to your blog and I wanted to try propagating. I've already started with some succulents, but I was wondering if you have any specific methods for propagating cacti? I assume the process is similar, but it'd still rather not mess it up! Thank you for any response!
Yo! This is a super g question! Sorry for taking a while to respond, I was trying to think of the best way to demonstrate what the heck I am talking about. I’ve settled for a gif and hopefully it works lol
So I don’t keep many cacti, they are fiddly little pricks and we get way too much water to keep them in an exposed area outside.
Cacti cannot be propagated like succulents. While succulents you can leaf-propagate, cacti (obvs) cannot be leaf-propagated bc they don’t have leaves.
Sooooo you have to wait for them to ‘pup’.
Some cacti do this by forming new pups next to the plant:
These are super easy to propagate, you can use tongs (so that u don’t prick ur fingers) to twist each pup off the mother plant and they should just pop off.
But some other cacti propagate super weirdly, and form pups around the crown of the plant (like they just form all over the cactus)
These are a little trickier to propagate, I cut into the mother plant and remove the baby like a weird little tumour:
And then you are left w/ a new cactus baby yay!
Now honest 2 god chuck that sucker on top of some DRY sandy (river sand, not beach-sand) soil and he will form roots in about 3-4 months. Try not to water at all for the first month bc otherwise he will rot.
G luck w ur new baby.
PS: dw if your cactus hasn’t formed pups yet. They are super slow growing and sometimes take years to form new pups. You can try ‘coring’ to speed up propagation which involves cutting holes in ur cactus, but I haven’t been game to try it out. Try googling and give it a go if u want? I personally prefer to wait for them to form naturally :)
PPS: The white stuff is cactus milk. It is basically like us bleeding to form scabs which protect the skin, so don’t wipe it off! It will help to seal the cactus. You can also put cinnamon in the wound of the mother plant to protect it from rotting!
