r/Trichocereus

the warm growing season is quickly coming to a close in the northern hemisphere. i just want to look back on some of the notable things from the past season before it is gone

this is is ruthless and extremely hard to get rid of. Every couple days i use tweezers because spines are rough on my knuckles And pull it all out. I hope before i seal it up for winter storage it is not issue.

So this was my first cactus it was a PC and it’s been a year and a half doesn’t seem to have grown at all all my other cactuses have grown in leaps and bounds. It seems healthy, but this was my first one and I reused the pot and didn’t make the medium myself like I did for my other Trichocerus cactuses. Any help suggested

Thought some might enjoy/learn(maybe)?

TIA

Jan 25, 2025 was when I got my PC's from him. Im sure I've talked to him before that, but I would need to go through my comments lol.

San Pedro monstrous tower as the base.
Trichocereus monstrous crest on it.

Friend brought this over, gonna do some slab & puck grafts maybe, idk

Are there any advantages to cutting the apex off in order to pot your cutting log style? I gather that sparing the primary growth point kicks off reestablishment much faster but I am more interested in base stability and encouraging more pups. If cutting the apex to plant as a log will significantly harm the cutting then I will just pot vertically and try log style another time when the opportunity presents itself, I would appreciate any advice as I am inexperienced and don’t really know what I should absolutely avoid when trying to grow cacti. The pictures are the cutting I received from my grandma, and the parent cactus that she has been growing since before I was born 18 years ago. Fun fact, the pictures show entirely new crown growth over the course of about 9 years. The original, 17ft tall, crown fell over in a rainstorm; everything depicted is reportedly grown from the original root system : )

For 100 years Norrköping in Sweden have had a cactus exhibition every summer. The cactuses are stored during the winter and the next year they are planted in a new unique formation. No year is the same.

I was there 2 weeks ago. It was a lot of cactuses, semperivivums, delospermas and some​ euphorbias too. Many of their very old columnars from earlier years have unfortunately died but the plantation is very impressive anyway.
