I don't know anything about cacti.  Just was wondering about this one.

Cereus hexagonus or Cereus hildmannianus...I think the second.

Greetings to all. So i have a question for anyone of you that is familiar with L.W. Caespitosa. How often do you water yours?

Any one got an idea on what type of trichocereus this is? I found it at a local flowershop here in Norway maybe 4 years ago. It was much smaller then, just had to have it :D I hope it's not a t. cuzcoensis. I'm having a hard time identifying what it might be.

Identifying an Echinopsis/Trchiocereus from flowershops can be very frustrating if the cacti are not labled properly.

Your cacti could be anything..

 

It could be a Trichocereus Peruviana variation, but that's the only active one that looks somewhat familiar.

A Bridgesii at that size would have def. made longer spines.

San Pedros with that long spines are absolutely rare and you'll def. not find them in a flowershop, except it's in the andes somewhere at 2000m above sea level haha.

 

Ther are also many inactive Echinopsis that come to my mind, like Echinopsis macrogona.
Usually they have more spines, but I see that your cacti didn't receive all the light it needed. So that would explain why it has less spines.

I personally think it's a young Trichocereus Cuzcoensis.

The chances you got a rare peruviana or pachanoi variation is very slim. Macrogona has more spines..Bridgesii longer ones..

I'm not 100%, but almost.

 

Peace

How long has it been since you've got your cacti? How was it cultivated before you got it?

Care to answer in this (click) thread instead of here? Since you don't need a ID of your cacti :)

Peace

If I had to guess.....I would say a cross of a bridge and a peruvianus, leaning more towards the peruvianus genetics....or it could be, as stated, a young cuzco, but the spines seem a bit thin....

 

I find that trichs really seem to change form....even from clone to clone.....I believe change in environments effect appearances greatly....

Greetings to all. So i have a question for anyone of you that is familiar with L.W. Caespitosa. How often do you water yours?

Not at all in the winter months....usually about 4-5 months out of the year, completely dry.....then when spring rolls around and those chilly nights are just about over, I'll give mine a nice thorough drink, and then maybe again in 3 weeks time....once it starts heating up and getting really hot, like june-july, I'll water every 1.5-2 weeks depending on soil dryness....as fall starts setting in, I'll back off to once every 3-4 weeks and once that first 45*F or lower night hits, i completely stop watering....hope that helps....This is of course for outdoor hard grown yotes....

 

Indoor, under artificial lighting, I would give a nice drench every time the soil was bone dry

It's a torch, but also a San Pedro...if you know what I mean.
