Trichocereus Terscheckii Growth rate ?
#19212621 - 12/01/13 01:03 PM (10 years, 2 months ago) |

I have several terscheckii of various sizes. I have 2 that are said to be around 6 years old , but one is tiny and the other is about as big as a teenage barrel cactus and is just now starting to grow upwards. But my real question is about old terscheckii , because i know seedling growth rates can vary drastically .
For instance i have heard that once they get over 2 ft they take off and can grow up to a foot a year . Is this this true ? That seems extremely fast compared to young terscheckiis . I have found a nursery where i can buy several old specimens some over three feet , how old are those likely to be? I can upload pics if Necessary

Terscheckii is growing very slow to cobular and get fat.
Growth rate depends on climate, growing period length and so on but I found some site from gardon grande cactus where was pictures and years below it.
So in habitat they grow "hidden" as cobular 10-15 years, at age of 20-30 years they are 1-2 foot columnar cactus and +50 years they should reach several feet length.
I have not seen myself a big terscheckii, but they slower as small and speed up growth.
I remember I read when I "study" this plant an google it and I found information said at +1 foot height column in habitat starts to speed up a growth rate and if growing season is good for old big cactus, I think approx one foot growth in year can be possible when cactus is big and old enough.

I'd guess those are 10-15 years old maybe even less. Once they start growing columnar they grow pretty quick (at least those in the ground). You need to remember that in cultivation they grow quicker if you fertilize and water often.

Ok that makes a bit more sense . The price seemed extremely low for a 30 year old cactus.
Thanks MS

You maybe miss my point..
I don't speak about growth rate of this cactus in human cultivation. I mean information I have read about t. terscheckii in their habitat and these were estimated sizes and growth rates.. I am sure I say word "habitat" for you.
In habitat there are not identical growing conditions every summer nor perfect fertilizing and watering periods. It can take long time in habitat to this cactus to even reach size of football.
There can be bad summer or good summer, if cactus is young and small and it's cold summer, one year growth are not much compared to specimen cultivated by human.
I have seen also a french nursery site where was ~1,5meter(5foot) t. terscheckii at price of around 800€ if I remember right.
It's a fact about all cactus plants their growth rate is slower in habitat compared to human cultivated specimens. Human can boost growth by giving water and fertilizers more frequently and if greenhouse are used human control whole climate of plant.
I maybe write wrong but I talk about possible estimated sizes of this species growing in habitat and most of the time goes when cactus is young and grow slow. Also extreme drought during growing season decrease total amount of annual growth and this is not happening when humans cultivate cactus cause they got water and feeding at regular basis.
I was not answer directly what is the growth speed of cultivated specimens but only I know they speed up a growth when they change appearance to columnar.
In habitat this cactus can be small cobular plant over 10-15years before it starts to grow columnar form if cactus happens to be at spot where fertilizers and water is very limited. Afaik good human cultivation can speed up growth so much this cactus grow to big cobular in 4-5years or less and starts to grow columnar and fast way more faster than cactus in habitat. There are also differences of habitat, some can get good spot, some specimens not so good.
Even in human cultivation, if cactus is not taken care of and human don't care plants and lack with fertilizing and watering, this cactus don't grow so fast and stay long time as small cobular.
I have one good example about human and growth speed of cactus: I give two approx 5-6inch trichocereus peruvianus cactus to my frien and I said they double size if taken good care of plant. Then I ask year later how these cactus plants has grown so he said they are not growing so fast as I have said. So I find out he barely water nor fertilize them they have grown only ~1inch in 12 months. Compared to my trichocereus plants what usually double their size in that time.

Oh ok. So this is probably the problem with my little terscheckiis because I have barely fertilized the all.

Just don't use a super high synthetic nitrogen source like miracle gro or whatever. I much prefer to use slow release organic meal based fertilizers like Dr Earth, EB stone, or Whiney Farms.

So do they have One Specifically for cactus? I've been using cactus juice and it works pretty well . Would it be good to switch between fertilizers During growing season?

Yeah 1 7 6. However I give my PC pedros shultz 2_7_7 They seem to do good with a little more nitrogen , i would guess its because the american clone grows so fast so it Isn't as prone to splitting like a slower grower. I even used regular fertilizer on them when i was a newb and they did fine. I think the low nitrogen intake Applies more to Cactus like echinocactus and lophophora , at least That's what i have picked up from the Corroboree , but they probably grow a lot faster in oz ...

These can be hard to estimate ages of. One could easily have seedlings that take 10 years or more to start going columnar, and then their vertical growth is still fairly slow, but in terms of mass they will then soon start to pack it on.

Like there are said, there are different strains of this cactus. Also growing conditions, soil, fertilizers and watering define the actual growth. env Also like I wrote, I can manage to grow trichocereus pachanoi/peruvianus/bridgesii over 12inch in year or if smaller they double their size or more. Compared to peruvian torches I give to my friend, he as got 1 inch growth in one year.. so he have different soil, different environment, watering periods and fertilizing.
Anyway, mostly_harmless is right with terscheckii, these are very hard to define age from their size and if you add there everything I mentioned from ferilizing to soil how much it allows watering.
I have some terscheckii also, don't know ages but bigger one are probably at age between 7-10years and younger one is few year old slow grower probably age of 2-4years. Smaller one was very small when I got it, now it's bigger after one year but I don't know how old these plants has been when I got them.

I have also t. pasacana.. My plan is just to grow them to nice big columns to ornamental plants indoors. To get their shape perfect I keep them in greenhouse over summer and rest of the year at windowsill.
Soon I got apartment with massive corner east-south window.. Perfect for cactus! growing over spring and fall because even with greenhouse I have maximum ~4months (or some weeks more) season outdoors assuming I use electric heater over night. Without heater I have greenhouse season ~3months. Anyway, that time I can get nice appearance to cactus and rest of the time at nice very sunny windowsill where I can bake the cacti in sun.

yeah. Its what it is. I think they got watered 6 times in the past 2 years. Wasn't home during the growing seasons the past 4 years really. I'm not planning on traveling this next season so looking forward to a good grow. Was happy to be home for the last of the good weather and nurse the kids a bit before bed.
Dang yeah I can keep my plants outside in the green house for 5 months with out extra heat. Kudos to you for rocking out in the extreme!

Could you explain the differences you see in young globular terscheckii and pasacana? The seeds I received as spachianus had been mislabeled. I think they are terscheckii. But they could be Pasacana.
