Question about rooting stumps and pupping

[hostilis]

Well the right side up cuttings will be normal, but upside down cuttings will do what I'm talking about. I've done it with pereskiopsis accidentally in the past (planting upside down) and the pups came out pointing down then did a weird curve to go towards the light. It's just a physics thing the way the plant pups (on top of the areole) But I've never done it with a trich so I can't say for sure what would happen.

as trichocereus cacti and most other genus wont root upside down but will rot.

Billy, you are mistaken.

Upside down planted trichs can & will root & pup, albeit in a much longer length of time than if planted right side up. Been there, done just exactly that.

Just because they may rot for you does not mean they rot for every other person.

Here are the pics of the T. Bridgesii that is rooted upside down with 2 pups coming out normal looking. No weird physics ;)

Are you completely sure that's planted upside down? I swear on the first 2 pics it looks like some pretty clear V notches above the couple of upper areoles closest to the camera...

I put a couple of circles around the areoles I reckon I can see the V notch the clearest in the photo below.

hm i see what you are saying. im pretty certain this was the bottom 12" of an arm though.

I had a lot of confusion with this guy on the left for a while i'd just never seen spines growing up like that. Always straight out or down but never upwards like this one.

[magical9]

heh yup . i had that problem with the zircon6 cuzco when i cut it into pieces.. i forgot to mark the ends lol so i couldnt tell . had to check the ebay pics! spines shoot upwards!

Question to ya'll... during off season(winter).. if i try rooting stumps indoors in a grow tent with lets say... a 400w HPS lamp and air temps of 95F ... would the stump root and continue growing? Basically is there a way to keep the cactus growing without stopping for winter break?

[djmattz0r]

Yes you can keep a cactus growing through winter with something like that, but some people say you should allow a cactus to go through it's dormancy phase.

I figure some climates keep cacti growing year round because of warm temperatures though so I don't see why it would NEED it.

[hostilis]

You could bring them inside to grow but they would probably just get etiolated as hell.

[djmattz0r]

a 400w HPS would probably be enough light but a MH would be better for keeping cacti growing and limit etiolation.

look if the thing doesnt decompose its gunna grow!

dont matter if its upside down wrong way out hell bent on frizzleepops!

fact is decomposition is growing so if that dont sum it up?

they grow exact same rates upside down, right side up and completly fucking sideways...

your veiw of asthetic change makes you think otherwize.

@magical9 you'll actually get better growth during the growing season if you let them have a dormancy. Without it they grow at a slower pace all year long

[EthnoGuy85]

FWIW IME the log method takes ages longer and doesn't produce any more pups than planting vertically.

good point. ya i was just curious about doing it over winter just so i could get a jump start on the season since these stumps aren't rooted just yet. BUT ill just let nature do its thing at its correct pace.

It might depend on the size of the log. I planted a 4 foot Pachanot tip cutting on it's side last summer and it now has the original growth tip turned upwards and I think at least 7 pups growing along the length of it. I think unless I cut it into about 4 sections to plant upright I would not have got that many pups.

Granted, the 2 bridgesii that I planted sideways were only about a foot long each and they have pupped 1 and 2 times each respectively.

[edit] - oh yeah, the log I planted horizontally started to pup way down the bottom within a few weeks of laying it down. Didn't take mine long at all. The bridgesii's probably took about 2-3 months to pup on their sides though.

Hmm, I dunno, even the glaucus growth marks make it look like it's currently right side up though....
