Oh geez ------ fuerte rav ----- if I lived next door to you, I'd never have to buy potting media ever again hahahaha.

Fantastic photo. I love the scenic look where you live. Wonderful.

I think scoria can have lots of forms - as volcanic rock is sort of general, but maybe the ones being sold for orchid growing have small little pockets all around ---- that can hold a little water for a while --- but not too much. But the combination of the scoria in the pot can allow the pot to stay humid and damp --- even a little wet --- for a while, and provide orchids enough water to grow nicely.

The scoria I use is locally called quincan gravel ---- pronounced kwing-kun gravel. But people call it scoria too. Some edges are a bit pointy, but never knife sharp. The type of scoria over here is no problem for grabbing with the hands - won't cut skin etc.

If it doesn't cut into skin - the type here ----- then it's ok for orchids. I can take some close-up shots today anyway ---- some good sample shots.

Hi ES! I've seen some youtube videos - time lapse videos of some growers propagating the variegated monstera plants from node cuttings.

I have a feeling that it might be better to have one big massive plant and then take lots of node cuttings (stem cuttings that have a node in the middle), and then attempt to propagate.

I have a feeling that some node cuttings may not grow - even though they're node cuttings. But if there's several (or lots) of node cuttings --- at least some will grow and make it.

So 1 stem node cutting having initially no rooting activity or bulging activity or anything ----- will definitely be a gamble. But many cuttings ----- definitely will lift chances of at least some becoming active and making it.

This nice video made by somebody is quite nice to watch. Just pasting the link for you ES - click here.

The plant in the pic came from a stem node cutting. It's got a good set of roots. Properly established - a proper plant now. I purchased it on ebay.

My ebay strategy was along the lines of ----- safest to purchase a rooted stem cutting - preferrably with leaves coming out of it too, or at least some sprouting activity.

I don't actually like those sellers on ebay selling 1 single new stem node cutting for hundreds of dollars.

It's not due to the 'price' as such. It's due to the possible waste of our money to give them a few hundred bucks for something that could possibly not actually grow at all (eg. waste away, rot and go soft etc). It's probably nicer if us customers pay some price - even if relatively high - but pretty much guaranteed to just go and grow.

Another strategy that I thought of ---- could be to purchase a stem node cutting from a nice ebay seller. One that appears trust-worthy and nice. If it doesn't grow, then to message the seller very diplomatically and nicely to ask to buy a successfully activated node cutting (with activity - roots and expanding node etc). That could work too - but definitely requires a nice seller and customer relation. Some ebay sellers can't be trusted for sure. They ruin it for the many really good sellers out there.

Also ------- one possible thing for ebay buyers to ask a seller is whether or not the stem node cutting has those outgrowth features (for the new leaves to develop).

From that same time-lapse video, it's noticed that the stem node cuttings that were eventually successfully propagated ------ all had those buds on them.

The remaining one didn't do anything or much at all ----- but still shows some hope of growing (because it didn't rot --- didn't change to black coloured over the duration of days). Not sure whether that last one actually made it. I wouldn't be surprised that the last one didn't actually make it - even though I think the person making the video mentioned something about a swelling or bump developing later.

Below is a screenshot (image) of the youtube video frame.

Those outgrowths are the node! In more proper terms, they are "axillary buds".

That's the only spot where the new shoot will grow, without it a stem cutting is useless and will only grow roots.

As some rare variegated Aroids cuttings can retail for a small fortune, better be very careful. Scams are legions.

MFN ----- oh cool! Thanks for commenting about that!!

I previously assumed a monstera node as being the tan/brown woody portion between two green sections of the stem. And I think my assumption is actually correct - as in a 'node' is the intersection of two green sections ----- or rather, where a base of a leaf used to be, or where the leaf was once connected.

But - it appears that those extra features - actual nodules that look like outgrowths ------ are critically important.

This is good, as that will help buyers to really beware of ebay sellers that sell stem cuttings that don't have such outgrowths. Thanks MFN!

I personally would steer clear of sellers selling cuttings with no axillary buds (lateral buds).

Another nice link too (click here).

Default Monstera node cuttings and axillary buds

Just uploading this image here, which I added a few things to - relating to Monstera cuttings.

We have Molida (ground fairly small, we use it instead of sand for horticultural purposes as our local (shell) sand is too fine)
then Picón (pea sized pieces. The spawn of the devil, gets in your sandals, agony, sticks in soles of shoes and scrapes floor tiles, gets in pet's paws - won't have any in my garden!)
then Grava (2 - 3 cm pieces, my heap!)
then Grava grande (4 - 6cm pieces)
then Piedra negro : large pieces for building garden walls etc.

Grava:


Just dug out my last bill. I had 8 cubic metres delivered, 100€. And 40€ of that was the delivery, so about 7.50€ per cubic metre. (That was the 4th delivery in 4 years!)

I've got 2 phals needing repots once I see signs of new root growth so I'll give it a try. I'll start soaking and rinsing some Grava, not sure where on the island this particular batch came from, might be a bit salty.

Also very interested in the Monstera info. I didn't realise you could get variegated ones, never seen them, but love the look of them! I've got a basic green one that's got a bit leggy so I'll have a look tomorrow and see if I've got suitable bits for cuttings - a new project!

Fuerte rav ------ I think your kind is about the same as here. Ours often have extra dirt/soil stuck to it, which isn't fantastic - but it's ok. Your 2 cm size should work excellently.

The kind I use is exactly like in this pic link here: (photo link)
and will just upload it as well in case their link ever changes.

Can't remember ever seeing so many rainbows as we have had this past few weeks. Just wish we had some rain along with them - all we're getting are a few odd spots that don't even join up on the floor.
