I used cactus mix w/ perlite added for mine. It took awhile. Yes, i added extra perlite to the mix. Use at least a three-segment piece, and bury one segment. It may take a month or two to root.

Even vermiculite may not be the best ingredient - it does 'fall apart' after a while. Plants will not die immediately if planted in what you are using right now, but for long term and better plant health, think about getting some grit, or scoria, pumice and possibly turface, and perlite that you already have. Obviously, it depends on what is easily available to you, not all of the above have to be used.

If using sand, make sure it is very grainy. It may be good idea to sift some of it thru ordinary kitchen sieve - and use only what stayed inside of it. Particles falling thru are most likely too fine. Sand has tendency of filling all the spaces available, and impairing the drainage.

Use Orchid Mix or bark, perlite, and a pinch of potting mix....you won't be sorry.

I have mine in orchid bark. I've read that they like moist humid environments like orchids - but not to just be wet. There is a difference. Even if you have other stuff in the mix I would recommend making a well aerated mix.

I forgot! I do have Orchid Mix! I'll try Josh's recipe. 2 days they've aired, so I will put them in this mix according to bragu's method. Thanks all!
