Thank you for your message. I already read this here in the past about Didymaotus: Steven hammer says that those plants love a heavy clay soil. However, I'm afraid, if I add some clay to the substrate, to get a mixture too compact to keep their roots alive...

What kind of cat litter do you use? Sepiolite (clay) or diatomite (silica)
To all, Happy New Year 2018 and great success in your growings
I know this thread is a little old, but regarding Muiria, in this video, the gentleman talks about adding a few grains of salt with each watering.
I do not know the physiological reasons behind this practice (other than possibly to mimic habitat soil conditions), nor do I know if this applies to seedlings.
I wouldn't worry about it for the seedlings, but salt seems to help the adults stay fat and happy without needing so much water. Not sure how that works. There are reports that gypsum does much the same thing.

Maybe there is some truth in that. My two Muiria's of almost flowering age suddenly dried out as if they were going dormant. They got an almost weekly watering as they have had for the past seven years. Luckily I still have two pots with both one plant of another batch of Muirias, of which one is also of maybe flowering age. Maybe I should start adding some salt to the water...
Does anyone know the MSG bulletin number mentioned by the man in the video that Magi posted, where the article mentioning the addition of salt when watering Muiria hortensae can be found?
They are so red!
