phrag grande repotting

[weederwoman]

The two parents both grow in nature on limestone cliffs near seeps, although sanderianum can be found in tree crotches, says Baker. It will need frequent repotting (do paph roots stick to terra cotta?). I want to translate this into best practice for a greenhouse for something that will get so big. Eventually it will need a large deep pot, I am thinking, with very open mix since large deep equals easy rot. Just wondering if anyone has grown a large sized plant and has tips from experience. Mine is a youngster. Thanks

Yes paph roots will stick to terra cotta.

What kind of medium is it in now, and what are you thinking of using? Do you have a photo of it?

I've had it two some years. Time to repot. Its in a small terra cotta pot in a fir/perlite mix with a small amount of shredded spag. Topside it seems to be healthy. I also have a magic lantern and a Ruth Wright x primulinum that are young that I got at the same time and that are potted the same that I'm about to repot. Three big box maudiis that I've had a year or so longer that are flowering size to repot also. I plan to switch to plastic because of root stickage, but use basically the same medium. I will have to put the plastic pots inside clay pots, since all the plants in the greenhouse are potted in clay to give uniformity.
