Mokara Chark Kuan[gold] on S/H

[Ray]

Paphs were the first plants I tried when developing the culture technique, and the did so well, it encouraged me to try others.


I would say the the most significant factor leading to "S/H Failure" is poor timing for repotting.

Even if I grow Vandas on S/H, I still spritz the aerial roots and the top layer clay pellets. I just depend on the water level for humidity. I cant just leave it alone for weeks. I still feed it weekly and flush it once a month. The real advantage of S/H on Vandas is that you can monitor the roots grow and as the plant grow tall the weight of the pot is stable. And Vandas want that, since they tend to topple down.
* I have a Renanthera citrina newly posted and it is also in S/H method growing well for me for the past 2 years.

I will add that I cannot grow a vandaceous plant in S/H at all.

Thank You for your input, Ray!

I find it strange that Vandas don't grow well for you on S/H method. I put all my Vandas outdoors in the warmer months and just hose it every other day so maybe it is also that factor of added watering that sustains my Vandas on S/H.

Right, all my orchid plants on S/H seems to love it and grow well for me.
Aside from the culture, make sure you treat the plant as if it is in its native habitat; taking into consideration its extra needs.
Some Vandas grow in trees and some of them grow on rocks near river banks that sometimes in the monsoon rains get them flooded and under water for weeks.

I observe my orchid plants for a couple of days after repotting on S/H. If they perk up then it means they have adjusted to S/H well. If they wilt then I put them back on the potting mix and try again when they get used to my environment and produce new growths and roots.

Ray, you must be right re: the Renanthera. I do think it must have been my timing because it was a very healthy specimen when I received it.

With Paph it could have been timing too but I suspect it might have been in compromised health when I got it.

But given only two failures out of forty or fifty pottings in S/H, I like those numbers!

Don't call it a failure. It was merely wrong timing. Had you known ; you could have done something about it.
