D. capensis turning yellow

[Cindy]

Although no Singaporean has successful managed to keep D. capensis alive

, I received some recently only to find the growing tips turning yellow within a week.

Why are the plants doing that? Btw, they are fresh from tissue-culture. Could it be the sudden drop in humidity or the sudden increase in light?

I don't know for sure, but intuitively, as you've observed, the significant change in conditions, doesn't put a positive spin on things.

Mu first capensis, I put into shock by taking it from a 21 C bedroom to a -9 C car to a 21 C lab. Within hours, nearly every leaf withered and I thought the plant was dead. So I satuarted the soil and covered it up, as well as moved it away from the light for a couple days. Then I opened up during the day and covered by night, while moving it closer to the light. By the end of the week I had it open tray and at the window sill. By that time I observed one, tiny, new leaf. 6 months later, that plant sending up a flower. This is the plant I nearly killed:

Maybe the light levels increased but not enough to turn it all the way red?
