My tissue culture D. hartemeyororum

[David]

Just sharing my new "pets". Taken them out of the tissue culture vials last weekend. The original leaves (reddish colour) seems to have died down but in it's place new leaves (greener leaves). Looks like this species is quite a fast grower. Quite happy about that. Now to try to get it to turn all red.

Just to avoid misunderstanding, the media is not all course sand. That's just the topping. The media is about 2 parts sand and one part sphagnum peat.

David,what's under that sand? How deep is the sand and is anything else mixed in? I ask because my TC D. hartemeyororum just wasted away (melted down is a better description) ...although it may have been bothered by the long transit time to begin with. I worry that I was keeping them too wet when I see yours. Good luck with them!

Ops! I just edited my thread to include that info. Only saw your info after I re-post

I think being wet is not the problem. My pots are place in about 1cm of water and the media inside is wet. I still have a plastic clear cover over the whole plant at the moment to keep it very humid. Just removed it for the picture.

Thanks David! Well, I did 'tests' with 1:1, 2:1, 1:2 peat:sand and a few with finely chopped sphagnum in each of the above. The D. harts all melted down so it was probably the transit shock.
I'm doing similar tests with germinating D. intermedia "Cuba" and the seeds on pure sphagnum have been up 3 days now and still no sign of any on the peat or peat:sand. I'm sure they will follow but it'll be interesting to see just how far behind.

I am using sand/peat (4:1) mix. This is fully hardened to my balcony conditions but I lost a couple when the weather suddenly turned hot and dry just for one day.





Try and spot the yellow glands!

Cindy, yours have become very bushy. Can't wait for mine to grow like that. Did your plants also loose its original leaves (when it was in the vials) after taking them out of the vials? But it's cools huh when they replace that with a few new growing points.
