Hi,
I bought this den nobile today.It has lots of keikis, actually the keikis have keikis.I noticed black discoloration under the leaves where it attaches to the cane.Some leaves have it and some don't. I took off one of the flowering keiki and it has the same thing.My gut feeling is telling me it is infected with something.Any advice would be appreciated.Thanks!

Comments (9)My option is yes, you can root it. I personally have not done this but have read about it a number of times. Just take the cane and lay it down on a bed on spagnum moss. Keep the moss SLIGHTLY wet (maybe damp would be a better word) and the cane should produce roots at the nodes. I've heard of people breaking off a cane and breaking it into pieces in order to produce idential plants. Good luck, and let us know how you make out.

Comments (14)The dark box? Seeing no one else has answered, here is a bit more. Think Neighbours, there are 300 sunny days a year and if the day is sunny the sky will be a searing blue, not that wimpy moisture laden wishy washy blue UK sky. Spray the roots daily? you jest. I've only got three plants but they flower every year without fail. They are in a shadehouse down the backyard. 50% shadecloth in winter. Two layers of 50% shadecloth in summer. They are exposed to the wind and rain. Average temperature 7 to 17C winter. 17 to 27C summer Low for the year 1C high for the year 40C. They are tough. No fertilizer from mid autumn till they flower. No watering except for natural rainfall during winter. It does rain, sometimes lots in winter, sometimes it might not rain for weeks in which case the plants might get a meagre squirt or two from the hose, i don't believe this bone dry stuff. If the prevailing winter westerly wind is blowing the humidity will be low. So, those Dens are out there where Phals cark it. Forget all this tropical stuff, they are not tropical lowland orchids. Think of the two seasons. The warm wet and the cooler drier and you might be on your way. To answer your question you should let the medium dry out to just damp before watering again. If you get the new growths to grow after flowering you should keep the plant warmer and increase watering and fertilise. (though i'm not sure how you get the plant back on track) Sorry that i cannot tell you exactly what to do....you have to interpret what people write here and try and adapt the advice to your conditions....See Moreperplexing den. nobile
Comments (16)Sav no i grow everything outside. Dens of all types are grown in full sun. Temp is the key as to whether or not to water nibile types. If you have temps in the low 40's consistantly for a month or more, then you can water less then summer, sparingly. If you are growing warm and continue to give water they will keiki instead of flower. keep dry until the actual buds form, they dont have to be big, just big enough that you can tell that they are flower buds. then start watering as usual. I have many nobile types, and they set bud at different times. My Den. Super Star 'Other Worlds' is just at the point that I can see the actual buds. Next week it will go in an area of the yard that I keep well watered. Others like Oriental Smile 'Fantasy' show no signs of anything yet. and as for my soft canes, anosmum, pierardii, lodigesii, will get not a drop either until buds form....See Moreshavedmonkey (Harvey in South Fl.)Z10b
