Catasetum culture
I posted two photos of a Catasetum pileatum in ABPO under same subject line.
As you can see, the leaves are yellowing. The second photo is of the surface of the plant to show that the roots are looking well, and that the bulbs are nice and on the plump side. My questions a I- Is it this time of the year when the ctsm's start to shed leaves? if so, is this when I stop watering it completely? II- It stayed pretty much in full sun all summer, and took it very well, the leaves were green up until Friday of last week. If I keep it in darker conditions now, withold water until new growth appears, give it a drop of about 10 to 15F at night, and about 74F during the day, from now until spring A: When can I approximately expect it to send out a spike? B: Will it produce male flowers? III- And if it's not that time of the year, then can someone clue me in as to what's going on with this orchid? Very thankful for any tips & assistance, Mariana |
Does no one else grow Catasetums on this board?

This is the time of year for some Catasetums to lose their leaves. When
this happens will vary with different species. In "The World of Catasetums" by Arthur Holst, he gives the following info for C. pileatum: Flowering is mainly in Autumn, although plants may flower at any time. A bulb can produce multiple spikes. This species is accustomed to hot, humid conditions and may only need a short dry season. Some plants that come from Venezuela's savannah will have a longer dry period. Provide a winter rest if the plant's appearance indicates a need for dormancy. If you like Catasetums you may want to get this book, it's not very expensive. -danny "GrlIntrpted" wrote in message t... Does no one else grow Catasetums on this board?

Does no one else grow Catasetums on this board? I do... A few, anyway. I used to have more, and probably will again very soon. Problem with answering the questions below is that it is very variable. I can't see the pictures, but if the plant is otherwise healthy looking and the pseudobulbs are big and firm, then you could be dropping leaves any time between a few weeks ago and January. It gets really wonky if you grow under lights - no guesses then. Some catasetums, even normally deciduous ones, will not bother dropping their leaves if they don't get the right signals. Most seem to bloom normally regardless. I still haven't figured out which conditions give male or female flowers. There are a few schools of thought on that. I suspect this varies by species as well. I wouldn't put it in a darker spot. Or at least not a lot darker. A lot of people unpot them when they are dormant, and repot them when the new growths come out. I've never bothered with that... I've never been particularly good at withholding water, either. I'd water them a lot less, but if the pseudobulbs start to crinkle up I always give in and give them a little drink. You should see flowers in a few months, I'd guess. I think my pileatum blooms while leafless. That may be variable in the species. I do know that mine always used to bloom back into my tiered benches, into a wire mesh. So I'd never know it was in spike until I snapped it off. I don't grow on those benches anymore.... I'd really recommend the Holst book on catasetums, if you are even mildly interested in the genus. It is excellent. Rob "GrlIntrpted" wrote in message .net...

It gets really wonky if you grow under lights - no guesses then. The p/b's a very firm, the roots are out of control (root growth upon root growth all over the surface, it looks like white grass on the surface).

I'm hoping to get some male flowers, aren't they showier? I wouldn't put it in a darker spot. Or at least not a lot darker. It spent the summer in the outdoors (well the spring too), I'm thinking of moving it indoors and to let it sit on the Western exposure side, in the pot as is, and if it shrivles up I guess i'll mist it, but it's fairly dry at home, and around 74F, at night we drop it to around 68F. Can it still stay outside? I'd really recommend the Holst book on catasetums, if you are even mildly interested in the genus. It is ) Your response is greatly appreciated Rob, thank you. Mariana |

The leaves are showing yellow streaks and some brown/dry marks on the outer ridges. Probably just normal deciduous leaf drop then. Spider mites will also cause the leaves to yellow (starting at the tips, at my house). Spider mites are a pain. I'm hoping to get some male flowers, aren't they showier? As with most species, particularly primates, the male is always the showier and more desired phenotype... *grin* Female catasetum flowers are interesting. But not what you are looking for, most likely.

Can it still stay outside? As was already noted, this is supposed to be a relatively warm grower, so I wouldn't take it down much below 50 if I could get away with it. While dormant, it won't care too much about the cool temperatures, as long as it is kept dry. You could probably get away with temperatures in the 40's overnight a few times.

I heard that Kelthane works! Especially made for spidermites. Male & female flowers? I would be happy with either!*G* -- Cheers Wendy Remove PETERPAN for email reply Rob Halgren wrote: GrlIntrpted wrote: snip Probably just normal deciduous leaf drop then.
