dry rest for paph malipoense?
I just read that paph malipoense grows in monsoon conditions where it gets a
cool dry winter. Would it be a good idea to give a paph malipoense a dry rest period, or at least to reduce it's watering? Currently I water my paph malipoense once a week. Would it be a good idea to water it only ever other week in the wintertime for example? I have read this as a suggestion for paph bellatum culture, and now after further reading it seems to me like a similar strategy might be applied to paph malipoense. Has anyone tried giving this paph species a drier winter? Is there anyone out here who has gotten a paph malipoense to reflower in less than geological time -- I remember when I first got the malipoense someone suggested that it only flowers in geological time, and I wonder whether this might mean that it should be treated somewhat differently from other paphs to get it to reflower. The other suggestion that I have read was that paph malipoense likes calcium-rich fertilizers. How much of a difference do you think that would make? My paph malipoense has a healthy new growth that is currently growing a new leaf, so at this point I think the plant is healthy, and I would not want to jeopardize that, however I would like to consider adjusting its culture to encourage reflowering, if possible. Thanks, Joanna |

Hi Joanna,
I have pretty good luck with malipoense, but I am not sure how helpful any of this will be since I grow in a greenhouse. I do not change the way I water, watering when the mix is lightly dry. But, the time required for the mix to dry does change with the seasons. Late spring/early summer it dries in as little as four days. Midwinter it may take 10 days or more for the mix to dry. Most of my Paphs, including malipoense, have a blooming season. I do not remember when malipoense season is here, but my plants were just a couple of weeks ahead of when yours bloomed last. Do you remember when that was? I put a pod on one and did not date it because I was sure it would not take. The 'pod' is looking about ready, but you know about looks being deceiving. Around here fertilizer is a binary thing, you get what is in the tank or not - no special diets. I do use a calcium-rich fertilizer in the fertilizer rotation. To get extra calcium to the Paphs I add crushed oyster shell to their mix and when ever I am spreading dolomite I try to throw some their way. Paph are pokey. Watch leaf sizes, it is not ready to bloom until the leaf span on the new fan is at least as big as the span on the fan that bloomed last. If the last blooming was a first bloom, the new fan will most likely be bigger than the old fan before blooming. No need to try to make it bloom before its time. I have never forced a Paph, but I expect its clock is timed to length of day or temperature. Pat "J Fortuna" wrote in message news:3YG%e.3215$kl3.1525@trnddc08...

Pat,
Thank you for your reply, and good luck with the pod on your malipoense. According to my orchid database, my malipoense started blooming on February 11, 2005, but it was in spike in mid-September last year, so if it were to rebloom this year, this would be the time to respike. (However, I bought it in spike, and I am sure that the conditions that it lived in at the vendors were quite different than mine, i.e. greenhouse. So maybe the last time it spiked is not a good indicator of when it will spike again.) The new fan, which the malipoense acquired in my apartment, is bigger than the previous fan already, so that's good, and it is currently growing an additional new leaf in this new fan -- but it is clearly a new leaf not a spike. I think the problem for me is that this paph is in a bark mix in a non-transparent pot. I can tell when an orchid in moss approaches dryness by touching the surface. I can tell when an orchid in a transparent pot approaches dryness even if it is in bark (because I observe the moisture on the inside of the pot). But after 4.5 years of growing orchids, I am unfortunately still incapable of telling when an orchid in bark approaches dryness unless it is in a transparent pot. I know the theory of how one is supposed to be able to tell, but I have trouble with it in practice. So I have been watering this malipoense once a week for a year now, and it has been growing a new growth, so it's not bad, but I think that what I have been doing may not be enough to get it to reflower. On the other hand two other paphs that I have have reflowered for me under similar conditions and also being watered exactly once a week -- and one of these paphs has been reflowering twice a year (both fall and spring) and it is getting ready to flower again. So while I know that my treatment of them is not what is recommended, it seems to work fine for them. However, I suspect that it may not be enough for the malipoense. We will see, if the malipoense does not spike this year, maybe I shall repot it into a transparent pot in order to be able to tell how to adjust the watering seasonally. Crushed oyster shell and dolomite. Hmm. Maybe I should look into that kind of addition to the mix. Thanks for the tip. I look forward to the orchid show at the National Arboretum this upcoming weekend. I saw that Brennan's Orchids will be there. Last year I bought a Phal from your stand as a present for a friend, and she has been very happy with it. When I told coworkers that the orchid show is this weekend, they asked me whether I was going to behave, and I said that I will try hard not to buy every orchid that I want. :-) Thanks, Joanna "Pat Brennan" wrote in message ...

Joanna,
I checked my malipoenses and they are in very low spike. The pod is cracked. I lose control of things in show season. I would guess the trigger was some function of temp. This time of year nighttime greenhouse temps get much colder than inside a house. Hopefully your is only 4 to 6 weeks behind. Pat "J Fortuna" wrote in message news:2%m0f.214$yN6.38@trnddc04...
