    Default progressively smaller growths on Delenatii K?

    In September 2004 I bought a Delenatii K . It finally bloomed 1/07. It bloomed again 1/08 and it's on schedule to bloom again by 1/09 or before. This is all to the good but the leaf spread has gotten progressively smaller. In 07 it was 8+ " last year it was about 6" and this year it's under 4" overall. It has had 2 large ( 8-10 cm) flowers both times it bloomed. I have it in a transparent pot and it has great root growth. The roots I can see are all 1/4" or greater in diameter very hairy and with healthy growing tips. Should I let it bloom or would it be to stressful for such a small plant? It is a multiple growth plant with 3 growths. In case it helps the plant is housed in a large home built growing case with 5 fans, It gets about 11 hours of 800 ft candles of fl. light daily this time of year, 68 - 72f. day time temp / 58 - 60f. night time temp in winter with 70% humidity. Summer both temps are higher but never over 80 day/72 night. I fertilize weekly with 1/2 tsp per gal of MSU rain water mix. I use collected rain water cut with tap water to get the PH to the 6 range. The plant is in med coco husk and was repotted 3/08. I'm mystified by the tendency of the plant to bloom on consistently smaller growths. Any thoughts as to how I should respond. I hate to cut off the spike but I don't want to hurt the plant.

    I'm not an expert on this, but knowing plants in general, and that you are having consistently good blooming, when you start to see the plant becoming more compact over time, it generally means that it is receiving sufficient light to maintain a small composure. Perhaps your conditions now are better than where it came from, and it had to grow larger and longer leaves where it was before in order to capture enough sunlight? And now, because your conditions are better, it doesn't need to do that? Just a thought

    It's very difficult to give an opinion without seeing a photo. In any case, if the root system is good, the plant should be ok with possibly one or two adjustments possible

    I hesitate to say too much here, as I'm hardly an expert on Paphs! I have been told, however, that longer leaves may indicate the plant needed to "reach" in order to get enough photosynthetic area, as Becky has already pointed out. Having said that, though, progressively smaller spans seem more troublesome--I'd have expected it to stabilize. I've often heard knowledgeable growers at orchid shows telling less experienced paph growers to remove spikes so the plant can focus on itself, rather than on producing (or at least attempting to produce) offspring.

    Well, I've now waffled enough! I hope someone with more confidence than I have can chime in here. I second Philippe's comment about a photo being helpful.

    Cheers,

    Rob

    photo of plant. the 3 leaves in the middle are the new plant. See also one of the roots on left side of pot near top.


    Top view showing new plant and bud, about actual size. I increased to light significantly last February. I also added 24/7 air movement and nearly doubled the RH. Prior to that, a year before the first bloom, I added 12 hours of low level fl. light but the small case I was using restricted me to 18 watts which was minimal. My current case has 120 watts of fl. light available at the top but much less down 18" where the paph is positioned.

    Is it possible that the leaves have not finished growing yet? I think the bud might be sitting there and waiting until the leaves finish up.

    It looks healthy : )

    I agree about checking the roots...root damage tends to cause the new fans to grow smaller until the plant puts out a sufficient root system.
