Yes, this is a great explanation as to why some orchids - not just Cattleya for me - seem to thrive for a while then slowly decline and die out.
(or a good excuse?
)
A good example of this for me would be my gorgeous C. Chief Sweet Orange plant. I bought it at least 12 years ago, it took nearly 3 years to start blooming and for about 6 years just grew and bloomed twice a year and became the monster specimen plant it was. Then it started to go downhill, and has pretty much faded out. I rescued 3 small divisions of the huge plant but only one of them is really doing anything.
Sadly, I think my beautiful Bc. Renate is on the same path although I divided and began re-habbing it sooner in the downhill slide, I think. It was a massive specimen just a few years ago, and a powerhouse bloomer, at least 3 times/year for years.
I'm just now thinking that their decline may have something to do with having my big oak tree cut back so that the cage area was getting so much more mid-day sun! Oops! Short term, it seemed to be good for the orchids, especially the Vandas but long-term it was probably hotter for the poor old Cattleya varieties, too.
This year (thankfully) I remembered in June ! to put up my 30% Aluminet shade cloth on the west side of the cage, so things did stay cooler in the afternoons, and everyone seems to be happier. It surely was a hot, sunny and dry summer this year.
