Hello again:
Since you have asked two questions and on neither one bothered with
"Dear so and so" or "sincerely", or "thank you" I have to wonder, if
you have so little sensitivity to those who offer you free access to
their expertise, how much sensitivity will you have to a plant? I
don't think I am being old fashioned here. I am devoting time to you,
show appreciation.
That said, ripping the lip off the flower may well have removed pollen
or otherwise damaged the flower enough that the plant is jettisonning
it. Otherwise, these green complex slipper hybrids should be among the
longest lived of orchid flowers. I suspect that in the long run,
watering twice a week will be too much, and so be careful about that.
They do prefer to get no dryer than slightly moist between watering,
but usually have a pretty moisture retentive potting mix. They also
are much more amenible to cooler and brighter conditions than either
your Angraecum or your Phalaenopsis. I grow my complex Paph hybrids
outdoors in bright shade in San Francisco, only bringing them in when
they are in bud or during very cold wet periods. Ideally they should
have overhead cover from the rain, but that is not absolutely
necessary. Cool nights will get reliable budding out of these plants
every year. If you don't have a sheltered outdoor space for this plant
(or are hesitant as a beginner to try this), you might try keeping it
nearer the window (unless it is too sunny) so it gets cool at night.
They will tolerate some morning sun on a windowsill.
As with your other plants, spraying them with water is of little
value. Most older Bay Area homes have a relative humidity of 40%-60%
most of the time, and the plants will adapt to that. A gravel tray is
much better than spraying.
Ladyslippers will thrive if repotted into fresh mix once a year. They
need this much more than other orchid genera do. And they hide their
illness like cats do. You will not know they are losing roots till
they fall out of the pot. Repotted once a year they are very forgiving
of mistakes like overwatering. In an old potting mix, they are not.
Sincerely,
Dennis
