Afid -
Be patient. Now and then a flower gets "knocked up" either by self pollination or by the activity of insects or hummingbirds. Usually I just clip the pod because I don't see the point of...

I saw those... but if you look at the photos carefully, you'll see little white threads. Not only on the underside of the leaf where the dead bugs are, but also the middle photo with the aphids and...

First, at those low levels I doubt that my meter is particularly accurate. I look for changes more than an absolute value. The other may be the specific membrane design (my unit is pretty efficient...

Probably so, at least close... at least to the genus level (an ID to the specific hybrid would be impossible) There may be some other member or members of the Oncidium tribe in there too. In any...

Those little white "threads" might be immature aphids... I have seen those when I had those "aphid attacks". At any rate, your treatment will kill any of these pests.

It looks like an Oncidium tribe intergeneric. Maybe quite a bit of Odontoglossum in its background??

You can alternate with soapy water, or Neem... I have found that these sudden infestations go away as fast as they come. (When it's in the house especially annoying... but I have had that happen too)

About the ratio that I work with... a new membrane gives me about 10, about the time that the production goes down drastically, the TDS may be up to 20 or 25. Not a rush though.. it is still, at its...

Looks a lot like Miltonia moreliana (used to be Miltonia spectabilis var. moreliana, now its own species) or could be a hybrid of it. Impossible to tell for certain from a photo because there are...

I don't know what the "trigger" is, and I don't think anybody else really does either... many of these come from equatorial areas where the photoperiod is pretty much the same all year. Somehow they...

I grow my Catasetinae outside during the growing season (they take up lots of room), but I keep them in the greenhouse when nights are much below 55 deg F. Even when they're...

I don't even cut back water particularly on my Bletillas - the ones that do best are in the ground, so they get watered with the landscape plants and rained upon. I wouldn't worry about their...

Totally random, as far as I can tell... these variations on each of the two plants are in the same blooming... next blooming just as random. It's just what these species do.

I don't have a photo of Phal. tetraspis with multiple flowers, but here's Phal. speciosa. I think there's 2 or 3 spikes, 2 or 3 flowers on each spike. All different.
