Bayer 3 in 1 uses imidacloprid so it's a good solution.

I'm still seeing two plants in one pot. I honestly have never seen phals grown this way, but then again, I don't exactly have a ton of experience myself. Is there any harm in leaving them like that, or should the OP be advised to repot them into two separate containers? Depending on how long they've been together, the roots could be quite intertwined, though........

I can't see any reason to split it up. It could be two plants, or one plant that grew a basal keiki. Either way, it could end up putting out spikes on both growths... I would much rather see a larger plant with more flowers than two small, weaker plants with maybe a single spike. I can pretty much guarantee that it needs repotting, but I'd say leave it all together, remove any mushy dead roots, put it into bark, and let it grow.

Ah-ha, I hadn't thought of a basal keiki, since the two plants look very similar in size. But thanks for pointing out that possibility. :)

Usually when you buy a plant, you're buying one plant, but you do occasionally see a planter with several plants in it that have been laid out in a decorative way. They are usually not orchids, but there's no reason that they couldn't be. In nature, you could have multiple orchids near each other on the same tree or branch.

I believe some folks have purchased plants such that when they repot, they discover that they received two plants rather than one larger one. (although that strikes me as somewhat dishonest unless it was disclosed ahead of time or you thought you got a lot of plant for your purchase, but it ends up that you really got a bargain.

The mealy bugs will kill the plant if you don't get rid of them. I would also advise using an insecticide for roses. Take the plant outside to spray it.

The plant is probably ready for repotting by now. Most that are sold in bloom have been in that pot a while, and the medium is starting to break down. Most of us who grow plants in bark chunks repot every 2-3 years. The thread SaraJean and Dollythehun linked to above will explain everything you need to know.
