Brown aerial root tips on Brassavola

[estación seca]

In my experience brown tips are a result of low humidity or staying dry too long. It can be tricky to water a plant with lots of overhanging roots in a low-humidity environment; the wanderers need to get wet frequently, but you don't want the medium staying wet. A lot of people mist the wanderers with one or two spritzes from a spray bottle every day or so.

Well, that's good to hear, I guess. This plant was last purchased in, perhaps, 2009. It has survived in spite of my neglect. I just started paying more attention to it, and it has put quite a bit of new growth. It is on the window sill above my kitchen sink - that window has constant condensation on it with the cold weather, so it's probably the most humid spot in my apartment. I had been misting the roots twice a day, but cut back thinking that was too much. I don't think there's anything I can do to increase the humidity. It sounds like maybe this is just as mature as the roots are going to get in my care before dying back? It has a ton of brand new roots on it since I have been misting it once or twice a day.

You don't think the use of fertilizer is to blame?
