I've actually already been using dawn to try and battle the aphids, etc. This weird dust cloud issue seems to be a whole new problem. A friend of mine who owns a farm gave me some fungicide that I am going to attempt using, then I plan to release ladybugs on my porch to hopefully eat all of the bugs. Hopefully between the two methods, my garden will be back under control. Still open to any advice/information pertaining to what the dust could be though!

Hello, Imontestella! Yes, I knew this was an old thread. I brought it back! lol It is an EA plant and i have not changed the soil. I purchased it back in August i believe. I think i last watered about a month ago. I will probably water it this weekend. I know that the 8 inch pots of EA hoyas (lacunosa, polyneura, and nummulariores) can got 5-6 weeks without watering in the winter time from my own experience. I had brought 2 DS-70's in 6 inch pots and one has lost all but one vine. The other one is doing great. I just dont want to water it too soon and have it sit there rotting. The pot is getting pretty light.

household dust is an odd combination of things- and having a dog certainly increases the 'dead skin' component of it. increasing the humidity in the room is the easiest way to cut down on airborne dust- it might also cure your cough (though if you're having any other breathing symptoms, or any swelling anywhere- get yourself checked for allergies. I'm an adult-onset dander, never USED to be allergic- but now the cat's not allowed in the bedrooms any more) the ionic and HEPA filter air cleaners WILL take out airborne dust- one of my clients has the 'smarter' ones in his house that needed cleaning EVERY DAY for the first few months he had it, and then it started catching up with itself, and now they get cleaned once a week, and even the plants look healthier.

Seen this many times, it's just excretions from the hydathodes caused by tap-water and soils that have salt accumulating. When soil is dry (time for next watering), I would use rainwater or distilled water and let the water run through several times. Or even better, if you know it's going to rain, just set it outside in the rain for a few hours. It happens to my jades in the winter from using tap water and they look much better in the Spring after some rain.
