growing rosemary indoors
Hi all. So I know it's said the rosemary cannot survive indoors....nor outdoors in a pot in a Zone 6 environment.
So I have chosen the lesser of the two evils, and am trying to keep my rosemary plant indoors over the Winter. I have the pot sitting slightly elevated over a dish that is constantly filled with water. I give the plant a very fine mist of water almost daily. And my apartment never gets hot due to heat in the Winter. I prefer to keep it cool and even when the heat does come on, it's a very subtle dispersed warm heat (not steam). I keep the rosemary sitting in front of my glass balcony door so it can get the most sun possible.
Anyway, I have noticed like a white powdery film on the leaves...mainly more on the inside part of the plant where it's obviously more densely packed. It's not like a cottony film...but more like a powder. When I rub the leaf the powder comes off pretty easily.
Any ideas what's causing this? Maybe I should not be misting the plant unless I simultaneously have a fan running to help the mist dry off the plant....maybe that's what's causing it? Obviously I can't run a fan 24/7, but maybe instead I could mist the plant and then put a fan on it for like an hour or so after to help the mist evaporate?
