My poor hoya
I am not very much of a green thumb, but I bought a hoya carnosa for my girlfriend at the end of the summer in August. It's beautiful with all sorts of pink flowers and it has been a pleasure in the apartment. I must admit, however, that I do not know what I am doing. At first I watered it every other day, but it seemed like I was over-watering it. Then I tried to let it dry out well enough before I'd water it, but I think I may not be doing it frequently enough. It has withered to about half the size it was when I got it, but I don't want to give up on it yet.
I read that I should let the soil dry out, but I'm assuming I shouldn't let it get too dry? Is once a week a decent amount of watering for it? Also, I was reading that maybe I should get a spray bottle and just mist the plant (especially during these winter months). What is the suggestion from the experts?
