I love my hoya. Have had some of my hoya for 20 years. The hoya in question I've had for 7 years with very little activity. Spring 2016 it formed two blooms, then a month later almost every stem took off. The ceiling in the picture is 10' high. That innocent bystander in the picture is a Christmas cactus in a hanging planter. I'm thinking in a week or so it will be pushing thru the ceiling tiles. The janitor of my office is giving me the evil eye. Can you tell me what's going on? I water once a week, fertilize 1/2 teaspoon/gal monthly. It is getting northeast sun exposure. I never move this plant.
