Q.30 Year Old Hoya Not Blooming
My 30+ year Hoya keeps growing branches with leaves, but only flowered once in the past 10 years or so. I attach the new shoots to other branches because I cannot hang the pot, it’s too heavy and I would not be able to water it. I wonder if I should trim some of its shoots/branches so it can get more light. Looking forward to your help, because I love the blooms and the Hoya was my mom’s favourite plant. I’m enclosing a photo of the bloom of a couple of months ago and one of the entire plant. Thank you.
