How to make your Hoya happy

So I’ve been collecting and growing Hoya for a little while now. They’re very easy to grow and the flowers are amazing! If you’re new to growing Hoyas, here’s some things I realized by growing them myself.

  1. Hoya is a succulent epiphyte, but they’re very different from regular succulents. They hate harsh, direct sunlight. Grow them in your living room or outdoors in the shade if you live in a fairly warm climate. Harsh direct sunlight will scorch the leaves. Indirect or filtered sunlight is best. A west/east facing window is perfect.
  2. Don’t let them dry out for long periods of time, especially in summer. They can live without water for quite a while, but if you want them to grow fast, they need water. I water mine every week in summer and every two weeks in winter. If the soil feels dry, you know it’s safe to water.
  3. Fertilize every month in spring and summer and watch the results. The vines and flowers need energy to grow. I use a regular non-brand 10-10-10 fertilizer for indoor flowering plants.
  4. So.. the flowers. The most important thing here is lots of (indirect/filtered) sunlight. If you grow yours in the middle of your living room, far from your windows, it might not flower at all. Some types of Hoya are fussy and will resist all attempts at inducing flowers while others will bloom every year even when mistreated. Lots of light, moderate fertilization, medium to high air humidity, time and a sprinkle of luck will help. Hoya bella, Hoya carnosa and Hoya Pubicalyx bloom very easily if point 1-3 is under control.
    Oh, and if your Hoya does develop peduncles and flower buds, do not move your plant! If the plant is stressed by the change in humidity and light, it will abort its flower buds. When your Hoya is done flowering, don’t remove the peduncles. Next year, it will develop flowers from those same peduncles.
  5. Propagating your Hoya is really easy, too. Take a clean knife or scissor and cut the stem just above a leaf pair, making sure the cutting has at least 2 leaves – preferably 4-6 leaves. You can propagate the cutting in moist soil or in a glass of clean water. Personally I found soil propagation more effective, especially when I use a plastic bag to keep humidity high. A healthy cutting will develop new roots in 1-3 weeks. If you water propagate, you can transfer the cutting to a pot with soil when the roots are a couple of cm. in length.
