Hoya Serpens Light Needs
Bright indirect sunlight is best, especially to encourage blooming. Medium indirect sun is ok too. Do not give them direct sun.
Check the soil each week but only water it if it is almost dry all the way down. They don’t ant to totally dry out as their small leaves can suffer if dried out, but you must not over water a hoya.
You can use a balanced feed every 2 or 3 weeks in the summer to encourage growth. Always over dilute your fertilizer rather than under to avoid fertilizer burn.
Hoya Serpens Soil
They need a chunky really well draining mix of something like orchid bark, perlite and cactus compost. They grow in tree back in the wild, not on the floor, so we soil will give them root rot easily.
For more on hoya soil see our guide here: Hoya Soil.
Tip: make sure you give them a soil mix suitable for epiphytes that has plenty of orchid bark, as they hate to sit in heavy wet soil and will get root rot easily. Remember that they grow on tree bark in the wild and not in soil. For more info see our guide: Hoya Soil.
Check the plant yearly to see if the roots are crowded, give them a bigger pot if they are getting root bound, so they have the best chance of growing well, also crowded roots can lead to root rot.
60% or more is ideal to get them to thrive and grow their best. They will be fine in less though.
15-25°C (59-77°F) is a good range in the daytime, and 0°C (32°F) as a minimum at night. They are better at the lower end of household temperatures.
Tip: To give it the best chance of blooming, aim for a temperature range of 20°C (68°F) – 22°C (72°F) as optimal in the day, and give it 60% humidity.
How to Propagate Serpens
Take stem cuttings with a couple of leaves and a node and root them in a sphagnum moss (you can use soil instead if you like). Keep it moist and humid and well lit and it should root in a month or so. You can put a bag over it to up the humidity, but make sure some air can get in and out or you could get fungal issues.
