Hoya Lacunosa is a plant that grows in South East Asia, which means that its natural environment are the tropics which are very humid. Now luckily for you these plants are actually very resilient to different levels of humidity and can do quite well in lower humidity however will suffer in very dry areas or if placed on top of windows.
Why not read how often to water Hoya Lacunosa!
Although they can do well with lower levels of humidity if you want to encourage optimal growth then you should try to keep them in a high humidity environment, ideally with a minimum level of 60%. Of course this isn’t always possible and your plant may not do badly if you keep it in lower levels, just that this is for optimal growth.
However, if you are willing to change the humidity levels in your home then we would definitely recommend it. One quick and easy way to do this is to buy a humidifier. There are many fantastic models available where you can set the level of humidity you want the room to be at and the machine works with a sensor to ensure that it is always kept at that level. There are some models that have a 7 day capacity tank. There are some that can alternate between cool and hot mist. Whatever you need there will be a model for you. And if you don’t want to spend a lot of money on one you can buy one with less features for much cheaper.
If you don’t fancy a humidifier then misting your plants is another fantastic option. Misting your plants once or twice a day is a great way to raise the moisture levels around your plant and will benefit your Hoya Lacunosa greatly. Plant misters can be a cheaper alternative to humidifiers but they do require you to put in more effort as you will manually need to mist your plants nearly every day to see similar benefits to a humidifier.
