Soil Mix

In general, hoya can be classified into two places where they live: Epiphytic and Terrestrial. Epiphytic means the plants live on other plants’ surfaces to thrive, Hoya Vittelina. On the other hand, terrestrial plants mean they need real soil to grow such as Hoya Verticillata.

Take an example of Hoya aff Vittelina where vining on big trees in the forest, you can hang them in a piece of woods with a handful of sphagnum moss as their ‘soil’. Sphagnum moss will likely hold water to keep your Hoya thrive. 

Meanwhile, with terrestrial hoya like Hoya Verticillata, you can mix your mixed soil. In our nursery, the common formulation is orchid bark, perlite, and houseplants soil with a ratio of 1:1:1. With this mixed, the soil is less solid and has a lot of aeration. Thus, make your hoya breath more.

Some terrestrial hoya will likely have sweet soil where alkaline is higher than regular soil. You can try to use clean crushed eggshells to mix in your soil. These eggshells also help with enhancing more calcium in your soil. 

Watering Hoya

Watering Hoya

As mentioned above, Hoya water needs could be different from each other. For Epiphytic hoya, since the sphagnum moss does not really hold the water, they tend to dry out easily. During hot days, you can water or spray your hoya more frequently.

Terrestrial hoya on other hand, you can have less watering since soil likely holds more water than but still sphagnum moss then you need to be careful to not overwater them.

Any species of Hoya you have, please be mindful while watering them. Overwatering your Hoya only harms them with root rot because Hoya roots could be sensitive when they are soaked in too wet media too much.

Besides all mentioned above, there are some general tips for taking care of Hoya that can be applied to any hoya you have.

Hoya’s basic need is a good drainage Pot. For terrestrial Hoya, drainage pots are important. When your pot doesn’t drain well, the soil tends to be soggy and it will only cause your Hoya to root rot. You don’t want it, right? Always a well-drained pot.

Always mind the distance between your Hoya. Their tendrils will tangle at each other when they get too close. Whenever the tendrils start to tangle, it will make them grow slower and harder to bloom.

Don’t cut the wooden tendril. When your Hoya is about to bloom, they will grow wooden tendrils in brown color. It is different from new young tendrils. This wooden tendril will be a place to bloom the flowers.

Limp hoya is not okay. You know your hoya is not okay when their sturdy leaf starts to limp and wilt gradually. It can need more water or too much sun. Always pay attention to what they need.

Taking care of Hoya is not as hard as we might think. Always give them attention to see what they need, especially when they just arrived and need to acclimate to a new environment.
