Hoya Care Tips

Watering

Be sure to water your Hoya thoroughly, so the entire soil becomes wet. They like to dry out more than most plants, so only water them again once the soil is thoroughly dry. If they do not dry out between waterings, they will rot quite easily.

Soil

Hoyas will appreciate a lightweight and very airy potting mix. A mixture of substrate, perlite and bark, such as it can also be found in our Aroid Potting Mix, will work great for most Hoyas. Epiphytic Hoyas in particular will also do well in spaghnum moss.

Hoyas can also be grown in semi-hydro substrates, such as Leca or PON or our Alocasia Mix, since they are particularly aerate.

Light

The more succulent varieties with fleshy leaves, such as Hoya Kerrii or Hoya Calistophylla, can withstand full sun, so they will do great in a South-facing window or right under a small grow light. Meanwhile, thinner-leaved Hoyas, such as Hoya Linearis or Hoya Krohniana, will appreciate medium to bright indirect light.

Certain Hoya varieties might begin to redden their leaves due to sun stress, such as Hoya Wayetii Tricolor, for instance. This can be beautiful, but  you have to be careful not to overdo it light-wise or it will fully burn the plant and permanently damage the chlorophyll in the leaves in the process.

Humidity

Most Hoyas will do great in moderate humidity of 40-60%. Especially the more thick-leaved Hoya are not too finicky in terms of humidity, but most will thrive and grow faster if given a bit more.

Some of the thinner-leaved varieties might require higher humidity of 60-80% to thrive. They will do especially well in a greenhouse or terrarium environment.

Repotting

Hoyas like to be rootbound, so we recommend that you do not repot your Hoya all too often. Refreshing their substrate every two to three years in order to give them better, nutrient-retaining soil is enough. If they are very rootbound, you can give them a bigger pot when you refresh the substrate.

Flowering

Hoyas won’t flower unless it is given the right care and conditions. Light is the most important factor in getting your Hoya to bloom. It will need a location with bright, indirect light, sheltered from direct sun rays. Fertilising your Hoya regularly may encourage the plant to produce flower buds as well.

Toxicity

Hoyas are NOT toxic to humans or animals when ingested.
