Introduction

The hoya cinnamomifolia grow naturally in Java, and is known for its large (for a hoya) dark green leaves. It can be a bit fussy to be honest, you may need to be patient with it! The blooms are really impressive luminous yellow and dark purple.

Hoya Cinnamomifolia Light Needs

Give your hoya cinnamomifolia bright indirect sunlight, it will encourage it to grow and give it the energy it needs to bloom. Avoid direct sun if you can.

How Often To Water

Water it only when totally dry, they are epiphytic and grow in bark in the wild, not in soil, so hey hate to sit in wet soil. Check it once a week and water if totally dry.

Tip: make sure you do not water the plant until the soil is completely dry all the way down, as the biggest killer of hoyas is root rot. If in doubt, underwater it!

Hoya Cinnamomifolia Fertilizer

Feed it a well diluted balanced feed once a month in spring and summer to encourage growth and flowering.

Soil

Remember that hoyas do not grow in soil in the wild, so use a cactus compost mixed with the same volume of orchid mix is good mix. For more on hoya soil (what to buy and how to make your own) see our guide here: Hoya Soil.

When To Repot

Hoyas do not mind their rots getting bit crowded, but check them in spring just to be sure and plant them up a pot size if needed, then the will have space to grow over the coming warmer months.

Hoya Cinnamomifolia Humidity

50% or more is best, they will do well a bit lower, but thrive if given 50% or more humidity.

Temperature

They will do well in most homes and do not mind getting a bit cold in winter, but aim for 15-28°C (59-82°F). Don’t let them get too much lower than 12°C (54°C) at night for long periods of time.

How To Propagate Hoya Cinnamomifolia

Hoya Cinnamomifolia can be propagated by taking a cutting that has as least two nodes and a few leaves. You want a node with leaves above the soil/water and one node below with no leaves that will root. Take the leaves from the bottom node, then leave it for a few hours until the wounds heal over, as open wounds can rot more easily.

Then you can put the cutting in a jar of filtered tap water. It should root in one or two months then you can move them to a good hoya soil mix.
