Introduction

The Hoya Sunrise is a hybrid of the hoya obscura and hoya lacunosa. We cover all you need to know about this beautiful hoya…

Light Needs

Medium to bright indirect sunlight is ideal. You want it to be towards the higher end when blooming, or before blooming, to encourage those flowers.

How Often to Water

Check the soil once a week and only water them if it is totally dry all the way down. Hoya must not be too wet as they can get root rot very easily.

Fertilizer

Use a well diluted balanced feed in the summer to encourage growth.

Soil

Hoya sunrise needs a really well draining epiphytic mix, something like orchid bark, perlite and cactus soil in equal parts.

For more on hoya soil (what to buy and how to make your own) 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.

When To Repot

Check the roots in spring time and pot them up a size if needed. They can be slow growing so it may well not need it, but give them space to grow if they are getting crowded.

Humidity

Aim for a humidity of 60% to get the best out of them, but they will be tolerant of much lower levels.

Temperature

15-25°C (59-77°F) is ideal. They are ok to go a bit lower than that at night too.

How To Propagate A Hoya Sunrise

Take stem cuttings (with 3 or 4 nodes) and water propagate them to get them started, with one or two nodes under the water. Take the leaves off the underwater nodes, but keep them on the nodes above the water. Keep them in a bright spot but out of direct sun. Once the cutting starts to root over the next few weeks you can pot it up into a hoya mix.

Is Sun Stress Bad For A Hoya?

As long as you keep an eye on the plant and avoid sunburn, then sun stressing is ok. Keep an eye on water levels too as the plant can dry out quickly. It can go wrong quickly and you send up with scorched plant! So be careful.

Hoya Sunrise Flower Smell

The hoya sunrise scent is a a sweat smell, almost honey-like.

Is It Toxic To Cats?

The good news is hoyas are non-toxic to cats and dogs.

How Fast Does Hoya Sunrise Grow?

Hoya are relatively slow growing plants. They can grow steadily and you should see new growth, but they do not grow fast like monsteras or pothos.

Hoya Sunrise Vs Rebecca Are They The Same?

They are similar shapes and size, as they are both hybrids of the hoya lacunosa and hoya obscura. The rebecca is a hybrid of the lacunosa langkawi island (and obscura), but the sunrise is a hybrid of the lacunosa pallidiflora (and obscura).

Hoya Sunrise Vs Obscura

The hoya sunrise is a hybrid of the obscura and the lacunosa so they have many similarities, but the sunrise has a deep red, maroon color to it, especially when sun stressed.
