Hoya Sunrise (Complete Guide for Gardeners)
Countless plant lovers claim that all Hoyas are the simplest houseplants to maintain, and the same goes with Hoya Sunrise!
Because they can endure indifference, they make great low-maintenance houseplants.
Hoya Sunrise is reasonably easy to maintain as long as it is kept in a sunny location and appropriately watered.
In its native surroundings, this variety, like so many other Hoyas, is epiphytic, meaning it is air vegetation with bristly succulent leaflets.
|Sunlight and Location||Plenty of warm, indirect light is preferable.|
|Ideal Temperature||Temperatures between 17°C to 25°C are ideal.|
|Watering||Moderate water requirements.|
|Humidity||They thrive in increased humidity.|
|Fertilization||Medium feeders that require moderate fertilization.|
|Pruning||Once to twice a year to encourage new growth.|
|Soil Mix||Light and well-draining soil is preferred.|
|Pests||Aphids, mealybugs, scale, and spider mites are Hoya lover.
|Diseases||Prone to fungal infections.|
|Re-pot||Once in every two to three years.|
|Propagation||Stem cutting work the best.|
1. Sunlight and Location
If you want your Hoyas to give you plenty of vibrant and attractive leaves, place them beside a bright window that receives sun all day long.
Bright, Dappled light is preferable for Hoya Sunrise for at least six hours a day.
The plant can indeed improve under artificial light if it is not possible to fulfill the light requirements naturally.
South-facing windows would be flattering to your Hoyas. However, place it less than 3ft from the window for maximum potential growth.
Also, make sure to place your Hoya Sunrise in such a way that its stem can grow downward.
It can tolerate lower light levels, although you may detect darkening or puttering of the foliage. It will also not show the beautiful bright red veins.
2. Watering Requirement
Hoyas do not require plenty of water. However, if you see that the soil has dried out, it is the perfect time to water your Hoya Sunrise.
Make sure to water your hoyas once in 2 weeks in the wintertime and no more. As for summers, twice a week would be ideal.
You should also make sure to water your plants first thing in the morning.
In doing so, moisture will be supplied throughout sunshine hours, ensuring that the soil is completely dry at night.
Also, check to see if the water in the pot is draining. Allowing water to collect in the plant pot base will induce root rot.
When it concerns watering tendencies, Hoya Sunrise, in particular, demands the exact combination of not too much and not too little.
But when you observe blooms developing on your Hoyas, reduce the amount of water.
Underwatered Hoya Sunrise: The tendrils will start to look crispy at the tips and eventually die. The foliage will lose its moisture and start limping.
Overwatered Hoya Sunrise: The roots and leaves of a Hoya that has received too much water will appear soft and mushy and will not reestablish succulence after soaking in water.
3. Ideal Temperature
Temperatures between 17°C to 25°C are ideal for Hoya Sunrise.
The leaves appearing brownish and dehydrated is a clear indicator of excessive heat.
Regular light misting can work as temperature control for your plant during summer. Also, make sure the Sunlight is indirect.
In case of increasing temperature beyond the tolerance limit of the plant, it would be better to move your plant inside.
Using a sheer curtain can act as a shade while keeping it in a brightly lit place.
Avoid lowering the temperature below 10°C, which may result in cold damage leading to stunting.
In winters, remove your Hoyas from chilly windows and place them indoors.
Avoid placing your plant near fans, vents, air conditioners, and heaters.
4. Ideal Humidity
Hoya Sunrise can take average humidity, but it thrives in increased humidity.
They prefer humidity between 60% to 80%.
A plant meter can be helpful to know the exact humidity level.
If the humidity level is low, consider using a Humidifier.
For optimum performance, mist frequently, but avoid making it too wet or use a pebble tray to trap moisture around the pot.
Extremely arid regions can cause brown leaf tips and wilt due to the dry condition.
5. Proper Soil Mix
A plant mix containing over 50 percent orchid peel, charcoal, coco peat, or sphagnum material with the remaining 50 percent sterilized horticultural manure and perlite works great for Hoya Sunrise.
They always prefer lightweight and well-draining soil mix. It can grow appropriately in neutral soil of pH range 6.5 – 7.5.
Additionally, the plant should flourish with a scoop of crushed limestone and a few bunches of horticultural charcoal.

6. Proper Fertilization
Hoya Sunrise are medium feeders that require moderate fertilization but at a reduced rate. Plant food is essential for healthy growth and maintenance.
A well-balanced water-soluble NPK fertilizer is recommended in the ratio 2:1:2 or 3:1:2.
You can ideally feed your Hoyas with chemical fertilizers once in three months. But with natural fertilizers and compost, once a month seems perfect.
Some of the fertilizers that can be used for your Hoya are:
- Sun Bulb Company 8305 Better Gro Orchid Plus Bloom Booster Fertilizer, 16-Ounce
Ensure you fertilize your hoyas in spring or summertime but not during the cold winters.
Underfertilization Signs: Slow or stunted growth can signify that your plant lacks proper plant food.
The lower or more seasoned leaves will usually become yellow or pale, wiped out looking green and dry. Some might become tarnish/orange and frequently twisted and mutilated.
Overfertilization Signs: Brownish and dehydrated leaves are a sign of over-fertilization.
7. Growth Habits
Hoya Sunrise belongs to the Apocynaceae family and grows as an epiphyte.
They prefer hanging or ascending a frame and are great for suspending arrangements and pots.
8. Regular Pruning
Large, unsightly tendrils can appear on Hoya Sunrise plants occasionally.
Blooming stems come from empty plant areas, so do not trim them.
Enable wilting blossoms to drop off the plant at their own pace as well. Fresh blossoms develop on the stems of old blooms, so don’t pluck the flowers.
If trimming is required, use floral snips, the best time is the spring or early summer, starting with the main stem to stimulate the emergence of numerous side stems and, subsequently, blossoms.
Prune weak vines once a year to ensure the healthy appearance of your Hoya Sunrise.
9. Common Pests in Hoya Sunrise
Even though all Hoyas, notably Hoya Sunrise, are pest-resistant, they are susceptible to several bugs.
The most frequent hoya-lovers are aphids, mealybugs, scale, and Fungus gnats!
- Aphids: Aphids appear to enjoy all milkweed species, including Hoyas, and they are typically easy to get rid of by merely spraying them off with tap water.
- Mealybugs: Mealybugs love to lurk in the cracks and crevices of the Hoya Sunrise. Still, they are pretty straightforward to eradicate in tiny groups by dabbing off any mealybugs with a q-tip coated in rubbing alcohol.
- Scales: Scale is particularly aggravating because its scale-like shell protects them from pesticide sprays. It is better to hand clean any visible scale bugs before spraying with a pesticide.
- Fungus gnats: They lay eggs in the preparing blend. The eggs incubate into tiny, practically tiny worms that feed on the peat greenery and frequently on the underlying foundations of your plants.
Make sure you invest in a good insecticide to keep your hoyas healthy and bug-free. Or, get yourself an all-rounder neem oil.
10. Common Diseases
Hoya Sunrise can be infected with two particular fungal infections that harm the leaves and the rest of the plant.
Carefully check the plant occasionally as this houseplant’s waxy leaves can block withering, allowing root and stem rot signs to go undetected until the ailment has developed.
Large, gray-colored spots appear in the middle or along the edges of the affected plant, indicating botrytis blight.
It is mainly caused by a fungus named Botrytis cinerea that attacks the plant in the presence of high humidity.
The gray ascospores can sometimes be seen with the help of a magnifying lens.
The foliage gets squishy and crumbles as the infection develops. Brown patches on branches, blossoms, and foliage are also possible.
Fading, brown, and black stem tumors flaky or squishy, and black or gray dried or soggy roots are all common rot indicators.
Another fungal pathogen that emerges as a black development on the leaves and stem is called sooty mold.
The fungus thrives when honeydew is secreted on the leaves and stems by aphids, mealybugs, and other nectar-sucking parasites.
But don’t worry, Botrytis blight and other infections in Hoya Sunrise can be controlled by fungicides comprising chlorothalonil, sulfur, copper, captan, mancozeb, and thiophanate methyl.
11. Potting and Repotting Hoya Sunrise
Hoya Sunrise develops gradually and outshines in pots, and it doesn’t need to be replanted often. It loves being root-bound.
If the plant does not develop or blossom, it is preferable to transplant it into a new pot with a fresh potting mix to provide better nutrition.
Once your Hoya doubles its size, you know it’s the time to repot your plant, i.e., most likely to be in two or three years.
Good drainage is the basic requirement while choosing a pot for Hoya Sunrise.
Other choices are possible, but I prefer Terra cotta pots because of their superior drainage.
An actively growing spring and summer season is best for Potting and Repotting.
12. Hoya Sunrise Propagation
The optimal time to propagate a Hoya Sunrise is when the plant develops strongly during the spring or summer.
Leaf clippings, stem clippings, layering, and seed propagation are the most frequent ways of propagating Hoya Sunrise.
Leaf and stem clippings are the finest approaches to reproducing Hoyas because they are inexpensive and straightforward.
Propagation Through Seeds
Starting Hoya Sunrise from seed is the cheapest and the most time-consuming way of propagation.
You can buy seeds at your local gardening store or use seed pods from species you already have.
The plant will take a very long time to reach full maturation, but it is worthwhile to wait if you have the endurance.
When planting Hoya seeds, be mindful that they have enough space to develop.
To maintain the Hoyas seeds and seedlings intact and thriving, leave the soil moist at all times.
Also, make sure to ensure that the temperature is around 22°C.
The seeds should be covered with a thin layer of growing medium. You should repot the saplings once they have developed leaves on their stems.

Propagation Through Leaf Cuttings
Leaf cuttings are a procedure that takes plenty of dedication and persistence because it is among the most challenging ways to propagate your Hoya Sunrise.
You must expect to wait six weeks for a root to form from the leaflets in the soil.
Step by Step Guide
- Place at least four to seven leaves in the soil, slightly covering the ends to allow roots to grow.
- Allow sufficient space between the foliage in the pot for the roots to expand as they develop.
- The leaves should be seated at a 45-degree angle to permit maturation.
- Consider using a hormone that promotes root development if you wish to accelerate this tough replication technique.
Propagate Through Stem Cuttings
This method might be time-consuming, but it is the best and easiest method for multiplying your Hoya.
Step by Step Guide
- Removing the basal leaves from the stalk.
- The lower part of the stalk should be buried in moist soil once chopped off the parent plant.
- When planting the stem clipping, the substrate should be somewhat damp.
- Provide only a tiny amount of water to prevent rotting.
- Your plant will have new roots within a month, as long as you do not overwater it.
- Using a spray bottle to water them, after all, is a fantastic way.
This method can also be performed in a water medium, as well as mentioned below:
- Set the stem clipping in a glass jar, leaving the leaflets much above the water surface.
- When the water turns cloudy, replenish it with new water.
- Transplant the cutting in a pot loaded with a well-draining potting blend or orchid mix once it has taken root.
Propagate Through Layering Method
Although the plant’s stem is used in this technique, the branch of the parent plant is still attached to the new propagated stem.
Step by Step Guide
- Fill a fresh pot halfway with soil and set it aside for new Hoya to develop.
- The soil should be lightweight and nutrient-rich.
- Place one of the parent Hoya’s stems in the new pot you have prepped for the baby Hoya to thrive.
- Using floral hooks, fasten the stem from the mother plant to the dirt in the new pot.
- Once they develop, the baby roots appear directly on top of the fresh soil, so you won’t have to dig to see them.
- Maintain a slight moisture level in the soil.
And there you go! You just managed to have your Baby Hoya Sunrise.
13. Toxicity of the Plant
Hoya Sunshine is not poisonous, but it can make your furry companion or kid puke if ingested.
Hence, keep them out of range just in case.
Additional Tips to Keep Hoya Sunrise Problem-Free
- When hydrating your Hoya Sunrise, remember to consider the season. During the spring and summer growth periods, Hoya requires extra water.
- If you want your Hoya Sunrise to climb up the fence or other structure, you can train them to do so by binding them with ropes.
- Attempt not to move your Hoya Sunrise once you have found the perfect location for it. You will know when your plants love the spot.
- Immerse the pot with the plant in a bucket of water before repotting to soften the soil and roots, making it easier to remove and less likely to cause injury.
- Insects and bugs get attracted to the plant since the blossoms of Hoya Sunrise produce savory and sweet sap. Hence, place a few citrus peels on the potting soil to keep them at bay.
