Hoya Sunrise does great with 6 hours of bright, indirect lights with 17-25 °C temperature and high humidity (60-80%). It also requires weekly watering in well-draining soil with 6.5- 7.5 pH, monthly fertilizer and regular pruning and once every 2-3 years repotting. 

This is only a basic need; if you want to grasp all the requirements and growth features of this special Hoya, let this piece guide you!

1. Sunlight & Temperature

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 with a temperature of 17°C-25°C a day.

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.

Place the plants under the grow light if there is low light.

Also, 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.  

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 winter, remove your Hoyas from chilly windows and place them indoors. Avoid placing your plant near fans, vents, air conditioners, and heaters.

2. Water & Humidity

Make sure to water your hoyas once in 2 weeks in the wintertime and no more. As for summer, twice a week would be ideal.

But when you observe blooms developing on your Hoyas, reduce the amount of water. 

Check to see if the water in the pot is draining or if the topsoil is 2-3 inches dried.  

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.

Along with water, ensure the humidity is between 60% and 80%.

A plant meter can help learn the exact humidity level; if the humidity level is low, consider using a humidifier.

Extremely arid regions can cause brown leaf tips and wilt due to the dry condition.

For optimum performance, mist frequently, but avoid making it too wet or use a pebble tray to trap moisture around the pot. Also, grouping the plants can be another alternative. 

3. Proper Soil Mix & Fertilization

Hoyas always prefer lightweight and well-draining soil mix.

Mixing 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.

It can grow appropriately in neutral soil with a pH of 6.5 – 7.5.

Additionally, the plant can flourish with a scoop of crushed limestone and a few bunches of horticultural charcoal with moderate fertilization.

A well-balanced water-soluble NPK fertilizer is recommended in the ratio 2:1:2 or 3:1:2 once in three months. But with natural fertilizers and compost, once a month seems perfect.

Underfertilization Signs:  The lower or more seasoned leaves will usually become yellow or pale, looking green and dry, causing stunt growth. Some might become tarnished/orange and frequently twisted and mutilated. 

Overfertilization Signs: Brownish and dehydrated leaves are a sign of over-fertilization.

Ensure you fertilize your hoyas in spring or summertime but not during the cold winters.

4. Potting and Repotting 

Hoya Sunrise loves being root-bound.

Once your Hoya doubles its size, you know it’s time to repot your plant, i.e., most likely to be in two or three years. 

Terra cotta pots can be a superior choice for drainage facilities.

Pot Sizes for Hoya Sunrise: 3.5-4 inch pot for Small| 5-6 inch for Medium, 7-8 inch for Large

An actively growing spring and summer season is best for Potting and Repotting.

5. Regular Pruning

The most frequent Hoya-lovers are aphids, mealybugs, scale, and fungus gnats. Besides, Hoya Sunrise is also prone to Botrytis Blight and Sooty Mold. 

You can apply fungicides comprising chlorothalonil, sulfur, copper, captan, mancozeb, and thiophanate methyl. And ultimately, you need to prune the Hoya Sunrise. 

Large, unsightly tendrils can appear on the 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. 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.

Hoya Sunrise: All About Growth Habits

Hoya plants prefer hanging or ascending a frame and are great for suspending arrangements and pots. With that said, Hoya Sunrise develops trailing and vining growth habits. 

And if provided with good care, Hoya Sunrise can live for around 3o years with 9 feet X 1-2 feet mature size. 

They produce dark green leaves in a teardrop shape and red veins that grow in spring and summer. 

It may take for Hoya plants to flower, and Hoya Sunrise yields small cream-yellow blooms with sweet scent year around in in the actively growing seasons. 

The flowers may shade pink if grown in sunlight and white in the shade. 

Toxicity of Hoya Sunrise

Generally, Hoya plants are nontoxic to pets, including cats, dogs and horses. 

With that said, Hoya Sunrise is not poisonous, but it can make your furry companion or kid puke if ingested.

Hence, keep them out of range, just in case.

If anything happens unnatural, here are a few emergency hotlines!

Propagation Methods for Hoya Sunrise 

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.

1. Propagation Through Leaf Cuttings

You must expect to wait six weeks for a root to form from the leaflets in the soil.

  • 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.

2. Propagate Through Stem Cuttings

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.

If you mistakenly pour a lot of water, take the cuttings under the sunlight.

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.

3. 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.

  • Fill a fresh pot halfway with soil and set it aside for the 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.
