Hoya Sunrise Plant Care 

Caring for Hoya Sunrise is relatively the same as for Hoya New Guinea Ghost. With proper attention to its needs, you can ensure the health and vitality of this beautiful plant. 

Here are some essential care guidelines for Hoya Sunrise:


Hoya Sunrise thrives in bright, indirect light. Place it near a window that receives filtered sunlight or provide it with bright artificial lighting.

If your window receives intense sunlight, consider using a sheer curtain or placing the plant a few feet away from the window to protect it from direct rays.

Inadequate light can result in leggy growth and less vibrant foliage, so finding the right balance is essential.


Hoya Sunrise prefers average to warm temperatures between 60°F and 80°F (15°C to 27°C). It prefers warm conditions, so avoid exposing it to cold drafts or temperatures below 60°F (15°C).

Protect the plant from drafts and sudden temperature fluctuations, especially during the winter and summer months

Sudden temperature fluctuations can stress the plant and lead to leaf damage.


Water Hoya Sunrise when the top inch (2.5 cm) of soil feels dry. It’s important to avoid overwatering, as Hoya plants are susceptible to root rot. 

Ensure that the pot has drainage holes to allow excess water to escape. During the winter months, when the plant is in a dormant phase, reduce watering frequency.


Humidity for Hoya Sunrise

Hoya Sunrise appreciates moderate humidity levels but can tolerate average household humidity. You can increase humidity in many ways:

Humidifier: Using a humidifier is an effective and convenient method to maintain consistent humidity levels around the plant.

Pebble Tray: Fill a tray or saucer with water and place pebbles or stones in it. Set the potted Hoya Sunrise on top of the pebbles, ensuring that the water doesn’t touch the pot’s bottom. It increases the humidity around the plant.

Misting: Regularly mist the leaves of the Hoya Sunrise using a spray bottle filled with room-temperature water. This helps to mimic the natural humid conditions it thrives in.

Grouping: Grouping plants together can create a microclimate of increased humidity due to the collective transpiration of the plants. Place the Hoya Sunrise near other houseplants to benefit from their combined humidity output.


The Hoya Sunrise thrives in well-draining soil that retains some moisture while allowing excess water to drain freely.

Use a well-draining potting mix for Hoya Sunrise, such as a mixture of peat moss, perlite, and orchid bark. This type of soil allows water to drain freely and prevents waterlogging.

Compost or well-rotted organic matter can be incorporated into the soil mix to enrich it with essential nutrients and promote healthy roots.

This allows the roots to breathe and promotes healthy growth.

The ideal pH range for Hoya Sunrise is slightly acidic to neutral, around 6.0 to 7.0.

Most commercial potting mixes are formulated within this pH range, but if you’re preparing your own mix, ensure it falls within the appropriate pH parameters.

Ensure that the pot you choose has drainage holes at the bottom to allow excess water to pass.

Proper drainage prevents waterlogging and the risk of root rot.


Feed Hoya Sunrise with a balanced, water-soluble fertilizer formulated for houseplants.

During the growing season (spring and summer), fertilize the plant once every two to four weeks. Reduce or stop fertilization during the dormant period in winter.


It can help to maintain a compact and bushy shape for Hoya Sunrise. 

Remove any yellowing or damaged leaves promptly to encourage new growth. Trimming back leggy vines also promotes bushier growth.

Use clean, sharp pruning shears or scissors to make clean cuts just above a leaf node. Pruning can be done throughout the year as needed. Always sanitize your pruning tools before use to prevent the spread of diseases.

Support and Training

If desired, provide a trellis or moss pole for Hoya Sunrise to climb. This allows the plant to showcase it’s trailing or climbing growth habit. Gently guide the vines to the support structure to encourage upward growth.

Repotting Hoya Sunrise

Repotting becomes necessary when your Sunrise Hoya outgrows its current pot or the soil becomes compacted. When repotting, follow these steps:

  • Choose a new pot that is one size larger than the current pot, allowing for sufficient room for root growth.
  • Gently remove the plant from its current pot, being careful not to damage the roots. If the roots are tightly packed, you can gently loosen them to encourage outward growth.
  • Place fresh soil in the new pot and create a small mound in the center. Position the Hoya Sunrise on top of the mound, spreading the roots outward.
  • Fill the remaining space with soil, ensuring that the plant is at the same level as before. Lightly press the soil around the plant to secure it.
  • Water the newly repotted Hoya Sunrise thoroughly to settle the soil and promote root establishment.

Tips: Remember to monitor the plant closely after repotting to ensure it adapts well to its new container. Adjust your watering routine as needed, and provide appropriate care based on the specific requirements of your hoya sunrise.

Hoya Sunrise Propagation

Hoya Sunrise can be propagated through stem cuttings.

  • Select a healthy stem from the parent plant that has at least two to three nodes (points where leaves emerge).
  • Using clean and sharp pruners or scissors, make a clean cut just below a node leaving one or two leaves at the top.
  • If desired, you can apply a rooting hormone to the cut end to promote root development (optional).
  • Place the cutting in a container filled with a well-draining propagation mix, such as a combination of peat moss and perlite.
  • Keep the soil consistently moist but not waterlogged and provide bright, indirect light.
  • After a few weeks, you should start to see new roots forming.
  • Once the roots are well-developed, you can transfer the cutting to a small pot with regular potting soil.

Common Leaf Issues of Hoya Sunrise

While Hoya Sunrise is generally a hardy and resilient plant, it can still encounter leaf issues from time to time. Here are some common leaf issues you may come across when caring for Hoya Sunrise:

Yellowing Leaves

It can occur due to various reasons, including overwatering, underwatering, nutrient deficiencies, or natural aging.

Assess the plant’s watering routine and adjust accordingly, ensuring the soil is neither too dry nor waterlogged.

Consider fertilizing the plant with a balanced fertilizer to provide the necessary nutrients.

If the yellowing is limited to older leaves at the bottom of the plant, it may be a natural process as new leaves emerge.

Brown Spots or Edges 

Brown spots or edges on the leaves can be caused by inconsistent watering, underwatering, or low humidity.

Check the soil moisture regularly and water the plant when the top inch (2.5 centimeters) of soil becomes slightly dry.

Increase humidity levels by misting the leaves or using a humidifier.

Avoid using water with high salt content, as it can cause leaf burn.

Leaf Curling

Leaf curling can be a response to dry air, low humidity, or inadequate watering.

Increase humidity levels around the plant by misting the leaves or placing a tray of water nearby.

Ensure the plant receives adequate watering, allowing the soil to dry slightly between waterings.

In some cases, curling leaves can also be caused by excessively high temperatures or direct sunlight, so adjust the plant’s placement accordingly.

Leaf Spotting or Discoloration

Leaf spots can occur due to fungal or bacterial infections.

Treat any visible pests with appropriate measures, such as insecticidal soap or natural predators.

For fungal or bacterial issues, consider using a fungicide or adjusting environmental conditions to discourage disease development.

Remove and dispose of severely affected leaves to prevent further spread.

Tips: Assess the plant’s conditions and adjust as needed, providing stable and suitable growing conditions.

Regularly inspecting your Hoya plant leaves can help you identify and address any issues promptly.
