How to take care of

Hoya Insularis?

Hoya insularis is a very finicky hoya that despite having the same care requirements, tends to be very exacting. You might have to experiment a bit to find the corrent balance for your plant.


  • Bright, diffuse light
  • Temperature range 18-25 degrees C
  • Humidity range 40-60%
  • Water when dry
  • Well-draining coarse soil
  • Fertilizing during the growing season.

Hoya Insularis Care Detail

Light Requirements:

  • Light requirements for Hoya insularis vary depending on the season and age of the plant. 
  • Younger plants should be kept in bright indirect sunlight or partial shade, while mature plants benefit from more direct sunlight but still require protection from midday sunrays. 
  • If light levels are too low, the stems become weak and leggy, while too much direct sunlight can burn the leaves. During winter months, Hoya insularis may experience dormancy where it requires less light intensity to encourage flowering in springtime again.
  • For optimal growing conditions, it is important to monitor how much light your Hoya insularis is receiving throughout the year. The best way to do this is by providing a consistent balance between indirect sunlight and shade so that it can grow without being damaged by intense sunlight rays or lack of enough light for photosynthesis. 
  • Additionally, you need to adjust lighting levels according to seasonal changes as well as its age; older plants will require more direct sunlight than younger ones. Providing adequate light ensures your plant grows into a full-grown healthy specimen with beautiful blooms!

Temperature Requirements:

  • This species of plant is native to tropical and subtropical climates, so it prefers temperatures between 18 and 24 degrees Celsius. 
  • Temperatures higher than this can cause the plant to wilt, while cooler temperatures can cause stunted growth or death of the plant.
  • It is important to avoid sudden changes in temperature; exposure to temperatures outside the recommended range can cause serious damage or even death of the plant. Thus, maintaining consistent temperatures within the recommended range is paramount for successful cultivation of this species.

Humidity Requirements:

  • Humidity requirements for hoya insularis are critical to ensure that the plant thrives in its natural environment. Indoor humidity levels should be maintained above 50%. 
  • Humidity requirements should be monitored as hoya insularis is a tropical species and has limited adaptability to low humidity conditions. Here are a few simple tips to help you keep your hoya insularis healthy:
  • Place the pot in a tray of water, allowing the water to evaporate and provide the necessary moisture for your plant.
  • Position your plant away from direct sunlight, fans or air conditioners which can cause it to dry out quickly.
  • Use a humidifier or pebble tray near your plant to increase the level of moisture in the air.

Watering Requirements:

  • Water requirements are an important consideration when growing Hoya insularis indoors. The soil should be kept moist but not wet, with plenty of drainage.
  •  Watering needs can vary depending on the season; during the warmer months, Hoya insularis requires more frequent watering than in cooler months. 
  • However, too much water can lead to root rot, so it's important to never let the soil become soggy or saturated. 
  • In order to provide optimal care for Hoya insularis plants, it is essential that their water requirements are met appropriately. To ensure this happens, check the soil by sticking your finger into it up to your knuckle - if it feels dry then it's time for watering.

Soil Requirements:

  • The optimal soil type for Hoya insularis should be well-draining with a pH between 6.0 and 7.0. 
  • A mixture of potting soil, perlite, and vermiculite works best for this species. This mixture ensures that the soil is light and airy, allowing the roots to breathe and preventing waterlogging or root rot from occurring.
  • The potting mix should also contain some organic matter such as compost or bark to ensure that the plant receives adequate nutrition.
  • When planting Hoya insularis, it is important to use a pot with drainage holes at the bottom so that excess water can escape after watering.

Fertilizing Requirements:

  • The care and maintenance of Hoya insularis is an important part of ensuring a healthy, vibrant plant. Fertilizing requirements are an especially important aspect of its care that should not be overlooked. 
  • A balanced liquid hoya fertilizer with the right NPK ratio should be applied every two weeks during the growing season, spring to summer. During the winter months, when growth slows down, fertilizing should be reduced to once a month or even less often, if desired.
  • Alternatively, slow-release granules may also be used. When using these granules, apply them in early spring and then again in late summer for best results. It is wise to avoid overfertilizing this species; too much nitrogen can cause leaf burn and yellowing of foliage.
  • When caring for Hoya insularis, organic fertilizers such as fish emulsion or compost tea are also acceptable options and can add beneficial microorganisms to the soil to promote root health. 
  • Additionally, soil amendments such as bone meal or rock phosphate can help improve fertility of the soil over time.
  •  Whatever fertilization method is chosen, it is important to keep in mind that consistent application throughout the growing season will help ensure success in cultivating this unique variety of hoya plant.
