Hoya glabra Borneo

Hoya Glabra Borneo

The Hoya glabra Borneo is a large Hoya with luxuriant green leaves. This plant comes from South East Asia, just like many other Hoyas. It is specifically from the humid mangrove forests of the island of Borneo. It is sometimes referred to as Hoya glabra Borneo because of this. This tropical species also falls under the category of fragile perennial houseplants.

This Hoya's scientific name honours a well-known plant collector by the same name, Rudolf Schlechter. 

This species has large green leaves with a crinkly surface and a somewhat spherical form. They expand to your hands' size or more. When given ideal humidity levels, Hoya glabra Borneo can put out flowers, appearing in a variety of pink and mauve tones. The centres of the tiny blossoms are a bright golden hue, with a thin off-white, star-shaped border. 

The blooms are small, measuring about 12 inches in diameter, yet each umbel has 15 to 20 flowers, creating a pink ball of tiny flowers. Hoya glabra blooms have not only a gorgeous colour, but also a delicate, sweet aroma with a hint of citrus.

Care Manual for

Hoya glabra Borneo:

The care specifications for the Hoya glabra Borneo are a bit different from a few other Hoyas, owing to its large leaf shape. They are somewhat picky where temperature and humidity requirements are concerned. If those are maintained, your Hoya glabra Borneo can potentially thrive.


  • Requires moderate care
  • Indirect, bright diffused sunlight or shade
  • Temperatures between 60 and 85 degrees Fahrenheit
  • Humidity of 60% and higher.
  • Watering only when soil is dry at 1-2 inches
  • Free draining soil
  • Low pH range

Hoya glabra Borneo Detail

Light Requirements:

  • The Hoya glabra prefers direct, strong light. Provide it with as much natural light as possible, preferably in the mornings. In low light, these plants develop more slowly, making them less likely to bloom.
  • Because of its large leaves, it needs plenty of light in order to support its numerous, large leaves in addition to growing to that size.
  • Providing the plant with enough of light means your Hoya glabra Borneo will put out blooms during the growing season. 
  • You may cultivate the plant either indoors or outdoors. If you live in temperate climates, you can grow your Hoya outside. 
  • For outdoors, you should ensure that there is partial or semi-shade.. Like other Hoyas, the glabra Borneo can suffer leaf burn due to direct light. 
  • Try to provide it with some light shade so that it can remain brilliant while shielding the plant from the sun's beams. It can only tolerate brief periods of full sun each day.
  • East or west facing rooms are best indoors. You can keep it facing south as long as you keep it away from the sun's rays or use anything to block the light from the window.

Temperature Requirements:

  • The optimal temperature range for the Hoya glabra is between 60 and 85 degrees Fahrenheit. It is a warm-weather plant that thrives in situations that range from mild to hot.
  • Due to the fact that most homes have temperatures that the plant prefers, it is relatively simple to care for indoors as a result.
  • Snow, winter, and freezing temperatures become a problem if you live in a colder area. You cannot grow your Hoya glabra outside in this care. 
  • The plant is not very tolerant to cold weather. Additionally, it struggles in conditions below 55 °F.
  • Keep it warm and comfy inside during the winter. If necessary, lay a heating mat or heat pack under the pot to maintain a warm soil temperature.

Humidity Requirements:

  • The plant benefits from humidity levels of 60% or higher. It is native to Southeast Asia, and 60–75% is the typical daily humidity range you might anticipate there.
  • The hoya species is extremely adaptive, though. Additionally, it can stand humidity levels as low as 50%. As long as the air is not too dry, it can thrive in many homes.
  • However, growth is often at its best around 60% humidity and above. Additionally, you should try to raise the humidity during the summer to boost the likelihood of the plant flowering.

Watering Requirements:

  • The Hoya glabra Borneo dislikes getting too much water. It also dislikes becoming entirely dry. Therefore, striking a watering balance should be your aim. 
  • Use a flexible watering schedule instead. To determine when to water the plant, feel the soil instead. If the soil feels moist upto 2 inches when you insert your finger in the soil, do not water your Hoya. 
  • However, it is appropriate to water if your fingertip feels dry or if all that is left is soil dust.
  • You reduce the possibility of overwatering the plant by waiting until the top layer of soil has dried before watering it again.

Soil Requirements:

  • Hoya glabra Borneo thrives in well-draining, airy, and light soil. Since the Hoya glabra Borneo stores water in its semi-succulent leaves, it needs soil thatthat does not retain much water. 
  • These plants are epiphytic; they do not really need soil for growth. They climb on trees in their natural habitat and take oxygen and nutrients from their exposed roots. Therefore, proper drainage and aeration are vital to sustain its growth. 
  • You can use the following combinations: 
  • 50-50 mix of potting soil and coco air. 
  • 1 part potting soil, ½ half part orchid mix and one part perlite
  • If you are unsure how to mix your potting soil, simply request an African Violet mix from your gardening shop.

Fertilizing Requirements:

  • Due to its large foliage, the Hoya glabra Borneo requires fertilizing, especially during the growing season. 
  • Use a balanced, water-soluble fertilizer at 50% dilution once a month during spring and summer. 
  • To support foliage growth, use a nitrogen-based fertilizer. 
  • To encourage and support blooming, use a fertilizer with an appreciable percentage of phosphorus. 
  • Over-fertilizing can damage the Hoya glabra Borneo’s roots. Therefore maintain caution while using fertilizer. Use only if you feel your plant is not growing well. 

Dormancy periods:

  • The plant enters a dormant state during the winters and does not show appreciable growth. However, the plant is healthy and alive. 
  • Do not ignore your plant during the dormancy period; maintain a reduced watering schedule that can help it survive the dormancy period and remain healthy. 
  • Maintain optimum temperatures and humidity around it. If you do not have a separate thermostat, keep your Hoya glabra Borneo in the kitchen or bathroom. These rooms remain warm, and plus it can receive much-needed warmth and humidity in the bathroom when you take a shower. 
  • If your Hoya is too large for you to take into the bathroom, you can use a humidifier and warming mats to maintain its optimum levels of temperature and humidity. You can also use a pebble tray for maintaining humidity. 
  • If you are not getting enough light during the winter months, use artificial warm light to maintain your Hoya glabra Borneo.
