Hoya Macgillivrayi Plant Care Basics

Hoya Macgillivrayi Plant

The Hoya macgillivrayi should be given appropriate care. The gardeners should be fully aware of how to take care of the plant. Complete knowledge on the Hoya macgillivrayi care guides the gardeners on providing the plant is in an excellent growing condition.

This would allow the plant to grow healthy while manifesting its full beauty. Giving the right Hoya macgillivrayi care will be helpful for the plant’s growth, even it was planted indoors. The following are the care tips on how to take care of the Hoya macgillivrayi properly.

Soil Requirement

The soil requirement of the macgillivrayi hoya is a well-draining and well-aerated soil type. The soil required by the plant is not poor-draining soil or soil that has no drainage holes. The soil should be on a pH level of slightly acidic to neutral.

The soil can be mixed with organic materials such as peat moss and perlite- a good soil or potting medium for the plant. The plant can also be planted on decorative pots with holes for the water to drain quickly. A good example of a decorative pot suitable for the plant will be the hanging basket.

The soil requirement of the plant should not be too loose or not too dense. The roots should not be root-bound nor getting wet feet (root rot). Rootbound and root rot are problems that we should be preventing as the plant grows.

Keep the soil moist to prevent infestation or bacterial infection that will harm or disrupt the healthy growth of the plant.

Watering needs

The water requirement of the macgillivrayi hoya is a medium amount of water every two to three days, depending on the amount of moisture within the soil. The plant should have a watering schedule so it would not have any complications. The soil of the plant should be mild to moderately wet.

Be sure to water it once again if the soil appears to dry. When watering the plant, lukewarm water is a good choice for the plant. During the spring and summer seasons, watering the plant should be done frequently.

On the other hand, watering the plant should be done once or twice. In addition to that, do not overwater nor underwater the plant. Give the right amount of water the plant needs.

The humid needed by the plant should be consistent to maintain the optimal condition of the plant.

Lighting Requirement

The lighting requirement of the macgillivrayi hoya should be a bright indirect light. The bright indirect light is sufficient for the plant to be energized. Do not expose the macgillivrayi to the full sun to prevent scorching or other sun-related complications.

plant lighting requirementAlso, it is not also ideal to place the plant where it could receive insufficient sunlight. Insufficient sunlight stunts the growth of the macgillivrayi. When treated as an indoor plant, you can install a lighting source inside such as the artificial growing lights. However, this is only recommended for the gardeners who did not grow macgillivrayi in tropical places.

Temperature & Humidity Requirement

The temperature requirement of the Hoya macgillivrayi is the same as that of the tropical temperature. It is known to be a tropical plant. Meaning that it could only best thrive and tolerate conditions where the temperature is 15-30 degrees C or 59-86 degrees F.

These recommended temperatures are enough for the plant to survive and thrive well in the area where it was planted. The below and above temperatures can give complications and stress to the vine. However, the difficulties are only a minor consequence of the Hoya macgillivrayi care.

If the temperature goes too high, consider placing the vine in a temporary place where it could get its warm temperature. The vine is best to be placed outdoors during the summer and spring seasons. On the other hand, the vine is best placed indoors during the winter and fall seasons.

However, it would help if you were extra watchful every season as a sudden increase or decrease in temperature could give you a hint when is the right time to place the vine away from its permanent place.

The humidity requirement of the macgillivrayi hoya is very high. The very high humidity is what all the tropical plants needed the most. The higher the humidity level, the higher the optimal conditions you are giving on the plant.

High humidity encourages the plant to grow well and to thrive easily, making it easier for propagation for the next year or two. When planted in a place with a medium level of humidity, the plant can still survive and thrive. However, there will be an enormous difference compared to the tropical plants that grow well with a higher humidity level.

Also, the low humidity level is not suitable for the optimal condition needed for the plant to survive and thrive. To ensure a consistent and higher humidity level, you can use any available techniques and equipment present in your home or buy in the nearest garden store. You may use a humidifier, a container with pebble filled with water, mist, and other techniques to increase the humidity level required for the plant.

It is important to remember that the bathroom and living room have a consistent, higher humidity level that allows the plant to thrive well and a natural décor for the home.

Fertilizer Requirement

The fertilizer requirement of the slow-release fertilizer is slow-release fertilizer. The said fertilizer can help the plant grow faster, complete its required nutrition, and solve its vitamin deficiency. The fertilizer may take time for the plant to absorb its nutrients fully.

I highly prefer organic fertilizers for the macgillivrayi hoya care because the aforementioned fertilizer has no adverse effects on the plant. In addition to that, organic fertilizers encourage the soil mix or potting mix to be healthy and rich in nutrients.

plant organic fertilizerSummer and spring seasons are the preferable seasons where you could give apply fertilizer for the plant. These seasons are also favorable for the plant as the plant survives and thrives easily in these seasons. At the same time, these seasons are the best propagating seasons.

During fall and winter, you must not give or minimally give the plant fertilizer. These seasons, the vine usually sleeps or on dormant. Excessive fertilizer application to the vine can stick the salt or any chemicals that poison the plant.

How do we propagate our Hoya macgillivrayi

Hoya macgillivrayi is a fast-growing root climber species and twiner featuring thick, oval, pointed leaves that are light green and alternate on the twining branches.

  1. Begin by cleaning and disinfecting all of your gardening instruments. Disease and infection for your future plant will be less likely as a result of this.
  2. Next, cut off 2 to 3 vines from a non-flowering stem from the macgillivrayi plant.
  3. Choose one of the vines to work with. Select one that has two or more nodes on the lower end if possible.
  4. Next, fill a container halfway with your potting soil mix. Cover with plastic wrap.
  5. In the soil mix, plant the vines.
  6. This mixture can be supplemented with rooting powder, which promotes growth.

Growth Zone

The macgillivrayi is a fast-growing plant that can grow up to 25 cm long. This natural climber and the succulent plant are native to Australia. Its thick stems should be given a standing pole so the plant could not climb undesirably on the walls.

In its native home, the plant has been treated as a vine plant or a house plant. When taken care of properly, the flowers can bloom really well.

Know when to repot your hoya

The Hoya macgillivrayi root develops slowly compared to the plant’s green above-ground half. Thus it doesn’t need to be transplanted as frequently. You may repot your Hoya MacGillivrayi every two or three years.

They don’t mind having their roots constrained, and they’ll flower more profusely than those soaring in a big pot.

Pro tip: It’s ideal to use a terracotta pot that’s a few inches bigger than the previous one. When it comes to repotting, terracotta pots are ideal.

Pruning our Hoya macgillivrayi

Pruning Hoya macgillivrayi entails removing sick, wilted, and damaged leaves and branches to keep the plant looking nice and tidy. You can also prune any shoots that are excessively long to keep the plant at the proper size.

 Pro tip: Hoyas have twining stems and are natural climbers. If you give a ladder or framework, your Hoya macgillivrayi can reach a height of 3 meters. Bamboo hoops are commonly used to support the vine by many gardeners.

Hoya Macgillivrayi Diseases & Pests


Botrytis blight is a fungus that provokes leaves to turn grey. Because moisture levels are highest in the middle leaves, they are more commonly affected. The sickness is more common during the cold, darker months of the year.

Controlling via inspection and maintaining proper hygiene is the best defense. Remove any fading or blighted flowers, foliage, or the entire plants as soon as possible.

Root rot. The signs of this disease in hoyas can go undiscovered for a long time. The roots will eventually become gray to black and can be mushy or dry. Even when the roots die, the waxy coating on the hoya plant can prevent the wilting of the plant’s leaves.

Reduced watering of affected plants is the best way to combat this disease.


Aphids have flexible bodies. The oleander aphid is the most common aphid seen on wax plants. Essential aphid insecticides can be bought at your local garden center and are relatively easy to control.

Fungus gnats are tiny black insects that live on the top of the soil or leaves. Their larvae reside in the ground and devour the plant’s roots, causing damage. Once the gnats have been identified, soil soaking and insecticide spray on the soil surface successfully control the larvae.

Mites are so microscopic that they can go undetected until they release significant damage to the plants. New leaves cupping downward, puckering, and stunted growth are the first signs. The most crucial aspect of insect management is thorough pesticide coverage.
