Tips for nurturing your Hoya Pubicalyx
Light
The Hoya Pubicalyx prefers bright light but keep it away from direct sunlight as it will scorch the leaves. If your plant looks a bit lacklustre, this might be a sign that it needs more light.
Temperature
Aim to keep the temperature between 21-30°C for your Hoya Pubicalyx. It should not be exposed to draughts or temperatures lower than 12°C.
Soil Type and Drainage
The plant likes a mixture of regular potting soil, perlite or vermiculite, and bark or coir fibre – all the better to ensure it has sufficient drainage.
Humidity
A humidity level of 60% and above will ensure the Hoya Pubicalyx stays in tip-top condition.
Watering
This species is surprisingly tolerant of dryness, and to prevent rot, it’s better to let the plant’s soil get dry before watering. The top of the soil should be dried out in between waterings.
Toxicity
The Hoya Pubicalyx is toxic to cats and dogs, so make sure to keep it out of the reach of any furry companions.
Fertiliser
Feed your Hoya Pubicalyx a balanced nitrogen-rich fertiliser during the growing season (spring and summer) with a half-strength dose.
Troubleshooting pests, diseases and common problems
Diseases and pests can be expected in houseplants. If you notice any infestations or signs of rust, root rot, or leaf spot, treat the plant with an appropriate fungicide and pesticide.
Propagation
Propagating a Hoya Pubicalyx isn’t tricky and is a great way to increase your collection of this stunning houseplant. To start new plants, layering is the preferred method. Strip a leaf off the plant, lay it in your soil mix, ensure it’s in contact with the soil, and water it regularly. Another method is to use stem cuttings; pick a piece of stem at least 10cm long and place it in a pot with fresh potting soil. Keep the soil lightly moist to encourage good root growth.
Final Thoughts
The Hoya Pubicalyx is a beautiful, unique houseplant, perfect for brightening any living space. If you can provide the right conditions, you can enjoy its cascading blooms for many years to come – a truly rare and memorable addition to your home.
