Hoya Pubicalyx Hanging Basket

Hoya pubicalyx, also known as the “Royal Hoya,” is a popular and relatively easy-to-care-for flowering vine with stunning, fragrant star-shaped flowers and waxy, dark green leaves. It’s a great addition to your collection if you want a plant that’s both visually appealing and low-maintenance.

1. Light Requirements

Ideal Light: Hoya pubicalyx thrives in bright, indirect light. It will grow best when placed near a window with filtered sunlight.
Tolerates Low Light: While it can tolerate lower light conditions, the plant may grow more slowly and produce fewer flowers.
Avoid Direct Sunlight: Too much direct sun can scorch the leaves, causing brown spots or sunburned edges.

2. Watering

Watering Frequency: Water when the top 1-2 inches of soil are dry. Hoya pubicalyx is somewhat drought-tolerant, so it’s better to underwater than overwater.
How to Water: Ensure that the pot has good drainage to prevent water from collecting at the bottom, as this can lead to root rot.
Winter Care: Reduce watering in the winter months when the plant is not actively growing. Overwatering during this period can be harmful.

3. Temperature and Humidity

Temperature Range: Hoya pubicalyx prefers temperatures between 60°F to 85°F (15°C to 29°C). Avoid placing the plant in areas with temperatures below 50°F (10°C), as it can cause damage.
Humidity: This plant enjoys moderate to high humidity but can tolerate average indoor humidity levels. You can increase humidity by misting the leaves, placing the plant on a humidity tray, or using a humidifier.
Tropical Plant: As a tropical plant, Hoya pubicalyx thrives in warm, humid conditions, so try to keep it in an environment that mimics its native habitat.

4. Soil and Potting

Soil Type: Hoya pubicalyx prefers a well-draining, slightly acidic soil mix. A cactus or succulent mix works well, or you can mix perlite or orchid bark into regular potting soil to improve drainage.
Repotting: Hoya pubicalyx grows slowly, so it doesn’t need frequent repotting. Repot the plant every 1-2 years or when it becomes root-bound.
Potting: Choose a pot with drainage holes to prevent water from sitting at the bottom of the pot and causing root rot.

5. Fertilizing

Feeding Frequency: During the growing season (spring and summer), fertilize every 4-6 weeks with a balanced, water-soluble fertilizer diluted to half strength.
Avoid Overfertilizing: Too much fertilizer can cause excessive growth and prevent flowering. Reduce or stop fertilizing during the fall and winter months when the plant is dormant.
Feeding for Blooms: If you’re aiming for more flowers, use a low-nitrogen fertilizer, as this encourages blooming rather than leaf growth.

6. Pruning and Maintenance

Pruning: Prune any dead or leggy stems to maintain a tidy appearance and encourage new growth. If you want to propagate, simply cut a healthy stem with a few leaves, and root it in water or soil.
Cleaning: Wipe the leaves with a damp cloth to remove dust. This will help the plant “breathe” and keep it healthy.
Flowering: Be patient! Hoya pubicalyx can take several years to bloom, but once it does, it produces clusters of fragrant, star-shaped flowers.

7. Common Problems

Yellowing Leaves: Yellow leaves can be a sign of overwatering, poor drainage, or too much direct sunlight. Ensure the plant has proper drainage, and adjust watering as needed.
Leggy Growth: If the plant becomes leggy or sparse, it may need more light. Move the plant to a brighter location to promote more compact growth.
Pests: While Hoya pubicalyx is generally pest-resistant, it may occasionally attract mealybugs, aphids, or spider mites. If you notice pests, treat the plant with insecticidal soap or neem oil.

8. Toxicity

Pets: Hoya pubicalyx is considered non-toxic to pets (cats and dogs), making it a safe choice for households with furry friends.

By following these care instructions, your Hoya pubicalyx will thrive and reward you with lush foliage and stunning, fragrant blooms. With proper care, this beautiful vine will continue to grow and enhance your space for years to come!
