Hoya Pubicalyx Care

Thick, waxy leaves, long and reaching stems, and easy care requirements make the Hoya pubicalyx a marvelous houseplant. This wax vine variety is native to the Philippines and grows epiphytically in tropical climates. There are several varieties of pubicalyx that can be distinguished by subtle variegation and flower color. Like all Hoyas, the pubicalyx is low-maintenance, but here is what you need to know about Hoya pubicalyx care.

Public Knowledge

Hoya pubicalyx is often confused with another Hoya, the Hoya carnosa. Both plants belong to the same genus (Hoya) but are of different species. These plants are similar in appearance, but it can be hard to tell them apart, and you may see them mislabeled in stores or given a generic label, like ‘assorted Hoyas.’

Both plants have oval-shaped leaves that narrow to a point, known as lanceolate foliage. These are vining plants that are moderately fast growers. The leaves of the pubicalyx are slightly thinner and longer than the carnosa. Also, the pubicalyx foliage is often green with silvery-gray spots or specks. The pubicalyx leaves almost look like watered-down white paint was splashed on the plant. The carnosa, by comparison, have solid green foliage or variegation, like the Hoya Krimson Queen.

Pubicalyx Light Requirements

Medium to bright indirect light is best for Hoya pubicalyx care. Plants grown in bright indirect light will grow more quickly, so if you want to encourage your pubicalyx to grow long vines — find a sunny spot. Near a west- or south-facing window is a good location. You can always make a low-light area the perfect place using grow lights. Keep the pubicalyx out of harmful direct sunlight.

How Often to Water Pubicalyx

Hoyas are considered semi-succulents, which means they like to dry out between watering. Stick your finger in the soil, and when the top few inches of soil are dry, it’s time to water the pubicalyx. Saturate all of the soil until excess water runs through the container. Empty the cover pot or saucer of standing water.

Water frequency varies based on conditions like sunlight and humidity, but plan to water weekly during the growing season and every couple of weeks during the winter.

Soil Requirements

Give the pubicalyx rich, loamy, well-drained soil. High organic content is necessary to support this fast-growing houseplant. Drainage is essential to Hoya pubicalyx care because these stunners do not like wet feet.

Temperature for Pubicalyx

Temperatures between 65° and 80° F are best for Hoya pubicalyx care. The pubicalyx is a tropical plant that likes to be warm and is generally comfortable in most homes.

Be mindful of the temperature and sunlight if you relocate this beauty to an outdoor space for the summer. Keep the plant out of direct sunlight and get it inside if the temperature drops below 60° F.

Hoya Pubicalyx Humidity Needs

Hoyas do not crave increased humidity like prayer plants, but they still like some dampness in the air. Humidity around 60% provides ideal Hoya pubicalyx care. Average humidity is somewhat tolerable, but check the plant for dry leaves and be ready to give the pubicalyx a pebble tray or a humidifier if the conditions are too dry.

Pubicalyx Fertilizer

Hoyas, in general, including the pubicalyx, are not heavy feeders, but routine fertilizer applications are a good call. These plants prefer rich soil but also like to be rootbound, so fertilizing helps replenish the nutrients lost as the soil ages. Provide excellent Hoya pubicalyx care by fertilizing once monthly using balanced, water-soluble plant food.

Does Hoya Pubicalyx Bloom?

Hoyas are known for their lovely, star-shaped flowers. The blooms grow in clusters and give off a sweet fragrance. Hoya pubicalyx flowers can be pink or purple and may have red or black accents. Only mature plants bloom, and you can set your plant up for success by providing the best Hoya pubicalyx care possible.

When to Repot Hoya Pubicalyx

Hoyas like to be cozy and rootbound, and if you want your pubicalyx to bloom, then plan on allowing it to become rootbound. The pubicalyx is content living in the same pot for several years but will need fresh soil and a larger pot every few years.

Pubicalyx Propagation

Propagate Hoya pubicalyx via cuttings. Take a section of the stem and remove the lower leaves, exposing the nodes. Place the cut end in water or soil and wait. Water-propagated cuttings need fresh water weekly, while soil-propagated cuttings need consistent moisture. Roots typically appear in several weeks.

Is Hoya Pubicalyx Pet Safe?

The pubicalyx is a safe houseplant to have around pets. Your cat or dog will not become ill from eating any part of a Hoya. It is still advisable to keep the plant away from nosey pets to avoid damaging the plant, but your furry companion will not be harmed should they eat any part of a pubicalyx.

Hoya Pubicalyx Styling Tips

A pubicalyx will look good in just about any situation, but stick this beauty in a hanging planter and let some of the vines trail and train others to climb the hanger. The pubicalyx can do it all, and allowing the plant to both cascade and climb will create a full-looking, spectacular plant. Other plant styling options include providing a trellis or placing the plant on a shelf so the vines can hang down.
