How to Grow and Care for Hoya Waymaniae Borneo

Among the diverse world of Hoyas, the Hoya waymaniae ‘Borneo’ is a sought-after specimen for plant enthusiasts. Originating from the humid, tropical rainforests of Borneo, this epiphytic climber has gained popularity for its unique foliage and striking flowers. Its appeal lies in its distinct visual characteristics, which offer a different texture and color palette compared to more common houseplants. This plant grows at a relatively slow pace.

Identifying Features of Hoya Waymaniae Borneo

The most captivating aspect of Hoya waymaniae ‘Borneo’ is its remarkable foliage. The leaves are thick and succulent, featuring a distinctively rough or velvety texture and wavy edges that add to their sculptural quality. New leaves emerge with a bronze or reddish coloration, maturing to a deep green. This plant is also known for its ability to “sun-stress,” a process where the leaves develop deep red and purple hues when exposed to high levels of light.

The flowers of this Hoya are as unique as its leaves, growing in clusters of small, star-shaped blooms. Each flower is a vibrant shade of orange or reddish-orange, with some variations showing a darker red or pink center. The blooms have a fuzzy or finely haired texture and emit a light, sweet fragrance compared to honey, which can fill a room. While bringing the plant to flower can be a challenge, the appearance of these colorful clusters is a rewarding sight.

Essential Care Requirements

Light

Proper lighting is a significant factor for the health and appearance of Hoya waymaniae ‘Borneo’. This plant flourishes in bright, indirect light, and an east-facing window with gentle morning sun is ideal. This encourages the vibrant sun-stressed colors without scorching the leaves. While it tolerates lower light conditions, its growth may become slower and the foliage will remain green. Avoid harsh, direct afternoon sun, which can cause leaf burn.

Water

As an epiphyte with succulent leaves, Hoya waymaniae ‘Borneo’ is sensitive to overwatering. The best watering strategy is the “soak and dry” method. This involves watering the plant thoroughly until water drains from the pot, and then allowing the soil to dry out almost completely before watering again. Yellowing leaves or a mushy stem base are indicators of overwatering, while wilted or limp leaves are a sign that the plant is ready for water.

Soil

The right soil mix is important for preventing waterlogged roots. Hoya waymaniae ‘Borneo’ requires an extremely airy and well-draining potting medium. Standard potting soil is too dense and should be avoided. A chunky mix composed of orchid bark, perlite, and a small amount of potting soil works well to provide the necessary aeration and drainage, which allows the roots to breathe.

Temperature and Humidity

This plant thrives in conditions that mimic its native tropical environment, preferring warm temperatures between 65°F and 80°F (18°C to 27°C). It should be protected from drafts and sudden temperature drops. Hoya waymaniae ‘Borneo’ also appreciates high humidity levels between 50% and 70%. Using a humidifier or placing it in a naturally humid room like a kitchen or bathroom can promote more vigorous growth.

Fertilizer

To support its growth during the active seasons of spring and summer, regular feeding is beneficial. A balanced, water-soluble fertilizer diluted to half-strength is a suitable choice and should be applied every four to six weeks. Some growers opt for a fertilizer with a higher phosphorus content to encourage blooming. Cease fertilization during the fall and winter, as the plant enters a dormant period.

How to Propagate Hoya Waymaniae Borneo

Propagating Hoya waymaniae ‘Borneo’ is successfully done through stem cuttings. First, select a healthy vine and use clean scissors to take a cutting that is at least six inches long and includes several leaf nodes. Make the cut just below a node, as this is where roots will form. Prepare the cutting by removing the leaves from the bottom one or two nodes to prevent them from rotting. This exposes the nodes and readies them to produce roots.

The cutting can then be placed in a rooting medium like water, sphagnum moss, or perlite. Place the container in a location that receives bright, indirect light and maintains a warm temperature. If rooting in water, change it weekly to keep it fresh. Roots begin to develop within a few weeks to a month. Once the roots are at least an inch long, the new plant can be potted into an appropriate Hoya soil mix.

Growth Habits and Troubleshooting

Hoya waymaniae ‘Borneo’ is a natural vining plant that will trail or climb. Providing a trellis or moss pole can encourage this natural climbing behavior. This supports the plant’s weight as it grows and can also lead to larger leaf development. Regular pruning can help manage its shape and size.

This Hoya can be susceptible to pests, particularly mealybugs and aphids. These insects are often found clustered on new growth or the undersides of leaves. Manage them by wiping the pests off with a cotton swab dipped in rubbing alcohol or by spraying the plant with insecticidal soap. A failure to bloom is often linked to insufficient light, so moving the plant to a brighter location can encourage flower buds.
