How To Grow And Care For Hoya Wayetii

Hoya wayetii (HOY-a wy-et-TEE-I) is a fascinating member of the epiphytic Apocynaceae or Dogbane family of plants. There are more than 200 Hoya species.

The plants’ genus name, Hoya, honors 19th-century botanist Thomas Hoy. The origins of the specific epithet, wayetii, are unclear.

  •  Wax Plant 

Hoya Wayetii Care

Size & Growth

This slow-growing plant has a trailing growth habit. Individual tendrils can grow to be about 36″ inches long. As the plant trails along the ground’s surface, it rises to a height of about four inches. 

The leaves are thick, lance-shaped, about five inches long, and deep green with red edging. The amount of light the plant receives determines the depth of the red shading. There is also a variegated Hoya variety with green and yellow/white leaves.

Flowering & Fragrance

Besides its attractive foliage, Hoya wayetii also produces lovely, sweet-smelling clusters of mauve flowers in the springtime. Plants may not bloom for the first couple of years. 

When the plant has finished blooming, be careful not to damage the flower’s base (peduncles). Damaging these parts prevents blooming next spring. 

Light & Temperature

This type of Hoya needs a great deal of light. Bright, indirect light from dawn to dusk is best. Remember these plants are epiphytic, so they climb to the treetops to enjoy as much sun as possible in the wild. 

Your plant needs six hours of bright, indirect sunlight daily to thrive and bloom. The more indirect sunlight the plant receives, the more it will flower. 

Wayetii plants love lots of light, avoid placing your plant in direct sun as this causes leaves to burn. Instead, place the plant several feet away from a window with bright light.  

Once you’ve found the right setting for your Hoya, keep it there. These plants do not like to move around. Turn the plant a quarter turn every few days to ensure that the entire plant is receiving enough sun. 

These tropical plants like daytime temperatures between 60° – 85° degrees Fahrenheit. Nighttime temperatures should not drop below 50° degrees Fahrenheit.

This plant is winter hardy in USDA hardiness zone 11. 

Watering & Feeding

Like orchids, Hoyas do not like to stay wet or soggy. They are considered drought tolerant. 

Water using the soak-and-dry watering method. Give your Hoya a thorough watering whenever the potting mixture is almost dry.

NOTE: Use distilled water or rainwater for watering plants. If using tap water allow the water to sit for 24 before use.

It’s a good idea to hold your plant over a sink or tub and pour water through the soil. When the water is no longer dripping out the bottom of the pot or basket, return the plant to its sunny home. 

Never allow your Hoya to sit in water, as this will lead to root rot.

Unlike most other types of Hoya, this tropical plant prefers very humid conditions. If you can maintain a humidity level ranging between 60 and 80 percent, your plant will be happier. 

Hoyas, in general, prefer high nitrogen fertilizer, which encourages vigorous leaf growth. Before bloom, feed using a high phosphorus houseplant fertilizer (1-3-1 ratio) to encourage more blooms. 

Another option is to use natural fish emulsion fertilizer a couple of times a month throughout the growing and blooming season. Do not fertilize in the autumn or winter. 

Hoyas may enjoy an occasional top dressing of used tea leaves or coffee grounds. Compost or worm castings also make good top dressings for this plant.  

Soil & Transplanting

As an epiphyte, Hoya wayetii needs a  well-drained potting mix. A mixture of bark and coarse potting soil with a large percentage of perlite is recommended. 

Hoyas do well in hanging baskets. Avoid using a plastic hanging pot. An actual basket that allows good air circulation and lets water run through the soil mix is best. 

Failing that, use a container that has lots of drainage holes in the bottom. 

Do not repot this slow-growing plant very often. Hoyas like to be slightly root-bound.

Grooming & Maintenance

Pinch the plant back to encourage bushy growth. Remove old, dead, or damaged leaves and stems as needed. 

How To Propagate Hoya Wayetii

Hoya wayetii is easy to propagate with cuttings in the spring and summer.

Propagating In Soil

  • Make 5″-7″ long stem cuttings off with clean cuts below a leaf node
  • Remove lower leaves
  • Leave a couple or three leaves at the tip of the stem
  • Dip the base of the cutting in a rooting powder
  • Place the cutting in damp well draining soil.
  • Keep it in a warm, bright, still setting
  • Roots should start to appear within a month.
  • After a couple of months pass, transfer the plant to a small pot
  • Use a sharply draining potting soil and treat it as a mature plant.

Propagating In Water

If propagating in water

  • Make 5″-7″ long stem cuttings off with clean cuts below a leaf node
  • Remove lower leaves
  • Leave a couple or three leaves at the tip of the stem
  • Change the water every couple of days until strong roots have grown
  • Roots should start to appear within a month.

Growing Hoya in water is also possible. The plant can live happily in water for quite a while. Change the water every couple of days to prevent rot.

Pro Tips:

  • When propagating in soil, keep the potting soil slightly moist until new growth starts. Once new growth begins, reduce watering and treat the cutting as a mature plant.
  • Place several cuttings in a larger container to produce a bushy looking plant.

Propagate Hoya Using the Air Layering Method

  • Select a lengthy stem on a plant
  • Remove excess leaves
  • Bend the stem gently into a pot of fresh potting soil.
  • Anchor it in place with a stone or clip.
  • When the stem takes root in the “other” pot
  • Cut the stem away from the parent plant using a sharp, sterilized cutting tool.

Hoya Wayetii Pest or Disease Problems

If well cared for, Hoya wayetii are relatively trouble-free. Problems begin with:

  • Overwatered plants
  • Plants not receiving enough light
  • Plants without good air circulation

These conditions often allow plants to develop fungal infections.

A potting soil mix kept too wet attracts fungus gnats. Mealybugs may become problematic for plants weakened by unhealthy conditions.

Fungus Gnats

Fungus gnats do not harm plants, but their larvae (which live in the soil) do. To avoid a fungus gnat infestation, avoid overwatering.

If you find fungus gnats hovering over the top of the soil, try sprinkling some cinnamon over the soil surface.

The cinnamon will help kill off the fungus in the soil, which attracts the gnats. Consider adding a layer of pea-gravel mulch over the top of the soil to discourage the gnats.

For Hoyas infested with mealybugs, give the plant a vigorous shower to knock the adult bugs off. Quarantine the plant to prevent the spread of any stragglers or newly hatched mealy bugs. 

Treat the plant with a horticultural oil solution or Neem oil insecticide spray to prevent further infestation. Repeat this treatment weekly for a month or so to be sure of success. 

Rarely, Wax Plant may contract Tomato chlorotic spot virus. [source]

Is The Wayetii Hoya Considered Toxic or Poisonous?

Hoya plants are related to milkweed and contain a similar white, milky latex sap.

Some people have allergic reactions to this sap, and contact with it can cause skin irritation. Ingestion of the juice may also cause gastric distress.

Keep your Hoya out of the reach of pets and children. Wash your hands after handling the plant.

There is no indication that the Hoya plant is invasive.

Suggested Hoya Wayetii Uses 

Hoyas are excellent choices as a potted, summertime, outdoor plant, or a year-round house plant. Because of its trailing habits, it does very well in a hanging basket.

These plants love humidity and can make excellent bathroom plants with ample lighting. In a tropical setting, use the plant as a ground cover under trees that provide high shade.
