Hoya Pachyclada: Ultimate Grow & Care Guide

Hoya Pachyclada belongs to the dry tropical regions of Southeastern Asia and shows vigorous growth in their natural habitat.

However, if you are growing the plant outside its natural home, you may not see the blooms in time.

But you can grow them anywhere if you provide them with the conditions of their tropical home.

Image represents care tips for Hoya Pachyclada
Hoya Pachyclada is a tropical vine showing epiphytic habits and requires a balanced set of tropical cultural conditions to thrive.

1. Light and Temperature

Hoya Pachyclada is hardwired to climb on the surfaces of other tall trees as a vine plant to get as close as possible to the warm light source.

But at home care, you must watch for light and temperature changes, as Hoyas demand natural sunlight and naturally regulated ambient temperatures.

Hoya Pachyclada prefers direct morning or evening sun for 2 hours with surrounding temperatures between 70°F and 95°F at all times.
Image represents a Hoya plant under direct sunlight
Hoyas require minimum morning or evening sunlight hours to keep up with their growth.

However, Hoya cannot tolerate temperatures running below 50°F, and they can run into cold shock sustaining frost injuries.

Since light and temperature go hand in hand, increasing light intensity can increase the temperature and vice versa.

So, high or low-temperature stress can hamper the leaves, flowers, and roots, ultimately caused by lighting issues.

Effect of Excessive Light and Temperature

  • Bleached and off-color leaves (yellowing)
  • Marginal and tip burns
  • Wrinkling or drooping of foliage

Effect of Low Light and Temperature

  • Shriveled and floppy appearance
  • Lanky growth of the vines in search of light
  • Slow or stunted overall growth
  • Leaf and flower drops
  • Progressive yellowing of the leaves
  • Fewer blooms

Tips for Maintaining Adequate Light and Temperature

  • Place the plant near a south-facing window for 2 hours in the morning or evening.
  • Hang drapes in front of intense lighting windows to protect the plant from the blazing sun in summer.
  • If you live in cold regions, place your plant in the sun for a few hours or relocate it to an east-facing window for the day.
  • Keep the plant away from north-facing, drafty windows to protect it from cold air in winter.
  • Cool the plant in summer by gently misting it every few days.
  • Use LED lights for 10-12 hours, about 12 inches away from the Hoyas, to benefit them during fall or winter if the sunlight is insufficient.

2. Watering and Humidity

Hoya Pachyclada has succulent leaves and doesn’t need much water to sustain itself, but they eventually feel thirsty.

Additionally, Hoyas come from humid tropical forests where humidity is crucial in maintaining their growth.

It would be best to water Hoya Pachyclada every 5-10 days and cut off watering during fall and winter. Also, offer humidity levels between 50% and 70%.

High humidity may not pose a problem for this moisture-loving plant, but low humidity can subside the growth of its parts.

Similarly, overwatering can obstruct the function of their roots, and the effect of this problem gradually crawls on the shoots.

Effect of Overwatering

  • Floppy, wet leaves that fall off from the plant
  • Weakening of petiole base
  • Mushy or pulpy black to brown roots due to rot
  • Droopy foliage (inadequate water reaching the upper parts due to root damage)

Effect of Underwatering

  • Gradual yellowing and shriveling leaves
  • Brown leaf tips and margins
  • Dry soil with superficial cracks
Image represents Hoya plant with damage to the leaves
Underwatering can cause the cells of the leaves to die due to less reach of water leading to burnt margins and tips in Hoyas.

Signs of Low Humidity

  • Infrequent blooms and fewer flowers
  • Slow growth
  • Crispy leaves and topical burns on the leaf’s surface

How to Properly Water and Maintain Humidity for Hoya Pachyclada?

  • Place the overwatered Hoya plant in full sunlight for a few hours to let the soil dry.
  • If you suspect a foul smell from the soil, uproot the plant, check for root rots, and repot in fresh soil.
  • Let the soil and the roots dry at least 50% before watering the plant again.
  • Empty the saucer beneath the pot to prevent water stagnation.
  • Add organic perlite or sand to the soil for additional drainage.
  • Layer the bottom of the container with pebbles while repotting the plant.
  • Group the plants together or place the plant on a humidity tray to raise the humidity levels.

3. Soil and Fertilizer

Since Hoyas grow by attaching themselves to the barky stems of other trees, they are undemanding about the soil and nutrient needs.

This is because Hoyas fulfill their nutrient demand from the air but need a substrate base to fix their roots.

Offer Hoya Pachyclada with well-draining, fluffy soil with pH levels between 6.1 and 7.3 amended by balanced liquid fertilizer every 2 weeks in spring and summer.

Since Hoyas are light feeders, they don’t need fertilization in fall and winter as they stay dormant.

Too much fertilizer can halt the plant’s growth, sustaining gradual damage to the leaves and roots.

Similarly, if the soil is hard and clayey, it prevents water drainage and blocks the downward growth of the roots into the soil.

Effect of Overfertilization

  • Accumulation of fertilizer salts on the topsoil
  • Fertilizer burns to the leaves and roots
  • Difficulties in uptaking additional nutrients from the soil

Effect of Underfertilization

  • Changes in leaf color
  • Deformed leaves
  • Weak regrowth 

How to Provide Proper Soil and Fertilizer for Hoya Pachyclada?

  • Flush the soil 4-5 times with distilled water to remove the excess fertilizer salts.
  • If the symptoms persist, repot the plant with a fresh potting mix.
  • Fertilize the plant before watering so the nutrients can leach to deeper soil layers.
  • Always use the fertilizer of half-diluted strength to feed Hoyas.
  • Clear the drainage holes of the pot once a week.
  • To promote blooming, use NPK fertilizer in a ratio of 5-10-5.

To prepare a homemade potting mix for Hoyas, mix 50% peat moss, 40% organic perlite, and 10% pine bark with some water.

4. Periodic Repotting

As Hoya Pachyclada is a slow-growing epiphyte, you need not worry about repotting it frequently.

Remember the pot size you are planting since Hoya roots are shallow.

Repot Hoya Pachyclada every 2-3 years in early spring in a new 1-2 inches wider and deeper terracotta pot with bottom drainage holes.

Hoya Pachyclada can stress out with frequent repotting, which is bad for their roots. There is less chance that Hoyas will get root-bound, which takes time. 

So, waiting until the plant shows the following symptoms is better.

  • Roots poking out from the drainage holes
  • Cramming of roots on the topsoil
  • Stunted growth
  • Yellowing of the leaves due to less oxygen reaching the roots (pot-bound condition)

If the plant shows these signs, prepare to repot with these easy steps.

  • Water about 1-2 days before repotting to hydrate the plant and soil.
  • Take the plant out of the previous pot. Loosen the root balls gently and break the soil clumps.
  • Trim off the broken and dead roots in case of any damage.
  • Take a terracotta pot and fill 70% with the potting soil over a layer of pebbles.
  • Gently place the plant in the pot and dab the soil around the base of the plant gently.
  • Water the plant properly and place it somewhere with adequate light and good warmth.

5. Recurrent Pruning

Hoya Pachyclada is a climbing plant that takes the support of the stakes to grow.

So, the plant can sometimes grow long vines that dull its appearance and revert its energy, making it quickly outgrow its pot.

Additionally, the plant can have frequent feuds with pests (aphids, mealybugs, scales, and spider mites) and diseases (root rot, rusts, mildew, blight, and leaf spots).

So, a proper trim-off is necessary to reduce the disease incidence and spread of pests.

Trim the diseased, lanky, overgrowing plant parts and spent blooms using sterilized pruners now and then to preserve the energy for the next season’s growth.

The best way to trim a Hoya is to remove the flowers, dead leaves, and vines while keeping the flower peduncle, which acts as a flower base in the next season.

If any of the above symptoms are visible, gear up to prune your Hoya plant.

  • Cut the leaves and stems that appear lanky, diseased, off-colored, or stuffed with pests. 
  • If all or most of the leaves on the vine are heavily damaged, prune off the entire vine.
  • Remove the pests using Q-tips dipped in neem oil or apply broad-spectrum fungicides every 7-14 days to reduce the occurrence of diseases.
  • Burn the plant parts to cease the diseases and pests.

Hoya Pachyclada: All About Growth Rate

Hoya Pachyclada is a vining perennial epiphyte that grows slowly compared to other Hoya varieties.

They can grow to be one foot in height in about two years and a maximum of two feet in their lifetime.

The leaves are oval-shaped (ovoid), light to dark green in color, succulent, thick, marked by prominent veins on both sides, leathery, and about 6 inches in length.

Image represents the flowers of Hoya Pachyclada
Hoya Pachyclada produces creamy white and star-shaped flowers at the end of their vines with a sweet fragrance.

As a vine plant, they seek support for growing if you have potted them in a container. If you have hung them, the plant will be top-heavy.

You can stake the pot with a mini trellis to support the plant stem. The branches will get woodier as they age, so support may not be needed at the later stages.

The plant’s growth occurs throughout spring and summer, while the plant flowers between summer and fall.

Flowers are waxy, star-shaped, creamy white, and appear in clusters called umbels due to their groups resembling an umbrella.

One cluster can have 20-30 flowers, which can vary in color depending on the Hoya variety.

Besides, the flowers have a strong and musky fragrance that can lure pollinators like butterflies and bees. 

Soon, the flowers are replaced by spindle-shaped pods that contain seeds. 

Toxicity of Hoya Pachyclada

Hoya Pachyclada is a safe plant to keep in your household periphery.

Your pets and kids can enjoy playing with this plant without toxicity or poisonous risk.

Even ASPCA has not listed this plant on its list of toxic plants on its website.

However, it would be a safe practice not to let them come in contact with its milky/white sap.

Additionally, pets or children can accidentally bite on the plant parts, which may pose a choking hazard, and sometimes even worse.

To protect your pets, use deterrent sprays or cone your pets so they cannot nibble the plant parts.

For children, use tall shelves to keep the plants or hang the plants high above the ground. 

Propagation of Hoya Pachyclada

You can propagate Hoya Pachyclada successfully using stem cutting in spring or summer when the plant is actively growing.

Moreover, it helps the plant recover from the transplant shock and provides feasible growing conditions.

Propagate Hoya Pachyclada Via Stem Cuttings

Follow the steps below to propagate this plant by stem cutting.

  • Go for a 3-6 inches long healthy stem cutting with at least two nodes and three leaves.
  • Trim the stem just below the leaf node. Remove the lower leaves and expose the nodes.
  • Leave the cutting for a day to form a callous. 
Image represents the method of propagating Hoya Pachyclada
While propagating Hoyas, use a single pot to plant the cuttings to prevent overcrowding and even distribution of nutrients for the young growing plants.
  • Prepare a glass jar of water and place the cutting inside the jar.
  • Immerse the nodes in the water but leave the leaves outside.
  • Place the plant in bright, indirect light and change the water every 3-5 days.
  • New roots will grow in 2-5 weeks. Let the root be one inch long before moving it to potting soil.

In a 4-inch container, make a well-draining potting soil with perlite and peat and place the cutting to about root depth.

The cutting will take approximately three weeks to root. Cover it with a zip-lock bag to maintain humidity.

Use a single jar and single pot for each cutting to prevent competition and overcrowding.

Besides, Hoya can also be propagated using air layering, but it’s difficult. If you want to propagate the plant using air layering, take help from the following video.
