1. Adequate Sunlight and Proper Location

Hoya lacunosa grows naturally on the surface of any plant or tree with enough sunlight and shade. So, to grow it as a house plant, you need to place it under sufficient indirect light.

To grow properly, Hoya lacunosa requires at least an hour of direct sunlight, followed by 2-4 hours of indirect sunlight.

You can also place it in the garden under the sunlight. However, it needs some shade as direct sunlight can harm its waxy leaves.

Their waxy leaves require bright indirect lighting for their proper growth and development. It can grow under artificial lighting, but the plant might not bloom well.

When the plant is grown in artificial lighting settings, your plant might face problems like delayed growth of flowers with dull colors as compared to natural lighting.

The ideal location to place the plant would be in the patio porch of the house, where it receives indirect light.

Symptoms of Insufficient Lighting

  • Insufficient lighting reduces the photosynthesis in plants, leading to low energy and food for them.
  • It affects their overall physiological activities.
  • The leaves of the plants turn yellowish.
  • The whole plant begins to drop.

For cases when your Hoya plant exhibits such symptoms, an ideal solution can be placing the plant outdoors for a few hours to resolve this issue.

Symptoms of Light Saturation

  • Light saturation can cause excess intake of nutrients, which can cause nutrient build-up, which can lead to nutrient burn.
  • Excessive nutrient build-up can lead to nitrogen toxicity, turning leaves into dark green color.
  • Other symptoms of light saturation include browning of leaves a burnt appearance.
  • Leaf bleaching is another symptom caused by light saturation in which the top leaves that receive excessive light are yellow compared to the rest.

Tips to Maintain Adequate Light

  • Place your plant near the south-facing windowsill, covered with window covers.
  • Use artificial lighting sources like LED, GROW, or fluorescent lights during cloudy or winter days.
  • Avoid moving the plant drastically to a setting with different lighting conditions.
  • Make use of shade cloths window blinds to protect the plant from direct sunlight.

2. Watering Requirements

The watering needs of Hoya lacunosa are not exactly known.

However, observing the natural watering process is the safest bet to know the watering needs of any plants.

Since the watering needs vary according to the environment (temperature, sunlight received, and humidity levels), you need to be cautious while watering the plant.

Hoya lacunosa requires watering once a week during the summer and twice a month during the winter season.

Store rainwater during the rainy months to water the plant; it contains minimal chemical contaminants like chlorine calcium.

Since the soil in the forest area has excellent drainage, Hoya lacunosa receives adequate watering on rainy days, but the soil is never waterlogged.

Along with the proper watering requirement, proper drainage is equally important as it helps drain the excess water in the roots and prevents root-related issues and bacterial growth.

So, the key takeaway is that you can water your Hoya lacunosa more in a week but will need a potting mix that drains well.

So, how do you know when to water your Hoya lacunosa? Water the plant when the top layers of potting soil become dry.

Quick Tip: Dip your finger one to two inches into the soil. If it appears dry, water your plant.

Symptoms due to Improper Watering

  • Underwatering can cause the plant to lose turgor which is the rigidity in cells and tissues.
  • Leaves of plants like Hoya lacunosa will turn yellow when the plants are too dry.
  • The tip of the leaves will start to turn brown, and eventually, the whole leaf will turn brown and dry.
  • The plant will grow slower than usual.
  • The wilted leaves of an underwatered Hoya will be dry and brittle.
  • Overwatering might sometimes cause buds to fall off before flowering. It may even stop your plant from ever budding.
  • Root rot and foul smell from the soil are also overwatering signs.

Tips to Water Properly

  • Make sure to use water at room temperature. Using hot or cold water can cause damage to the plant and may affect absorption.
  • Use soil moisture meter to check the soil moisture.
  • Avoid using water rich in salts minerals as it can lead to accumulation in the roots.
  • Ensure that the saucer placed below the plant to collect water is emptied when enough water becomes accumulated.
  • In winter seasons, the plant remains dormant, so you need to cut back on watering the Hoya lacunosa. The plant needs some watering to survive, even though you won’t get a full bloom in winter.

3. Ideal Temperature

Hoya lacunosa is tolerant to most temperatures. However, it cannot stand extreme cold temperatures.

Ideally, it grows best between 68-77ºF. But, a temperature below 50ºF is fatal to the plant.

The plant can be grown outdoors if you live in a warmer climate like in the equator.

However, the plant should be protected from cold winds and temperature drops during winter. So, you should keep the plant indoors during such conditions.

Symptoms of Temperature Stress

  • Cold drafts can cause Hoya lacunosa’s leaves to turn yellow.
  • Higher temperatures cause the plant to shed some leaves to save water.
  • The leaves of succulents turn mushy when frozen.
  • When under temperature stress, the tips of succulents will turn red.
  • Sunburnt plants will have brown leaves or have a callus on their leaves.
  • A plant that has lately been sunburned will still have thick, full leaves that have started to turn black or brown and are shiny.
  • Older sunburns will be black or brown, dried or shriveled, or entirely desiccate.

If you notice that your lacunosa’s leaves have different colorations,n place them in optimal temperature, i.e., protect them from extreme heat or cold temperatures.

Tips to Maintain Ideal Temperature

  • Use an air conditioner to regulate temperature for indoor plants in summer and winter.
  • Try to boost the humidity level around the plant when the surrounding temperature is high.
  • Do not place your plants near the window in winters as frost and temperature change is more frequent in the season.
  • In case you are leaving your plant outdoors, cover them with plastics insulating bags.
  • Avoid placing your plant near fans, vents, air conditioners, and heaters.
  • If you are placing the plant outdoors and the temperature drops up to 55 ºF, it is best to carry the plant indoors to ensure that it survives in the winter. 

4. Ideal Humidity

Hoya lacunosa thrives in a natural environment with mild to high humidity. They grow upwards up to 60% when they receive heavy rainfall in nature.

Hoya lacunosa requires 50-60% and above humidity for optimum growth.

Maintaining relative humidity levels above 60% can be difficult to replicate within normal household conditions.

It’s challenging to grow this plant in the winter season. So, if you live in cold and dry places, ensure enough humidity by placing a humidifier in your room.

However, do not place the Hoya lacunosa near AC or heaters as it further dries out the plant’s soil.

The plant thrives in a humid environment rather than being waterlogged through the heavy watering of the plant.

Symptoms of Lack of Optimal Humidity

  • Low humidity can cause Hoya lacunosa’s leaves to wrinkle.
  • Fungus Phomopsis and other black sooty fungi attack the plant when placed in a highly humid place for long periods.

Tips to Maintain Ideal Humidity

You can maintain the ideal humidity for Hoya lacunosa by following ways:

  • Planting them in enclosed spaces like a greenhouse help to retain moisture.
  • To increase the overall humidity around the pot, you can also place a wet pebble tray around the plant.
  • You can group the plant with other plants, increasing natural precipitation. But be aware since grouping several plants also increase the risks of pests infestations.
  • Placing the plants in more humid areas such as bathrooms and kitchens can be beneficial.
  • Mist the leaves of your Hoya lacunosa to increase humidity.
  • Using a humidifier can be expensive but is highly effective and worth the price.

5. Slightly Acidic Soil Mix

Hoya lacunosa is a slow-release plant, so they grow better in the organic mix than chemical fertilizers.

The plant needs a potting mix that drains and aerates well. Organic solid with a good mix of compost, worms castings, and other matters are best suited for the plant.

It prefers a slightly acidic soil pH around 6.1-6.5.

Using grounded coffee beans can help make the soil more acidic.

The plant prefers a porous potting mixture, allowing oxygen exchange in the roots. Including substances like perlite, pine bark, peat moss, and organic materials can help improve the soil’s drainage.

Confused and couldn’t decide on How to Choose the Suitable Hoya Plant Soil? Well, this is how you should be done.

It should have a potting medium that retains moisture well but should also be well-draining.

Using hanging baskets to grow the plant adds to its aesthetic nature even more. While using hanging baskets, make sure to use cocoa fiber liners to hold the potting mixture properly.

However, the soil should be changed every two years for proper nutrition.

Tip: Use some succulent or orchid potting mix and combine one part perlite with two parts of the mix for a simple fix.

You can also find the ideal potting mixture for your Hoya lacunosa on Amazon. Here are some recommendations for you:

6. Fertilization Requirements

Hoya lacunosa fertilization occurs all through the year.

The summer and spring seasons are the best times to apply fertilizer to the Hoya.

Fertilize Hoya lacunosa once or twice during the summer and stop the fertilization entirely during the winter.

Or you can fertilize the plant with a half dose of liquid fertilizer is in the winter seasons. But fertilizers in the winter may cause salt build-up in the solid, and you may sometimes need to leach the soil.

Liquid-based plant food is mainly used for Hoya plants as the application is more effortless. The liquid fertilizer also reaches directly to the roots.

A balanced fertilizer with an NPK 20-20-20 proportion would be the best for the plant.

Using water-soluble fertilizers such as ‘Southern Ag-Power Pak’ annually during the summer can be beneficial for the plant.

When fertilizing the plant, always dilute the fertilizer by adding 1 part water for 1 part fertilizer (1:1 ratio).

Diluting the fertilizer helps reduce the risk of chemical burning caused by the excess use of chemicals in the fertilizer. Liquid Fertilizers can be added to the water while irrigating; once per month.

Time-release granules are an excellent option for Hoya plants; they contain tiny capsules that release fertilizer over time.

Another interesting fact about time-release fertilizers is that they are released every time the plant is watered, providing a constant source of nutrients.

Ensure not to fertilize the plant excessively as it leads to the accumulation of salts, leading to the chemical burning of the leaves and roots.

7. Growth Habits and Dormancy

Hoya lacunosa goes naturally into a semi-dormant stage in the winter months. Environmental changes cause the plant to be dormant for a few weeks or even months.

They do not shed their leaves or show any dramatic changes when dormant, but the plant stops growing in dormancy.

Therefore, adjustment is needed whenever the plant is brought into a new environment.

During dormancy, cut down the watering and fertilizing schedule of the plant as it does not require many nutrients for growth.

Growth Habits

Hoya lacunosa is a moderately slow-growing plant and does best in a medium-sized container.

If it receives proper growth conditions, it can grow up to 2-4 feet tall within a few years. 

Using a hanging basket is ideal for the plant regarding its look and growing pattern. It looks very similar to a pendant plant when hung in a basket.

Since it is a vine that grows on trees, it can quickly grow on walls and solid surfaces of the household garden.

Plant Foliage

Hoya lacunosa has tiny ovate or lanceolate leaves that are generally dark green. The areas between the veins are slightly sunken, which changes the otherwise flat surface.

The leaf blades are shiny and long, filled with stems rooted around the nodes.

It makes the plant perfect to be grown in hanging baskets, which allows the vines to grow properly.

Speaking of the foliage; have you heard about Best Small Leaf Hoya Plants?

Flower Shape and Colour

The blooms of Hoya lacunosa have a Cinnamon-scented fragrance. The flowers are mostly white, cream or tan colored.

Hoya lacunosa has the most attractive flowers: flat, button-shaped, white in color, and covered with about twenty convex pendant flowers.

Each of the flowers has a small ball of white center with a yellow outline which looks similar to a crystal. This cluster is only visible in mature flowers and does not open in the young, maturing flowers.

The flowers bloom in the summer and spring, which provides a beautiful visual for your plant collection. These flowers have a waxy structure in the middle leading to its name, waxflower.

Be careful not to remove the plant’s white center (peduncles), as new flowers can grow in the following summer and spring from it.

8. Potting and Repotting Hoya Lacunosa

Hoya lacunosa does not need to be repotted frequently, and it prefers to remain root-bound.

So, use a pot with draining holes for growing this plant. A tiny 4″ pot will last around six months for early cuttings.

After that, you can move it to a 10-inch hanging planter, where it will likely last at least two years.

The ideal container for the plant would be clay, terracotta, or plain plastic container.

If you need to repot it, lift the plant and the root ball whole and place it in a larger pot with fresh potting mix.

Repotting your Hoya lacunosa

Since the plant does not grow rapidly compared to other Hoya species, it can be repotted every 2-3 years to ensure proper growth.

Being root bound can be beneficial for lacunosa to bloom more flowers and leaves.

Repotting also encourages the plant to grow new leaves and develop better flowering traits than its previous container.

While repotting, you can use a container 2 inches larger in diameter than the original, which provides more than enough space to grow into.

Seeing the soil completely matted with hardened roots, roots coming out from the drainage holes, is the time to repot the plant to an enormous container. 

Watering and repotting plant

This indicates that it is now time to repot the plant to an enormous container. Another reason to repot is when the nutrients in the soil mixture get depleted.

Frequently fertilized plant needs a change of soil mixture every 2-3 years due to the natural exhaustion of nutrients in the soil.

The ideal time to repot the plant would be just before summer, spring which is its active growth season and has survived the cold winter.

Tips to Repot Hoya lacunosa

  • Loosen up the potting mixture by using a blunt knife.
  • Gently, remove the plan from the old pott, including the root ball.
  • Separate the soil from the roots, but do not untangle the roots.
  • Look for any indications of disease or pests and get rid of them using pruning or pesticides.
  • Place the plant in the new sterilized container and fill the top layer of the container with potting mix.
  • Fill the soil around the plant and lightly tap the soil to remove any air pockets. Then, lightly tap the hard surface to settle the soil.
  • Water the plant sparingly and place it in an indirect sunlight location.

9. Pruning Habits

Pruning Hoya lacunosa is not a necessity for the plant to encourage blooming.

Prune Hoya lacunosa only when needed. You can also trim the plant if you wish to propagate it or avoid overcrowding.

Trim the unhealthy leaves in spring and summer to keep them fresh through the year.

Leggy stems, narrow stems, undesirable foliage, dead, damaged, or missing leaves can all be removed by pruning. Only prune after it has stopped blooming since buds form at the ends.

Do not prune the flowers, which are fading slowly; it might induce delayed flowering in the next season. Instead, let the flowers drop on their nature to ensure proper growth.

Tips to Keep in Mind while Pruning

  • Make sure to use safety goggles and gloves for extra protection as the plant is toxic to humans.
  • Sterilizing the pruning materials before usage helps prevent bacterial, fungal diseases through the cut site.
  • Avoid pruning Hoya during the growing season as it affects the growth rate and delays the new growth of buds and flowers.
  • Make sure to place the plant out the reach of pets and children, ideally at a high location (shelves, window sills).
  • Always discard the pruned parts of the plants properly into the dustbin by covering them with newspaper as pets may accidentally ingest the plant.
  • Prune only dead and discolored foliage, buds, flowers, and stems.
  • Excessive pruning should be dodged as it can cause stalled growth and stress for the plant.

10. Hoya Lacunosa Toxicity

Hoya lacunosa is considered to be mildly toxic though not poisonous. It is recommended not to chew off the plant leaves.

It contains a unique sap that acts as a natural deterrent from predators in the wild. Confusing the plant leaves in large quantities can cause stomach irritation and nausea.

Ideally, the plant should be placed in safe locations such as high shelves enclosed areas that children or pets cannot easily reach.

Hoya lacunosa produces white Latex in its foliage which is harmful to humans and animals.

Seek veterinary medical assistance if you or your pet ingest any part of Hoya lacunosa.

For pets, you can consult a local veteran or Call the APCC at (888) 426-4435.

Consider the following tips while handling toxic plants:

  • Wash your hands right after intentionally or accidentally touching the plants.
  • Keep the plant out of reach from children and pets.
  • Don’t ingest or let anyone ingest the plant.
  • Wear gloves while propagating or pruning the plants

Propagating Hoya Lacunosa

Ordering a new plant each time can be costly; the effort required to grow it from scratch is also time-consuming.

You can simply propagate a new plant from the older plant using propagating techniques.

The best method to propagate Hoya lacunosa is by using stem cuttings and seeds; they can be propagated in water and the soil potting mixture. 

Propagation is the simplest and most cost-effective method of growing new plants that are genetically similar to the parent.

Quick Note: Plant enthusiasts often prefer stem cutting method of propagation as it is much easier as compared to seed propagation.

The most suitable time to propagate the plant is around the beginning of summer.

Immediate Check before Propagating

Ensure that you have all the required materials for propagation, mainly:

  • Sterilized gardening equipment (pruning shears, blunt knife)
  • Protective clothing (gloves, full covering clothes)
  • Proper potting mixture
  • Water

Thoroughly check the plant for any pests or diseases to ensure that you are propagating a healthy plant. You wouldn’t want to propagate a diseased plant and spread more diseases.

1. Propagating through Seeds

Growing Hoya lacunosa with seeds is not preferred by many plant enthusiasts, as it takes a very long time and requires more care and effort.

Also, if the seeds used in propagation are not mature, fresh there are even fewer chances of proper propagation.

Simply place the seedlings in a damp medium and cover them with a proper potting mixture, peat moss, and sphagnum.

Ensure the seedling’s soil is warm, moist, and has proper lighting to ensure proper growth through seeds.

Note: If you are propagating through seeds, it can be prone to fungal infections, snails, and slugs attacks.

2. Propagating through Stem Cuttings

Propagating through stem cutting is much easier and requires less time effort.

The stem propagation can be either in the potting mixture or in water to induce rooting and later be transferred into a potting mix.

Step by Step Guide for Stem Cutting Propagation in Potting Mixture

  • Sterilize the garden scissors, sponge, and fine bark chips beforehand.
  • Make sure to prepare sterile and clean potting mixture for the new plant.
  • Then, cut a few short stems which have some nodes.
  • Place the stems straight up in the soil and cover the nodes entirely with soil.
  • Mist the potting mixture frequently to create a moist environment for the soil, but make sure not to oversaturate the soil.
  • Lightly tap the soil around the new stem and place it in a direct sunlight location.
  • The root development should take place in about two to three weeks, after which it will begin to produce vines.

Step by Step Guide for Stem Cutting Propagation in Water

  • Like the above steps, choose a stem with nodes present on it.
  • Remove the leaves from the plant stem towards the lower end, which is to be dipped in the water.
  • Then place the stem cutting in a container filled with tap water. Let the water stay overnight to allow the chlorine to settle down.
  • Now, dip the stem cutting around four inches deep into the water and allow the nodes to become completely submerged.

Common Problems with Hoya Lacunosa

1. Pests Infestation

Hoya lacunosa is usually disease and pest-free but can sometimes get root rot and mold.

Pests like mealybugs and spider mites usually trouble Hoya plants. Likewise, aphids like oleander aphids, oat bird cherry aphids also infest the plant. 

Mealybugs infesting the plant

Larger bugs like red spiders, grasshoppers, slugs, snails, and rodents can also attack if your plant is kept outdoors.

  • Red spider mites are tiny insects that hide under the leaves, making them difficult to locate. Instead, you can look for the damage (discoloration, speckling, and white webbing around leaves) caused by the pest.
  • Mealybugs are tiny insects feeding on the plant sap and tend to cover the leaves stems with waxy secretions that affect the plant’s growth blooming and flowers.
  • Aphids are tiny insects that secrete a substance known as honeydew, which attracts mold spores, leading to various types of fungal infections.

You can get freed from most pests by improving the humidity and using miticide on the plant.

Treatment Measures

  • Check for bugs under the loaves and nodes to remove the infestation earlier.
  • Mealybugs can be removed by using cotton balls dipped in isopropyl alcohol.
  • Using a homemade mixture of 1 part rubbing alcohol, four parts water, and a few drops of dish wash soap and spray on the pest-infested parts of the plant.
  • Use neem oil, water, and soap mixture, then spray on the leaves soil to ensure pests’ eggs are destroyed.

Preventive Measures

  • Ensure to thoroughly check the plant for any signs of infestations before introducing it to other plants.
  • Always use clean, pest-free soil and propagation tools while handling the plant.
  • Mealybugs can also be removed using strong water spray; it also discourages them from infesting the same plant in the future.
  • To establish a greenhouse-like atmosphere and avoid insect infestations, cover the plant with a plastic bag with holes while propagating.

2. Diseases Infestation

Generally, like other Hoya species, the Hoya lacunosa is also quite resistant to diseases.

But it does demand some care and effort from time to time to protect it from common diseases which can be easily avoided.

A few of the diseases common in Hoya lacunosa are Phomposis and Black Sooty Mold, which appear on the flowers. 

When Hoya lacunosa is left in a humid place for an extended period, it is attacked by a fungus; PhomopsisThe plant’s veins turn yellow or fade when infected.

Another disease that affects the plant is Sooty Mold, caused by black fungus species when exposed to high humidity for an extended period.

The primary reason for sooty mold is a direct result of aphid infestations in high nectar-producing flowers, which leads to honeydew production, ultimately increasing mold infections.

Sooty mold covers the host plant in which it lives and blocks light, reducing the efficiency of photosynthesis.

This mold attaches to the growing surfaces such as the barks’ stems and absorbs moisture through these surfaces.

The large growth of sooty mold can lead to excessive dehydration leading to the death of the plant. Also, lead to the yellowing of the foliage as an outcome of moisture loss.

Most of the diseases in the plant are due to overwatering excessive moisture in the soil, which works as a breeding ground for bacteria fungus to grow and spread diseases.

Treatment Measures

  • Remove the infected portions of the plant to prevent the spread of disease to other parts of the plant.
  • Make use of fungicide to reduce and manage fungal infections diseases.
  • After pruning repotting the plant, permanently remove contaminated soil and diseased parts of the plants.

Preventive Measures

  • Work on a suitable watering schedule for the plant.
  • Separate any infected plants away from the Hoya plant.
  • To save your plant from this Phomopsis, you should keep your soil sterile and moisture-free.
  • Mold, fungal growth tends to be highest when the plant is watered, misted during the evening; avoid it at all costs.
  • Spraying the plant with fungicides annually helps prevent fungal growth around the leaves’ roots.

Take care of the plants if you see any signs and symptoms and provide proper care to improve plant health.
