Hoya Curtisii

About Hoya Curtisii

The Curtisii is a species of flowering plants in the family Apocynaceae. This vining plant grows well in USDA zones nine and ten. The most distinguishing feature for this type of hoya are its thick, leathery leaves that range from dark-green to deep purple on the vine’s aged stems. It does not produce any flowers or fruit but produces an extensive root system which can grow up to two meters long.

Light Requirements

Hoya Curtisii can grow best in direct sunlight for about four to six hours a day, but will still produce flowers under artificial light. The leaves of the plant should not be exposed to any scorching hot sun and need at least one foot open space on all sides. This is so that it does not overheat during the summer months when temperatures are higher than normal in your area.

This type of hoya only grows well if you mist its leaves once every three days with room temperature water because they absorb moisture through their thick waxy cuticles. They also require regular fertilizing twice per week or giving them an organic fertilizer monthly, which usually consists of nitrogen-rich materials such as manure tea, compost or even animal droppings.


Mist Hoya Curtisii two to three times per week. Do not allow the soil to become dry and do not overwater. Watering should be easy as they don’t require a lot of water, but will need some help in humid environments or during droughts.

The best way to tell if your plant needs watering is by checking on its leaves; this is where you can see signs that it might be time for an irrigation cycle because the leaf surface has changed from glossy to matte or dull.

You may also notice droplets forming on the underside of the leaves after misting them with water, which indicates that these plants have been watered often enough up until now and are thirsty at this point!


Hoya Curtisii is a subtropical species that grows in Southeast Asia. The plant prefers temperatures between 65 and 85 degrees Fahrenheit, with the ideal temperature being 70 to 75 degrees. Temperatures lower than 60 or higher than 95 will likely kill your plants. Hoya does not like sudden changes of temperature either so try to make sure they are at their desired level before going out for long periods of time.

Pot Size

In order to reach their full potential, Hoya plants need plenty of space. When planting in a pot, we recommend using pots that are at least 12 inches deep and have drainage holes on the bottom. The width is not as important because you will be able to move your plant around so it gets good light exposure from all angles without needing to move the pot.

Hoya Curtisii Fertilizing

Fertilizing a Hoya is essential for healthy growth and maintaining balance in the plant’s environment. There are many fertilizers available on the market, but they can be expensive so it is best to buy them at local stores. Organic fertilizer should be purchased if possible because of its health benefits. The most common type of organic fertilizer for Hoya plants is an organic liquid fertilizer.


When it comes to humidity levels, this hoya likes humid days but dislikes wet ones. Too much water can cause root rot and other problems so be careful when watering them! This means you should place them near windows where they get some natural light during the day instead of placing them on a shelf overlooking an interior courtyard.

Pruning requirements

Hoya plants should be pruned at the end of their growing season, when they are no longer producing new leaves. To do this, cut off any dead or dying branches and shorten long stems back to where they branch out from a stronger stem; you can also use scissors if it’s easier for you to work with.

This process will remove old flowers which may have become diseased, as well as any unhealthy parts of the plant that could carry disease into next year’s blooms.

Deadheading is important not just because of aesthetics but also because removing these spent flowers ensures there is more food going towards healthy growth. It’ll give your plant more energy so that in their natural state they can work to produce new flowers for you.


Some important things you should know about propagating your own Hoya curtisii plants are to use a shallow container and potting soil.

A good mix is equal parts of sand, peat moss, vermiculite or perlite (all three provide excellent drainage), organic matter such as compost or leaf litter, and your regular garden loam. If you’re using the latter two as part of the mixture then make sure it’s not too dense so that water will drain out well.

The optimal planting depth for Hoya Curtisii should be around an inch deep where they can remain undisturbed through their first winter before going dormant in late autumn each year until spring when they sprout new leaves again from emerging buds on healthy stems beneath ground level.

I recommend transplanting them into larger pots about a year after transplanting them to a shallow pot. It’s important that you water the surface of the soil and not pour water over the leaves or stems, which may cause rot.

A monthly application of fertilizer will be sufficient for fertilizing needs in warm climates where they are happiest.”

Hoya curtisii care should include allowing its roots time to adjust before being transplanted into larger pots when it is about 12 inches high with at least one foot long stem.

When watering Hoya Curtisii plants make sure that you do so cautiously as too much moisture can lead to mold and other fungal problems. Fertilize once per month by applying a liquid plant food diluted according to manufacturer directions (usually half-strength).”

Potting Soil Mix Suggestion

Use a fast-draining substrate such as cacti mix sand mixed with some organic material like leaf mold peat moss potting mix or compost for pot culture.

Soil Care

Loose, fast-draining medium such as cacti mix sand or pumice stone mixed with some organic material like leaf mold, peat moss, potting mix, or compost.

Is This Plant Toxic Or Poisonous?

Generally, Hoya plants are not considered toxic or poisonous.

Other Hoya Varieties and Names

Hoya Carnosa is also known by the common name of wax plant. It has a succulent and fleshy texture with thick, waxy leaves that grow in clusters on long upright stems. Wax plants typically have blooms which are small buds or elongated spurs that may be pinkish to rose-colored; it’s not unusual to see a wax plant with yellow, cream, or white blooms.

Hoya Kerrii is an Australian native that grows as a vine up the sides of trees and plants. The flowers are tubular and grow at the end of long pedicels that arise from leaf axils; they may be pinkish-red in color.

Hoya Pubicalyx is a native of southern India and Sri Lanka, with red flowers which are found at the end of long flower stems that arise from axils on the leaves. This variety grows into a small shrub or climber with petioles up to about 12 inches (30 cm) in length which forms a rosette at the end.

Hoya Erythrospatha is a native of Madagascar and has long, slender leaves with red flowers that are found along its length. This variety will reach about two to four feet (a meter or so) in height when fully grown and can be propagated by cutting sections from runners which have grown from the plant.

Hoya Morrisii is a native of Mauritius and has distinctive flowers which are yellowish-white with red centers that grow on long stems; they can reach up to about four feet (a meter or so) in height when fully mature and will need some support, such as being planted near a fence or wall.

Hoya Sexangularis is a native of Sri Lanka and has dark green, oval leaves with purple flowers that are up to about an inch (about three centimeters) in length which grows from the leaf stem nodes; this variety can reach two to four feet (roughly one meter or so) in height when fully grown.

Hoya Arborescens is a native of Singapore and has green leaves which are about one inch (three centimeters) in length with white flowers that grow on long stems. This variety can reach up to five feet (roughly two meters or so) in height when fully grown.

Why Are My Hoya Leaves Turning Yellow?

Sometimes leaves of the Hoya plant turn yellow and drop off. This is a natural process in which excess nutrients are given to new buds, often resulting in flowers that bloom at an earlier age than usual. As long as there are stems left on your hoyas, they should be able to produce healthy, green foliage again within a few days.
