How to Grow and Care for Hoya Plant
Hoyas or wax plants can be described as a Asian native plant that is fragranced, low-maintenance tropical blooms which grow in a ball-shaped cluster. The low-maintenance plants have branches with woody stems and waxy leaves that remain evergreen.
It is possible to train hoya plants to be a vine or let it follow. Whatever you choose, anticipate the length and size of your plant to be between 2 to four feet. Hoyas require direct, bright sunlight for up to 6 hours per day. They also require well-drained soil that is moist and well-drained. It will dry between irrigations.

Hoya Care
Here are the primary needs for hoyas that grow:
- Plant out in spring or the beginning of summer in a location that receives bright indirect light.
- Set your hoya plant into an ornamental hanging basket, or allow it to hang to a small trellis creating a vertical focal point in your tropical garden.
- Provide the plant with humid conditions. This could be done by placing it next to an pond, fountain or any other water-based features.
- The best soil for this is moderately moist, well-drained soil. Allow it to dry between irrigations.
- Apply a balanced, slow-release fertilizer at least once a month.
Light
Hoyas thrive when they receive direct, bright sunlight for minimum two to six hours a day.
Soil
Hoyas prefer to be placed in a well-draining and light soil mix that has an acidic pH (6.1-7.5).
Water
Hoyas need to be watered regularly and allowed to completely dry between waterings. If they receive too many gallons of water they will begin to rot.
Temperature and Humidity
As a tropical plant hoyas thrive in humid and warm humid climates. A typical room temperature is ideal for these plants. However, it is possible that you will need to increase humidity. You could consider using a humidifier, or putting your hoya in an area that is humid like the bathroom, provided there is sufficient lighting.
Fertilizer
Hoyas need to be fertilized every month The International Hoya Association suggests feeding the plants with fertilizers that contains nitrogen, phosphorus, as well as potassium.
Types of Hoya Plants
Hoya is an Asian native plant, introduced through Scottish botanist Robert Brown and named in honour of the botanist from 18th century Thomas Hoy.
H. carnosa Flowers of light pink with dark green leaves that follow.
H. archboldiana cup-shaped cream flowers with an orange corona.
H. compacta “Indian Rope” Pink flowers with pale curly leaves. Beautiful even when it’s not flowering.
H. cumingiata Flowers of yellow with a red corona; aromatic.
H. kerrii variegata ‘Sweetheart Plant’: Heart-shaped leaves with white margins, flowers of orange and yellow.
H. onychoides: Flowers in purple with an exaggerated star-shaped shape.
H. australis: Round oval-shaped leaves with long climbing vines and fragrant white flowers.
Pruning
Hoyas can be considered slow- to moderately-growing. If your hoya plant has finished blooming, remove the flower stalk in place, since it could create new blooms. By removing the stalk, you force the plant to grow a new stalk. This causes delays in blooming and wastes its energy. Hoyas can be light eaters and a daily drinking made of compost tea, or dilute fish emulsion gives all the nutrients tropical plants require.
Propagating Hoya
- Hoya plants can be propagated by cutting off stems and then establishing the plants in water or soil. They require nothing more than the well-drained soil and humid, warm climate that the majority of tropical flowers desire.
- Hoya can be grown outdoors if you live within USDA zones 10-12. otherwise, you can grow it as a greenhouse plant or container. Pick a spot that receives the sun’s full or partial. Plants that get less than half a day of sunshine may not bloom. Here’s how to reproduce them using cuttings:
- Pruners are required, as well as the hormone that helps root (optional) as well as the soil for potting Hand shovel and a clean container.
- Cut a 4-inch piece of softwood. Cut it along a diagonal that has at least two leaves on the top. The cutting should contain at least two points for roots to sprout from.
- You can place the cut end into the mixture of rooting hormones. Put the cut end in a glass filled with filtered water. Within 4 weeks of soaking, the roots will be visible.
- The roots should be planted in a moistened potting mix, and then place them in a place that receives at minimum six hours of sun.
How to Grow Hoya Plants From Seed
Seeds can be planted in flats or pots. Here’s how to reproduce using fresh or harvested seeds:
- You’ll require a high-quality soilless potting mix that is enriched with pumice or perlite, an potting container or flat, as well as an unbreakable plastic bag.
- Make holes that are inch-deep in the potting mix. Place one seed in each hole, then top it off with a light layer of the potting mix.
- The soil should be lightly moistened and then place the tray in an airtight bag to provide the plant a humid like a greenhouse.
- The seeds are expected to germinate within 7-10 days.
- When the plant has developed real leaves after around one year of development, you can repot it.
Potting and Repotting Hoya
Hoyas love the safety of a pot that is snug, or plants roots-bound will bloom more frequently than those that are in a huge pot. Hoyas do not like feet that are wet or a heavy soil. They can be found as epiphytes in the natural world (similar to orchids and bromeliads). Mix regular potting soil with orchid pots in a 1-1 ratio to create the perfect habitat for your orchid plant.
When making a repotting attempt, use pasteurized dirt or a medium for growing in new pots, or those that have been cleaned with a bleach solution containing chlorine and water.
Overwintering
Hoya plants are able to withstand cold winters in the zones of 10 degrees and higher with no special care for winter. In cooler climates hoyas should only be planted outdoors in summer and spring when nighttime temperatures are over 50 degrees.
Common Pests and Diseases
Hoyas are susceptible to sap-sucking insects such as mealybugs and aphids as well as spider mites. The solution is Neem oil. After you’ve treated the plant, clean away the pest remnants with the use of a soft, clean cloth.
Fungal infections are likewise common illnesses of the hoya. Botrytis blight may cause rot and even kill the plant. It shows in the form of grey patches. Treatment is with fungicide and then repot the plant in a sterilized potting media.
How to Get Hoyas to Bloom
Hoyas are reliable bloomers in warm weather however, they require the correct soil, plenty of sunlight, sufficient humidity and water, as well as nutrients. Fertilizers with higher levels of phosphorus tend to increase the bloom. It could take up to seven years before reaching maturity and flower.
Bloom Months
Hoyas can flower in June until September.
How Long Do Hoya Plants Bloom?
Hoya flowers can last for around one week.
What Do Hoya Flowers Look and Smell Like?
Hoya flowers are arranged in a ball-shaped group or umbrel similar to mophead Hydrangeas. Each cluster could include up to 40 separate flowers that are tightly packed together. The individual flowers appear like they were made from porcelain or wax, hence their popular names. Flowers usually sport eyes that are colored within the corona. Flowers have a sweet scent, which ranges between citrus and vanilla.
How to Encourage More Blooms
To ensure that the plant is able to produce more flowers To encourage more blooms, make sure the soil drains well, the plant gets at minimum six hours of sunlight and is moderately moist and is protected from diseases and insects. Additionally, ensure that the plant is in its root, as this will increase the production of flowers.
Deadheading Hoya Flowers
Never deadhead hoya flowers. The cutting off of the spurs, where the flowers blossom is damaging the flowering portion of the plant. As a result, it won’t flower again next year.
Common Problems With Hoya Plants
The Hoya plant is a tropical and re-creating their ideal conditions is difficult. Most of the problems stem due to not having their environment in the right way.
Leaf Drop, Leaf Blackening, Stem Dieback
Overwatering can be among the main issues that can lead to root rot. In addition, not providing the right temperature could be equally troublesome. All of these issues could cause a plant in its shed leaves suffer from leaf becoming black or appear to be dying. In addition, overwatering can cause leaves to become yellow and drop. You can save or revive the dying plant by changing the humidity, water, and temperature.
Wilting
The overwatering of plants can cause wilting however, as can excessive fertilizer, which makes the roots ineffective at absorbing water. If your plant is prone to excessive salts in your soil, wash it down with water to remove them thoroughly. Do not give fertilizer. Instead after a month or so, you can give compost tea or top dressing.
Lanky, Straggly Growth
If your plant starts to appear stringy is it possible that it’s not getting sufficient light, and it’s searching for more. Plants extend out to seek more light. Plants should be moved closer to a brighter light source or, if you are growing in a dark room, provide your plant with an LED grow light.
