About Hoya plant
The Hoya plant, also called the wax plant, wax flower, Indian rope plant, porcelain plant or honey plant is a native plant of Australia, Asia and the Pacific islands. It belongs to the Apocynaceae (dogbane) family, according to recent taxonomy. It was initially in the Asclepiadaceae (milkweed) family.
The beautiful flowering plant grows in clusters with a ball or star or heart shape which shares striking semblance to the mophead hydrangeas with each bunch holding close to 50 single flowers closely wound together. The flowers appear perfect like they are made from wax or porcelain. Hence, the common names for the Hoya plants.
Hoya plants have evergreen, waxy leaves and woody stems and can grow as a vine or trail from a pot or hanging basket.
How to take care of your Hoya plant
Hoya plants are generally easy to care for with the right environment. They don't like it too cold and have other care requirements discussed below.
Watering Hoya plants
It is preferable to under-water your Hoya plant than to excessively water it because a wilt on this plant is easier to manage than root rot. The water used should also be at room temperature. You can achieve this by allowing the water in your watering can to sit for about 30 minutes before watering the Hoya plant. In Spring and Summer, between watering intervals, allow the first inch of soil to dry out. For other seasons, allow more drying out between watering. If you are trying to promote or force blooming really drying them out can help but once there are blooms be sure to not let it get totally dry otherwise the blooms will be the first to go.
Lighting needs of Hoya plants
Hoyas need a good balance or bright and indirect light to give optimal growth. The Hoya wax flower would still grow in low light conditions, but it may not produce ideal blooms in those conditions. Hoya plants grow best in dappled light or under a tree. If you are growing your hoya indoors, you can use LED light with a short wavelength.
Temperature needs of Hoya plants
As tropical plants, Hoya plants require temperatures of at least 60F to thrive. When the temperature outside is cold, keep the branches from stretching outside the window. As a rule, keep the plant entirely inside. If you prefer to grow your Hoya outdoors, you should consider transplanting them at the end of winter. Also, keep it away from direct contact with AC vents.
Humidity needs of Hoya plants
Hoyas are a tropical plant and do light higher levels of humidity. Mist your Hoya plant regularly to allow it to grow optimally. You can either use a humidifier or put the pot in a dish with water and pebbles. Hoya plants grow healthily in warm, humid environments similar in condition to their natural habitat so try to replicate these conditions and your Hoya plant will thank you for it with gorgeous blooms.
What is the best fertilizer for the Hoya plant?
Hoya plants thrive better with NPK (Nitrogen, Phosphorus and Potassium) fertilizers, according to the International Hoya Association. You should apply fertilizers with NPK monthly using a ratio of either 2-1-2 or 3-1-2. You can also use liquid fertilizers as needed for your Hoya variety, beginning application in spring and ending in autumn. We recommend monthly fertilizer applications in Spring and Summer, and every other month in the Fall and Winter months.
Soil needs of Hoya plants
Hoya plants need a soil that drains properly to allow for good aeration. You can make a suitable mix from equal portions of orchid and cactus mix with perlite.
