Hoyas are a beautiful flowering plant that belongs to the genus Hoya, with the most popular being 'Hoya obovata'. Hoyas, semi-succulent epiphytic plants with thick, waxy leaves and long tendrils, are attractive trailing plants with drought-tolerant properties and easy care.

Native to Indonesia, the Hoya obovata, also known as the Wax Plant, is a stunning tropical vine that belongs to the Apocynaceae family.

The leaves of Hoya obovata are thick, fleshy, and oval-shaped, with a glossy, waxy texture. The leaves are typically a deep green color, but they can also have splashes of silver or cream variegation, which adds to their visual appeal.

One interesting characteristic of Hoya obovata is its ability to produce long, trailing vines. This makes it an excellent choice for hanging baskets or for training on a trellis. The vines can grow quite long, adding a touch of elegance and drama to any space. It is a fast-growing trailing succulent that can grow up to 20 feet long. 

When it comes to flowering, Hoya obovata produces clusters of small, fragrant flowers during spring and summer. The Hoya obovate flowers are star-shaped and typically have a creamy white or pale pink color. If your hoya blooms, leave the flower stalk alone; it will bloom again in a few years from the same stalk. These Hoya obovate blooms are not only beautiful to look at, but they also emit a lovely scent, making Hoya obovata a delightful addition to any indoor garden.

Watering Needs

When it comes to watering Hoya obovata, it's important to find the right balance. This Hoya plant prefers to be on the slightly drier side rather than constantly wet. Overwatering can lead to root rot and other issues, so it's best to let the top inch or so of soil dry out between waterings. 

To water your Hoya obovata, simply give it a good drink until water starts to come out of the drainage holes at the bottom of the pot. Then, allow the excess water to drain away. It's important not to let your succulent sit in standing water, as this can cause root rot. 

During the growing season, which is typically spring and summer, you can water your Hoya obovata more frequently. As the weather cools down in the fall and winter, you'll want to adjust your watering schedule and water less often. Remember that it is always preferable to be slightly underwater rather than overwater.

Keep an eye on the leaves of your Hoya obovata as well. If they start to look wrinkled or droopy, it's a sign that they are thirsty and need a drink. This type of soil allows excess water to drain away, preventing the roots from becoming soaked.

Light Requirements

Hoya obovata loves bright, indirect light for at least 4-6 hours daily. When growing indoors, it thrives in a spot where it can receive bright, filtered light throughout the day. Placing it near a north or south-facing window is ideal, as it will get plenty of light without being exposed to direct sunlight. 

When growing outdoors, direct sunlight can be too intense for Hoya obovata which may cause its leaves to burn or turn yellow. So, it's important to protect it from the harsh afternoon sun. If you don't have a suitable window with indirect light, you can also use sheer curtains or blinds to filter the light and create a more suitable environment for your plant.

If you notice that your Hoya obovata is not getting enough light, it may start to stretch or become leggy. On the other hand, if it's exposed to too much direct sunlight, its leaves may develop brown spots or become scorched. So, finding the right balance is key to keeping your Hoya obovata happy and healthy.

Remember to periodically rotate your plant to ensure that all sides receive equal amounts of light. This will help promote even growth and prevent it from leaning towards the light source. 

Optimal Soil & Fertilizer Needs

When it comes to soil, Hoya obovata prefers a well-draining mix. A combination of regular potting soil and perlite or orchid bark works well. This type of soil allows excess water to drain away, preventing the roots from sitting in soggy conditions. Instead, make or buy a well-draining potting mix, or ideally, use our specialized succulent potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your Hoya obovata succulent thrive.

As for fertilizing, Hoya obovata doesn't require a lot of nutrients. You can use a balanced (5-10-5), water-soluble NPK fertilizer specifically formulated for houseplants. During the growing season, which is typically spring, you can fertilize your Hoya obovata once a year. It's important not to over-fertilize your Hoya obovata, as this can lead to salt buildup in the soil, which can harm the succulent plant. 

If you notice that your Hoya obovata is growing well and producing new leaves, it's a good sign that it's happy with the soil and fertilizer you're providing. However, if growth is slow or the leaves are pale, it may be an indication that it needs a bit more nutrients. In that case, you can adjust your fertilizing schedule accordingly. 

Hardiness Zone & More

When grown indoors, Hoya obovata prefers temperatures between 60°F and 75°F. It can tolerate slightly cooler temperatures, but it's best to avoid extreme fluctuations or prolonged exposure to temperatures below 50°F. So, keeping your Hoya obovata in a cozy, warm spot in your home will make it quite content.

When growing outdoors, the Hoya obovata thrives in USDA zones 10 to 12. These zones generally have mild to warm temperatures year-round, which is ideal for this tropical plant. However, if you live in a colder climate, you can still enjoy Hoya obovata as a houseplant if you provide it with the appropriate indoor conditions.

In terms of humidity, Hoya obovatas, being epiphytic, requires humidity and misting but can thrive in regular household temperatures. Avoid placing them near fans, heat vents, or drafty windows to prevent extreme temperatures.

Remember, if you decide to transition your Hoya obovata outdoors during the warmer months, gradually acclimate it to the outdoor environment to prevent shock. Start by placing it in a shaded area, and gradually expose it to more sunlight over time. 

Hoya obovata Propagation

Propagating Hoya obovata can be a fun and rewarding way to expand your Hoya plant collection. One common method of propagation is through stem cuttings. Simply cut a healthy stem with a few leaves and place it in a well-draining soil mix or a glass of water. Keep the cutting in a warm and bright location, and roots should start to develop in a few weeks. Once the roots have grown, you can transfer the cutting into a pot with potting soil. 

Another method is propagating from leaf cuttings. Take a healthy leaf and make a diagonal cut at the base. Place the leaf-cutting in a well-drained soil mix and keep it slightly moist. With time, new shoots should emerge from the base of the leaf. Patience is key when propagating Hoya obovata, but with the right care and conditions, you can enjoy watching your new plants grow!
