Hoya Obovata: Plant Care & Growing Guide 

Hoya are extremely popular houseplants and for good reason. These attractive climbing plants are characterized by thick, waxy leaves and long tendrils.

They make excellent hanging plants, but can also easily climb mossy posts and beams. Hoya are semi-succulent epiphytic plants, which means they naturally extract nutrients and moisture from the air, and their thick leaves retain water similar to succulents. This makes them drought tolerant and generally relatively easy to care for.

Hoya obovata is a unique variety of Hoya that is identified by its large deep green oval leaves that generally have a silver "dotted" pattern.

It is generally harder to find than the more common Hoya carnosa, but it is known to be a faster growing variety. Its unique appearance makes it sought after by collectors and beginners alike.

Hoya Obovata Care

Hoya obovata requires very little ongoing care and maintenance. They work best in bright, sunny windows and require frequent watering.

An important aspect of caring for soybeans is proper fertilization - these fast-growing foliage plants benefit from regular fertilization during the spring and summer months to keep their growth healthy and full.

Although soybeans are not normally grown for their flowers (and generally don't bloom until they are at least two or three years old), they are impressive and fragrant if you are lucky enough to see them.

If your hoya blooms, it is important not to leave the flower stem dead, as the hoya will bloom from the same stem again in the next two years.


Hoya obovates require constantly bright light to thrive. In their natural habitat, they grow among trees and receive bright, dappled light.

If grown outdoors, keep plants away from direct, strong rays as they can burn. However, if grown indoors, place your hoya obovata in the lightest spot you have. A sunny south-facing window is ideal.


Well-drained, aerated soil mixes are best for hoya obovata plants, as the roots require good drainage and aeration. A mixture of peat, perlite, and orchid bark is popular for holes as it provides adequate drainage and root space.

Alternatively, a mixture of potting soil, pumice stone, compost, and an orchid bark mixture is also appropriate.


Hoya obovatas are very sensitive to excess hydration and must dry completely between waterings. The frequency of watering hoya obovata depends on several factors, such as the amount of light it receives, the type of pot in which it is planted (plastic, ceramic, terracotta), the soil in which it grows, and the season.

Wait for the soil to dry out and water well. In the fall and winter months, reduce watering while the plant is dormant.

Temperature and Humidity

Because they are epiphytes, hoya obovata appreciate regular moisture and / or fogging. However, this is not a requirement and soy can normally thrive at regular temperatures and humidity levels in the home.

Avoid placing your hoya obovata too close to fans or vents / windows to ensure they are not exposed to extreme temperatures.


Hoya obovatas are fast growing plants that require regular fertilization during spring and summer to support their growth.

To stimulate foliage growth, use a high nitrogen fertilizer. If you notice that your soybeans are about to flower, switch to a high-phosphorus fertilizer to encourage vigorous flowering.

The holes should be fertilized about twice a month during spring and summer.

Is Hoya Obovata Toxic?

All species of hoya plants, including the hoya obovatas, are not toxic to humans and pets.

Propagating Hoya Obovata

Hoya are easy to propagate in soil and water. Simply take the seedlings of a healthy Hoya obovata plant, remove the lower leaves from the stem, and place the exposed nodes in the water or soil.

The knots can be found in the places where the leaves grow from the stem. If it is spreading in the ground, make sure the soil is kept moist until the new plant is established.

Potting and Repotting Hoya Obovata

Hoya obovata does not require regular transplantation and can tolerate slight rooting. In fact, soybean plants that stick to the roots are more likely to flourish. Transplanting your hoya obovata every two to three years should be sufficient.

These climbing plants fit well in a variety of different pots, but you need to make sure the pot has a drainage hole at the bottom to prevent waterlogged soil from rotting the roots.

Terracotta pots tend to be a popular choice for hoya obovata plants because the weight of the pot helps offset the weight of the plant as it matures, but any type of pot with adequate drainage is appropriate.

Common Pests/Diseases

Hoya are susceptible to a variety of common sap-sucking houseplant pests, including aphids, mealybugs, mealybugs, and spider mites. They are also susceptible to a disease called sooty mold, which grows on the sweet, sugary residue of the leaves.

The best way to avoid soot fungus on your hoya obovata is to clean the leaves regularly and make sure that the sap that drips onto the leaves does not stay there for long periods of time.
