Wax plant has moderate resistance to disease but is more vulnerable to high humidity and excessive watering. It also becomes more prone to illnesses if it receives little light and is overwatered. Regarding care, Wax plant tolerates drought and can go for extended periods without water. It requires minimal fertilizer and only occasional pruning. For these reasons it is appropriate for gardeners of any skill level, particularly those who prefer to spend less time on plant care or who may be away from home for extended stretches. It is a suitable option for people who do not want to invest much time in upkeep yet still want an easy-to-care-for plant.
How to keep Hoya Cordata.
Light
The wax plant generally flourishes in areas with moderate light, neither fully engulfed in shade nor directly exposed to sunlight. This corresponds to the conditions found in its natural habitats. Nevertheless, the wax plant has the ability to survive in environments ranging from total shade to complete direct sunlight, a factor that might influence its growth and overall health.
Water
The wax plant thrives in high humidity and benefits from a regular watering schedule of once every three weeks. It is ideally suited for indoor environments, thanks to its ability to retain water. As an evergreen, it maintains lush foliage throughout the year.
Temperature
The wax plant thrives best in a temperature span of 68 to 105 ℉ (20 to 41 ℃). It naturally grows in environments where warmth and humidity are abundant. To prevent harm from colder temperatures during winter, it is advised to maintain a warmth level between 60 to 85 ℉ (15 to 29 ℃).
Fertilizer
For the Wax plant, it is adequate to apply light amounts of fertilizer 1-2 instances annually during its growth phase. Refrain from fertilizing during winter and summer seasons when the plant is in a dormant state. After repotting, diminish the fertilizer amount for the plants and hold off on the fertilizing process for a few months. The act of fertilizing fosters robust growth and promotes flowering.
Pruning
Pruning a wax plant is typically unnecessary, as it naturally produces new leaves and flowers at the ends of its tendrils. However, if you need to manage its size or remove any dead growth, light trimming can be done. The best time for this is early spring, just as the plant is entering its growing season. Try to avoid pruning at other times to ensure the plant's health is not compromised.
Pot & Repot
When it comes to repotting the Wax plant, you should opt for a pot that's a bit larger than the current one, which has effective drainage. Make sure to use a cactus or succulent mix that drains well and is gritty. Carefully extract the plant from its previous pot, brush off any surplus soil, and then replant it at an equivalent depth. Allow a few days before watering the plant to give any injured roots time to recover. It's best to repot during spring or autumn and place the plant in a region with lots of light.

Reader questions.
What should I do if I give my Wax plant too much water or not enough water?
Wax plants are typically able to withstand periods without water, but if you neglect to water your plant for a month or more, it may show signs of underwatering such as a lackluster appearance, wrinkling, drying up, and brown or crispy leaves. To remedy this, submerge the pot in water for 5-10 minutes until the soil feels moist. On the other hand, overwatering is dangerous for wax plants and can lead to root rot. Symptoms of overwatering include yellow, swollen, and translucent organs that may burst open, browning or blackening of the plant, and falling leaves. To address overwatering, change the growing conditions by increasing air ventilation and adjusting the frequency of watering. To save an overwatered plant, remove it from the pot and examine the roots and soil. If root rot is present, the plant may not be salvageable. However, if only a portion of the roots are affected, the plant can potentially be saved. Remove unhealthy roots and dip the healthy roots in a fungicide before repotting in fresh soil. With proper care, the plant should recover and produce new growth.
Why is it necessary to fertilize my Wax plant?
Applying plant food to the growing medium of Wax plant helps provide essential nutrients for healthy growth. Although Wax plants already store water and nutrients, fertilizing during the growing season further supports their development. Additionally, fertilizing can stimulate mature Wax plants to produce blooms.
How much sunlight does Wax plant need to grow?
Wax plants can thrive in partial sun, but they need a good amount of light. Ideally, they should receive 3-6 hours of direct or indirect sunlight per day. The amount of sunlight required may vary depending on the specific species of Wax plant and their natural habitat.
What temperature is best for your Wax plant?
The Wax plant thrives best when kept in a specific range of conditions. Ideally, temperatures should stay between 75-90℉ (25-32℃). In the early winter, it's important to ensure that temperatures don't drop below 75℉ (25℃) for the Wax plant's well-being. If extreme temperatures are anticipated, it's advisable to bring the plant indoors for added protection. While the Wax plant can endure some extreme temperatures, it is not ideal for it. It can occasionally survive in lower temperatures around 50℉ (15℃), but it's still recommended to bring it indoors during winter conditions.
How much should I water my Wax plant?
To determine how often to water your Wax plant, there is no fixed rule. The best way is to check the soil and only water when it is completely dry. You can check by inserting your finger or using a moisture meter to test the soil below the surface. If you have planted it in a deep pot, you can also use a stick or chopstick. If the soil feels even slightly moist, wait a few days and check again. In general, most people will need to water their Wax plant every two weeks in the summer and once a month in the winter. However, there are various factors that can affect the frequency of watering. The section below provides some considerations to help you determine how often to water your Wax plant.
When should I fertilize my Wax plant?
Wax plants benefit from additional nutrients, but they only require a light dose of fertilizer during the growing season. It is recommended to fertilize them 1-2 times a year, specifically in the spring and autumn when they are active. Avoid fertilizing them in winter and summer when they are dormant. If you have recently repotted your Wax plant, be cautious with the amount of fertilizer you use. It is best to wait a few months after repotting before applying any fertilizer.
What will happen if the Wax plant doesn't receive enough sunlight?
Wax plants need sufficient sunlight to thrive. Without it, they can weaken and struggle to grow. If they don't get enough sunlight, they may develop leggy growth known as etiolation, and their leaves can become pale or discolored. In addition, a lack of sunlight makes wax plants more vulnerable to pests and diseases.
How do I change the temperature for my Wax plant as it grows?
The wax plant goes through different growing phases. First, the dormant seed develops into a seedling. To make this happen, the seeds have to be in the right conditions, with a temperature range of 75-90℉ (25-32℃) for germination. The best time for the wax plant to thrive is in the summer when temperatures are around 85℉ (30℃). During this time, it's helpful to move the plant from indoors to a sunny spot to ensure it gets enough sunlight.
What things should I think about when watering my Wax plant?
To properly water your Wax plant, there are several environmental factors to consider. These include the size of the container, the type of soil, the temperature, and the humidity. The container and soil will determine how often and how much water to use. Make sure the container has drainage holes so that excess water can escape. A small container holds less moisture, so it needs to be watered more frequently. On the other hand, a larger pot retains more water and requires less frequent watering. However, avoid using an oversized pot as this can cause overwatering. When repotting, choose a container that is only one size larger than the current one. Also, a shallow container is better than a deep one because Wax plants have shallow root systems. In terms of seasons, Wax plants need less water in winter and more water in the active growing seasons of spring and autumn. During winter, the plant has slower growth and requires less energy and water. Since evaporation is reduced in cooler temperatures, the soil remains wet for longer. It's important to note that the climate of your location also affects the watering needs of the Wax plant. In humid regions with frequent rainfall, watering will be less frequent compared to dry and arid climates. Keep in mind that the conditions can vary even within the same geographic location due to seasonal changes and indoor heating or air conditioning. For Wax plants planted in the ground, once they have established a root system, they typically won't need supplementary watering beyond precipitation and dew. However, during extended dry periods, occasional watering might be necessary. In areas where Wax plants can only be grown in containers, they can be moved outside during spring and summer when the temperatures are suitable and then brought back indoors when it starts to get cooler. Potted Wax plants kept outside generally require more water compared to those kept indoors due to increased sun exposure, even on a shaded porch.
When is it best to not fertilize my Wax plant?
The Wax plant, like other plants, goes into a dormancy period. During this time, it is important to avoid applying fertilizer. The plant stops growing in both summer and winter, so that's when you should stop fertilizing. Additionally, it is advisable to refrain from fertilizing for the first few months after repotting in the spring.
What happens if Wax plant gets too much sunlight?
To prevent sunburn and dehydration, it is crucial to monitor the amount of direct sunlight your Wax plant receives. Too much sunlight can lead to brown spots on the leaves or stems, and in extreme cases, the plant may wilt. Adjust the sunlight exposure as necessary to keep your plant healthy.
How do I make sure my Wax plant stays warm during the cold seasons?
To protect your Wax plant from harsh winter conditions, it is recommended to bring it indoors. Some people choose to purchase various types of grow lights to ensure the plant receives enough sunlight. However, if your home is not very dark, buying these lights is not necessary. Instead, place your plants in locations with the most sunlight possible, as this should be enough to keep the Wax plant thriving throughout winter. If you have multiple Wax plants, rotate their positions to ensure all of them receive sufficient sunlight. In northern areas with freezing weather, avoid placing the Wax plant too close to the window, as extreme cold temperatures may damage them.
