Hoya carnosa, commonly known as the wax plant or porcelain flower, is a popular houseplant cherished for its beautiful, waxy leaves and fragrant flowers. However, if you’ve noticed that your Hoya carnosa plant is growing sideways instead of upright, you may be wondering what could be causing this unusual growth pattern. In this article, we will explore the potential reasons behind your plant’s sideways growth and discuss possible solutions to help it grow upright.

Insufficient Light

One of the most common reasons for a Hoya carnosa plant growing sideways is insufficient light. These plants are native to tropical regions and thrive in bright, indirect sunlight. When they don’t receive enough light, they will often grow towards the nearest light source, causing them to lean or bend sideways.

To rectify this issue, ensure that your Hoya carnosa plant is placed in a location with bright, indirect sunlight. This could be near a north or east-facing window where it can receive ample light without being exposed to direct sunlight, which can scorch the leaves.

Improper Support

Another reason for sideways growth in Hoya carnosa plants is the lack of proper support. These plants are epiphytic in nature, meaning they grow on other plants rather than in the soil. In their natural habitat, they cling onto trees and use their aerial roots to anchor themselves.

When grown indoors, it’s essential to provide appropriate support for your Hoya carnosa plant. A trellis or moss pole can be used to give the plant something to climb on and encourage upright growth. As the plant grows, gently guide its vines towards the support structure and secure them using soft ties or twist ties.

Uneven Watering

Inconsistent watering practices can also lead to sideways growth in Hoya carnosa plants. Overwatering or underwatering can cause stress to the plant, resulting in uneven growth patterns. When the roots are constantly saturated or excessively dry, the plant’s growth can become stunted or distorted.

To ensure proper growth, water your Hoya carnosa plant thoroughly when the top inch of soil feels dry to the touch. Allow any excess water to drain away, as standing water can lead to root rot. It’s also important to avoid letting the plant sit in a saucer of water for prolonged periods.

Lack of Nutrients

A lack of essential nutrients can hinder the growth and development of Hoya carnosa plants, causing them to grow sideways. These plants require a well-balanced fertilizer that provides them with the necessary nutrients for healthy growth.

To address this issue, give your Hoya carnosa plant a balanced liquid fertilizer once a month during the growing season (spring and summer). Be sure to follow the instructions on the fertilizer packaging to avoid overfeeding, which can damage the plant.

Inadequate Pruning

Inadequate pruning can contribute to sideways growth in Hoya carnosa plants. Without regular pruning, the plant may become leggy and top-heavy, causing it to bend or lean sideways. Pruning helps promote bushier growth and encourages the plant to grow upright.

When pruning your Hoya carnosa plant, use clean, sharp scissors or pruning shears to remove any leggy or unhealthy stems. Cut back just above a leaf node (the point where leaves emerge from the stem) to encourage new growth. Regular pruning will help maintain a more compact and upright form.

Conclusion

If your Hoya carnosa plant is growing sideways instead of upright, there are several potential reasons behind this unusual growth pattern. Insufficient light, improper support, uneven watering, lack of nutrients, and inadequate pruning can all contribute to sideways growth.

By addressing these issues and providing your Hoya carnosa plant with proper care, you can help it regain its upright growth habit. Remember to provide adequate light, support the plant with a trellis or moss pole, water it consistently, fertilize regularly, and prune when necessary. With the right care, your Hoya carnosa plant will thrive and display its stunning foliage and fragrant blooms in an upright position once again.
