Introduction

Rattlesnake plants (Calathea lancifolia) are a popular choice for indoor plant enthusiasts due to their stunning foliage and low maintenance requirements. However, it can be frustrating when your rattlesnake plant starts growing sideways instead of upward. In this article, we will explore the reasons behind this common issue and provide solutions to help your rattlesnake plant grow upright.

Insufficient Light

One of the most common reasons why your rattlesnake plant may be growing sideways is insufficient light. Rattlesnake plants thrive in bright, indirect light conditions. If your plant is placed in a location with low light levels or is overshadowed by larger plants, it will naturally start to grow towards the available light source.

To fix this issue, consider relocating your rattlesnake plant to a spot that receives more indirect sunlight. Avoid placing it in direct sunlight as this can scorch the leaves. If moving the plant is not an option, you can also supplement the natural light with artificial grow lights. Position the lights above the plant to mimic the effect of overhead sunlight.

Improper Watering

Another common cause of sideways growth in rattlesnake plants is improper watering. These plants prefer consistently moist soil but are susceptible to root rot if overwatered. On the other hand, allowing the soil to dry out completely between waterings can lead to stress and uneven growth.

To ensure proper watering, keep an eye on the moisture level of the soil. Stick your finger about an inch into the soil – if it feels dry, it’s time to water your plant. Use room temperature water and ensure that excess water drains out from the bottom of the pot. Remember to empty any standing water from saucers or trays underneath the pot to prevent waterlogging.

Lack of Humidity

Rattlesnake plants are native to tropical regions and thrive in high humidity environments. When grown indoors, the dry air can cause the leaves to curl and dry out. In an attempt to seek more moisture, the plant may start growing sideways towards a more humid area.

To increase humidity levels around your rattlesnake plant, you can try a few methods. Grouping plants together can create a microclimate of increased humidity. Placing a tray of water near the plant or using a humidifier are also effective ways to raise humidity levels. For an extra boost, mist the leaves of your rattlesnake plant regularly with room temperature water.

Lack of Nutrients

Inadequate nutrition can also contribute to sideways growth in rattlesnake plants. These plants require regular feeding with a balanced houseplant fertilizer during the growing season (spring and summer). Without sufficient nutrients, the plant may grow weak and lean over to find more resources.

To ensure your rattlesnake plant has enough nutrients, fertilize it every 4-6 weeks during the active growing period. Use a diluted liquid fertilizer according to the package instructions. Avoid overfertilizing as this can lead to salt buildup in the soil, causing root damage.

Pests and Diseases

Pests and diseases can also affect the growth pattern of your rattlesnake plant. Spider mites, mealybugs, and aphids are common pests that can infest these plants and weaken their structure. Similarly, fungal diseases such as root rot and leaf spot can cause stress and hinder proper growth.

Inspect your rattlesnake plant regularly for signs of pests or diseases. If you notice any infestation or symptoms, take immediate action to control them. Remove affected leaves or areas of the plant and treat with an appropriate insecticide or fungicide. It’s important to follow the instructions carefully and repeat treatments if necessary.

Proper Plant Training

If your rattlesnake plant has already started growing sideways, you can help it regain an upright growth pattern through plant training techniques. Gently guide the stems and leaves towards the desired direction using stakes or plant supports. Be careful not to cause any damage to the plant while doing so.

Regularly check on the plant and adjust the supports as needed. As new growth emerges, ensure that it is directed upwards by gently manipulating its position. Over time, with consistent training, your rattlesnake plant will develop a more upright growth habit.

Conclusion

If your rattlesnake plant is growing sideways, it’s important to identify and address the underlying issues promptly. Insufficient light, improper watering, lack of humidity, lack of nutrients, pests, and diseases can all contribute to this problem. By providing the right conditions and care, you can help your rattlesnake plant grow upright and thrive in your indoor space. Remember to be patient and consistent in your efforts, and enjoy watching your plant regain its natural beauty.
