Why Your Shiso Plant Is Growing Sideways

Updated: June 30, 2023

Shiso, also known as Perilla, is a popular herb that is widely used in Asian cuisine. It has a unique flavor that is often described as a combination of mint and basil. Many people enjoy growing shiso in their gardens or even indoors as it adds a fresh and aromatic touch to dishes. However, you may have noticed that your shiso plant is growing sideways instead of upright. In this article, we will explore the reasons behind this phenomenon and provide some tips on how to fix it.

Insufficient Light

One of the most common reasons why shiso plants grow sideways is due to insufficient light. Shiso plants thrive in bright, indirect sunlight. If your plant is not receiving enough light, it will start to stretch towards the source of light, causing it to grow sideways.

To fix this issue, try moving your shiso plant to a location with more sunlight. A sunny windowsill or a spot near a south-facing window would be ideal. If growing indoors, consider using artificial grow lights to provide the necessary amount of light for your shiso plant to grow upright.

Improper Watering

Another factor that can cause shiso plants to grow sideways is improper watering. Overwatering or underwatering can both have negative effects on the growth of your plant.

Overwatering can lead to root rot and make the plant weak, causing it to droop or lean to one side. On the other hand, underwatering can cause the plant to become stressed and lose its ability to hold itself upright.

To prevent these issues, make sure you are watering your shiso plant correctly. Water the soil thoroughly when the top inch feels dry to the touch, but avoid letting the plant sit in waterlogged soil. It’s also important to use well-draining soil that allows excess water to flow out easily.

Lack of Support

Sometimes, shiso plants grow sideways simply because they lack proper support. As the plant grows taller, its stems become heavier, and without support, they can start to bend or lean to one side.

To avoid this, provide your shiso plant with some form of support. You can use stakes or a trellis to help keep the plant upright. As the plant grows, gently tie the stems to the support structure using soft plant ties or twine. This will encourage the plant to grow vertically instead of sideways.

Nutrient Deficiency

A nutrient deficiency can also be the culprit behind your shiso plant growing sideways. Shiso plants require a well-balanced diet of essential nutrients to grow properly. If any of these nutrients are lacking, it can affect the plant’s growth and cause it to become weak and droopy.

To rectify this issue, consider applying a balanced fertilizer specifically formulated for herbs. Look for a fertilizer that contains nitrogen, phosphorus, and potassium, as well as trace minerals like iron, magnesium, and calcium. Follow the instructions on the fertilizer packaging to ensure you are applying it correctly and in the right amounts.

Pests or Diseases

Lastly, pests or diseases can also cause your shiso plant to grow sideways. Insects like aphids or spider mites can infest the plant and weaken its structure. Diseases such as root rot or fungal infections can also affect the health of your shiso plant and cause it to lean or droop.

Inspect your shiso plant regularly for any signs of pests or diseases. If you notice any issues, take immediate action to treat them. Use organic insecticides or fungicides if necessary, but be sure to follow the instructions carefully to avoid harming your plant further.

Conclusion

If you find that your shiso plant is growing sideways instead of upright, it’s important to identify the underlying cause and take appropriate action. Whether it’s due to insufficient light, improper watering, lack of support, nutrient deficiency, or pests and diseases, addressing the issue promptly will help your shiso plant regain its upright growth and thrive in your garden or home.

Remember to provide adequate sunlight, water your plant correctly, provide support as needed, fertilize regularly, and monitor for any signs of pests or diseases. With proper care and attention, your shiso plant will soon be growing tall and straight, ready to enhance your culinary creations with its delightful flavor and aroma.
