How to Save a Dying Shiso Plant

Updated: July 1, 2023

Shiso, also known as perilla or Japanese basil, is a popular herb widely used in Asian cuisine for its unique flavor and aroma. However, like any other plant, shiso plants can sometimes struggle and show signs of decline. If you notice your shiso plant looking unhealthy or dying, don’t despair! There are several steps you can take to revive and save your shiso plant. In this article, we will explore some effective strategies for rescuing a dying shiso plant and bringing it back to vibrant health.

1. Identify the Problem

The first step in saving a dying shiso plant is to identify the underlying issue causing its decline. There are various factors that can contribute to a shiso plant’s poor health, including inadequate watering, nutrient deficiencies, pests, diseases, or unfavorable environmental conditions.

Inspect the plant carefully to determine if there are any visible signs of pests or diseases. Look for discoloration, wilting leaves, or unusual spots. Additionally, consider the environmental conditions your plant is exposed to. Is it receiving enough sunlight? Is it too hot or too cold? Is it in a well-draining soil mix?

2. Adjust Watering Routine

One of the most common reasons for shiso plants’ decline is improper watering. Shiso plants prefer moist but well-drained soil. Overwatering can cause root rot and other fungal diseases, while underwatering leads to dehydration and wilting.

To save your dying shiso plant, make sure you water it adequately. Check the moisture level of the soil regularly by inserting your finger about an inch deep into the soil. If it feels dry, it’s time to water your plant. However, if it feels wet or soggy, hold off on watering until the soil dries out slightly.

3. Provide Nutrients

Another factor that can contribute to a dying shiso plant is nutrient deficiencies. Shiso plants require a well-balanced fertilizer to thrive. If your plant’s leaves are turning yellow or showing signs of stunted growth, it may be lacking essential nutrients.

To provide your shiso plant with the necessary nutrients, consider using a balanced, water-soluble fertilizer. Follow the instructions on the package for the correct dosage and frequency of application. Be cautious not to over-fertilize, as this can lead to nutrient burn and further damage the plant.

4. Control Pests and Diseases

Pests and diseases can weaken a shiso plant and cause it to wither away. Common pests that attack shiso plants include aphids, spider mites, and whiteflies. These tiny creatures feed on the plant’s sap, causing wilting, yellowing leaves, and distorted growth.

To control pests, you can use organic insecticidal soaps or neem oil sprays. Thoroughly spray both sides of the leaves, ensuring you cover all affected areas. Repeat the treatment every few days until the pests are eliminated.

In case your shiso plant shows signs of diseases such as powdery mildew or root rot, it’s crucial to address these issues promptly. Remove any infected parts of the plant, improve air circulation around the plant, and avoid overwatering to prevent fungal growth.

5. Provide Adequate Sunlight

Shiso plants thrive in full sunlight or partial shade, depending on your climate. Lack of sunlight can cause weak growth and leggy stems, whereas excessive exposure to direct sunlight can scorch the leaves.

Observe your shiso plant’s location and ensure it is receiving adequate sunlight throughout the day. If necessary, relocate the plant to a spot where it can receive the right amount of sunlight for optimal growth.

6. Repot if Necessary

If your shiso plant is in a container and has been struggling for a long time, it may benefit from repotting. Over time, the soil in the pot can become compacted, leading to poor drainage and nutrient deficiencies.

Choose a pot that is slightly larger than the current one, ensuring it has drainage holes at the bottom. Gently remove the plant from its old pot, loosen the root ball, and place it into the new container with fresh potting mix. Water thoroughly after repotting to help the plant settle into its new home.

Conclusion

With proper care and attention, you can revive a dying shiso plant and restore it to its former glory. By identifying the problem, adjusting watering routines, providing nutrients, controlling pests and diseases, ensuring adequate sunlight, and repotting if necessary, you can save your shiso plant from further decline. Remember to be patient and consistent in your efforts, and soon enough, your shiso plant will thrive once again, providing you with fresh leaves packed with flavor for your culinary creations.
