How to Grow Shiso Plant Indoors

Shiso, also known as Perilla, is a popular herb in Asian cuisine. With its distinct flavor and vibrant colors, it adds a unique touch to various dishes. While shiso is commonly grown outdoors, it is also possible to cultivate it indoors, allowing you to enjoy this flavorful herb all year round. In this article, we will guide you on how to successfully grow shiso plants indoors.

Choosing the Right Variety

Before you begin growing shiso indoors, it is important to choose the right variety for your needs. There are two main types of shiso: green and red. Green shiso has a mild flavor with hints of cinnamon and clove, while red shiso has a stronger taste with notes of mint and basil. Consider your culinary preferences when selecting the variety.

Starting from Seeds or Seedlings

Once you have chosen the variety, you can start growing shiso from either seeds or seedlings. If you decide to start from seeds, soak them in warm water for 24 hours before planting. This process helps to soften the seed coat and improve germination rates.

Fill a seed tray or small pots with well-draining potting soil. Place the soaked seeds on the surface and lightly cover them with a thin layer of soil. Keep the soil consistently moist but not waterlogged. It is recommended to cover the tray or pots with plastic wrap or a clear lid to create a greenhouse effect and promote germination.

If you prefer to start with seedlings, you can purchase young shiso plants from a nursery or garden center. This option allows you to skip the germination stage and jump straight into caring for established plants.

Providing Optimal Growing Conditions

Shiso plants thrive in warm conditions with plenty of sunlight. Choose a sunny spot in your home where the plants can receive at least 6-8 hours of direct sunlight each day. If natural sunlight is limited, you can supplement it with fluorescent grow lights placed 6-12 inches above the plants.

Maintain a temperature range of 65-75°F (18-24°C) for optimal growth. Shiso plants prefer slightly humid environments, so consider using a humidifier or placing a tray filled with water near the plants to increase humidity levels.

Watering and Fertilizing

Proper watering is crucial for shiso plants. Keep the soil consistently moist, but avoid overwatering as it can lead to root rot. Allow the top inch of soil to dry out before watering again. It is recommended to use room temperature water to prevent shocking the plants.

Fertilize shiso plants every two weeks during the growing season with a balanced liquid fertilizer. This provides them with essential nutrients for healthy growth. Be sure to follow the instructions on the fertilizer package for proper dilution ratios.

Pruning and Harvesting

Regular pruning helps maintain the shape and encourages bushier growth in shiso plants. Pinch off the tips of the branches to promote branching and prevent legginess. You can also remove any yellow or dead leaves to keep the plant looking tidy.

Shiso leaves can be harvested once the plant reaches a height of 6-8 inches. Harvesting can be done by simply snipping off individual leaves or cutting entire stems, depending on your culinary needs. Avoid harvesting more than one-third of the plant at a time to ensure its continued growth and productivity.

Pests and Diseases

While shiso plants are generally resistant to pests and diseases, they can still be susceptible to certain issues. Keep an eye out for aphids, spider mites, and whiteflies, which are common pests that may affect shiso plants. Regularly inspect the leaves and stems for any signs of infestation and treat them accordingly using organic insecticidal soap or neem oil.

Culinary Uses

Now that you have successfully grown your shiso plants indoors, it’s time to enjoy their culinary benefits. Shiso leaves can be used fresh or dried in a variety of dishes. They add a flavorful twist to salads, sushi rolls, stir-fries, and even cocktails.

Green shiso leaves are commonly used in tempura or as a garnish, while red shiso leaves are often pickled or used to wrap sushi. The seeds of shiso plants can also be harvested and used as a spice or seasoning.

Conclusion

Growing shiso plants indoors allows you to enjoy this versatile herb all year round. With the right variety, optimal growing conditions, and proper care, you can have a constant supply of fresh shiso leaves for your culinary creations. So why not give it a try and elevate your dishes with the unique flavors of shiso?
