Whether you're a beginner or seasoned gardener, Shiso cultivation offers a satisfying and flavorful experience.

Shiso, also known as Perilla, is an herbaceous plant prized for its aromatic leaves and culinary uses. Cultivating Shiso can be a rewarding endeavor, whether you're a seasoned gardener or someone with a green thumb looking to expand their repertoire of herbs. Here's a comprehensive guide on how to cultivate Shiso:

Understanding Shiso:

Varieties: There are two main types of Shiso—Green (Ao) and Red (Aka). The Green variety has bright green leaves, while the Red has purplish-red leaves. Both possess a unique flavor profile, with hints of mint, basil, and citrus.

Growing Conditions:

  1. Climate: Shiso thrives in warm climates but can also grow in temperate regions. It prefers full sun but can tolerate partial shade.
  2. Soil: Well-draining soil with good fertility is ideal. Ensure the soil pH ranges from slightly acidic to neutral.
  3. Watering: Shiso prefers consistent moisture. Water regularly, allowing the soil to dry slightly between waterings.
  4. Temperature: Shiso prefers moderate temperatures, ideally between 65-80°F (18-27°C).

Cultivation Steps:

1. Seed Starting:

  • Timing: Start seeds indoors 6-8 weeks before the last frost date in your area. Alternatively, sow seeds directly in the garden after the last frost.
  • Sowing: Plant seeds about ¼ inch deep in seed-starting trays or pots filled with potting mix. Keep the soil consistently moist.
  • Germination: Seeds usually germinate within 7-14 days. Once seedlings have a few sets of true leaves, thin them to provide adequate space for growth.

2. Transplanting:

  • Hardening Off: Before transplanting outdoors, acclimate seedlings to outdoor conditions gradually.
  • Spacing: Plant Shiso seedlings about 12-18 inches apart in the garden.
  • Transplanting: Choose a sunny or partially shaded location with well-draining soil. Ensure the soil is well-prepared by adding compost or organic matter.

3. Care and Maintenance:

  • Watering: Water consistently, aiming for even moisture without waterlogging.
  • Fertilization: Use a balanced fertilizer or organic compost periodically to support growth.
  • Mulching: Apply mulch around the plants to retain soil moisture and prevent weed growth.
  • Pruning: Pinch off flowers to encourage leaf growth. Regular harvesting also stimulates bushier growth.

4. Harvesting:

  • Timing: Begin harvesting leaves once the plant reaches a height of 6-8 inches. Continual harvesting encourages new growth.
  • Method: Harvest individual leaves or prune entire stems. The leaves can be used fresh or dried for later use.

5. Pests and Diseases:

  • Pests: Watch for aphids, spider mites, and caterpillars. Use organic pest control methods if necessary.
  • Diseases: Shiso is generally resistant to diseases but watch for fungal issues in excessively wet conditions.

6. Winter Care (In Colder Climates):

  • Harvesting: Before the first frost, harvest remaining leaves or consider bringing potted plants indoors.
  • Mulching: Mulch around the base of the plant to protect the roots from freezing temperatures.

Culinary Uses:

Shiso leaves are versatile and commonly used in various cuisines:

  • Japanese Cuisine: Often used as a garnish, in sushi, salads, tempura, and pickled dishes.
  • Korean Cuisine: Used in Kimchi and as a wrap for rice and meat.
  • Southeast Asian Cuisine: Added to salads, spring rolls, and stir-fries.
  • Herbal Tea: Shiso leaves can be used to make a fragrant and flavorful herbal tea.

Cultivating Shiso can be a delightful addition to your garden, offering not only a unique culinary experience but also the satisfaction of growing a versatile and flavorful herb. With proper care and attention to its growing requirements, you can enjoy fresh Shiso leaves to enhance the taste of your favorite dishes or explore its diverse culinary and medicinal uses.

Shiso, also known as Perilla or Japanese basil, is a flavorful and aromatic herb that is widely cultivated in various parts of Asia. With its unique taste that combines hints of mint, basil, and anise, Shiso has become a popular ingredient in Asian cuisines, particularly Japanese, Korean, and Vietnamese dishes. Cultivating Shiso can be a rewarding endeavor, whether you're a culinary enthusiast or a home gardener looking to expand your herb collection.

Types of Shiso:

There are two main varieties of Shiso:

  1. Green Shiso (Perilla frutescens var. crispa): This type has vibrant green leaves with serrated edges. It is commonly used in salads, sushi, and garnishes due to its refreshing taste.

  2. Red/Purple Shiso (Perilla frutescens var. purpurea): This variety features reddish-purple leaves and is often used for pickling, coloring food, or as a garnish in Japanese cuisine. It has a slightly stronger flavor compared to Green Shiso.


Climate and Soil:

  • Climate: Shiso thrives in warm, sunny climates but can also tolerate partial shade. It requires well-drained soil and prefers temperatures between 50°F to 86°F (10°C to 30°C).

  • Soil: A fertile, loamy soil with good drainage is ideal for cultivating Shiso. A slightly acidic to neutral pH level (around 6.0 to 7.0) is suitable.


  • Seeds: Shiso can be grown from seeds, which are usually sown directly into the soil after the last frost date in spring. Alternatively, they can be started indoors 4-6 weeks before the last frost and transplanted once the seedlings are established.

  • Spacing: Plant the seeds or seedlings about 12-18 inches apart to allow ample room for growth.

  • Care: Water the plants regularly, keeping the soil consistently moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weed growth. Regularly remove any weeds to prevent competition for nutrients.

  • Fertilization: Applying a balanced fertilizer once a month during the growing season can promote healthy growth.


  • Shiso leaves can typically be harvested 60-70 days after planting.
  • Harvesting can be done by snipping the leaves at the stem. Continual pruning encourages bushier growth.
  • For continuous harvest, pick the leaves regularly, but avoid harvesting more than one-third of the plant at a time to ensure its growth and vitality.

Common Uses:

  • Culinary Purposes: Shiso leaves can be used fresh as a garnish in salads, sushi, sashimi, and soups. They can also be pickled, used to wrap ingredients, or added to stir-fries for a unique flavor.

  • Medicinal Properties: In traditional medicine, Shiso is believed to have various health benefits, such as anti-inflammatory and antioxidant properties.
