Growing Microgreens Starter Guide

Growing Organic Green Shiso (Perilla) Microgreen Seeds

Soak Green Shiso seeds for 8 hours before planting to encourage more uniform germination. Spread approximately 12 g of seed evenly across a moistened 10-inch-by-20-inch tray filled with a quality microgreen growing mix. Because shiso benefits from light during germination, a thin topdressing of vermiculite is preferable to a solid tray cover. Place a weighted cover or dome over the tray for 4 to 5 days of blackout, then move to grow lights for 6 to 9 hours per day. Green Shiso is prone to damping off, so bottom-watering is strongly recommended throughout — keep moisture consistent but never let the tray sit in standing water.

Shiso microgreens develop more slowly than most common varieties, so plan for a 16 to 22-day growing window from sow to harvest. You may notice a distinct herbal fragrance as the trays develop — this is normal and a good sign. Harvest when the cotyledons are fully open and the first true leaves are just beginning to emerge, cutting just above the soil line. Store freshly cut shiso microgreens in a sealed container in the refrigerator, wrapped loosely in a paper towel to absorb excess moisture. They are best used within a week and are most flavorful when eaten as soon as possible after harvest.

Benefits of Organic Green Shiso (Perilla) Microgreens

Green Shiso microgreens pack an impressive nutritional profile into a small, delicate package. They are a rich source of vitamins A, C, and K, as well as calcium, iron, potassium, phosphorus, and fiber. Shiso also contains notable levels of Omega-3 (ALA) fatty acids and perillaldehyde, an essential oil compound with anti-inflammatory and antioxidant properties. Because microgreens are harvested early, their nutrients are highly concentrated relative to the mature plant — making even a small garnish a meaningful addition to the diet.

Culinary Tips

Green Shiso microgreens are best enjoyed raw, as heat quickly wilts their tender leaves and dulls their aroma. Use them as a finishing garnish on sushi, sashimi, or ramen, or toss them into cold noodle dishes, spring rolls, and fresh salads. They pair beautifully with citrus-dressed seafood and work equally well as a flavor-forward accent on rice bowls, wraps, or even fruit salads. For a simple introduction, try layering a small handful across a bowl of miso soup just before serving — the warmth releases their fragrance without cooking them down.

Tips From Our Gardeners

Green Shiso is one of the slower microgreens to come in, so resist the urge to rush it — give it the full blackout period and keep the moisture steady with bottom-watering. Growers who try to top-water often end up fighting mold before the tray is ready to harvest. Patience and good airflow are the two things that make this one work.
