Negi (Allium fistulosum)
Negi is an allium (related to onions and garlic) that is grown similarly to leeks and can reach unbelievably lengths when properly cultivated. Negi comes in two varietals, Negi W5 for cooler weather and Negi S8 for warmer weather. Each varietal can be direct seeded, but transplants are recommended. When growing Negi it's important to leave space between each plant as well as regularly piling up soil around the shank of the vegetable to promote growth and keep the shank hidden from the sun. Negi can be harvested when the shank reaches anywhere between 10-18 inches in length, once the fistulosum layers have formed together and tightened.

- Transplanting recommended. Sow 3 seeds per cell into a 128-cell tray.
- Fill cells evenly and fully with soil, shake gentle to settle. Do not press hard on the soil; heavy compaction may prevent germination.
- Sow seeds 1/4" deep and cover gently.
Pruning & Preparation
- Prune seedlings at 5" in length — cut to remove top 1" to stimulate more growth.
- If multiple seedlings per cell, gently separate prior to transplanting.
- Transplant to 2" spacing.
- Plant deep: transplant 4–6" deep into soil, so only the green part of the stalk is showing.
- Water generously once plants are established (3 times per week).
- Hilling: to establish the characteristic long white shank, the base of the plant cannot be exposed to sunlight. Bury plants repeatedly when shank is 3” above the soil.
- Harvest at 10–18" in length (depending on hilling) when fistulous layers form together and tighten.
- Mature stalks will feel dense, not spongy, when squeezed.
- Negi can hold in the soil for weeks after maturity, and can store for up to 8 weeks.
