Your 8×4 ft garden plot fits 30 cilantro plants at 9-inch spacing.
- Between plants
- 9 in
- Rows
- 3 @ 15 in
- Total plants
- 30
Cilantro plants need 7-10 inches between plants, in rows 12-18 inches apart so you can walk between them. At the 9-inch midpoint, that's 10 per row and 3 rows — 30 plants.

Why
Crowding is the most common spacing mistake: closer planting doesn't add yield, it adds shade, disease pressure, and small fruit. When in doubt, use the wider end of the range.
- Air circulation between mature plants is the cheapest disease prevention there is.
- Roots spread wider than the plant looks in June — spacing is set for August size.
When this doesn't apply
- Compact cilantro plants can take the tight end of the range; large or vigorous ones want the wide end.
- Square-foot gardening compresses further than these numbers — it trades yield per plant for yield per bed and needs diligent feeding.
