Tomato plants should generally be spaced about 2 feet (24 inches) apart to ensure healthy growth and good air circulation, which helps prevent diseases
. The exact spacing depends on the type of tomato and the growing method:
- Determinate varieties (bushier, compact plants that produce fruit in a short period) can be spaced 12 to 24 inches apart, with rows about 4 feet apart
- Indeterminate varieties (vining plants that grow and produce fruit throughout the season) typically need more space:
- If staked, space them 18 to 24 inches apart in the row
* If grown in cages, space 2.5 to 3 feet apart
* If allowed to sprawl on the ground, leave 3 to 4 feet between plants and rows
For rows, a spacing of 3 to 5 feet is recommended depending on the plant size and support method to allow sunlight and airflow
. In summary, a good rule of thumb is:
Tomato Type| Plant Spacing| Row Spacing| Notes
---|---|---|---
Determinate| 12–24 inches (1–2 ft)| About 4 feet| Compact plants
Indeterminate (staked)| 18–24 inches (1.5–2 ft)| 3 feet or more| Requires
pruning for airflow
Indeterminate (caged)| 2.5–3 feet| 3 feet or more| Larger plants
Indeterminate (ground)| 3–4 feet| 3–4 feet| Sprawling growth, more space
needed
Proper spacing improves airflow, reduces disease risk, and promotes better fruit production
