Tomatoes + asparagus: Yes — plant them together.
- Verdict
- Good companions
- Evidence
- Traditional
- Pairs rated
- 41
The traditional claim runs both ways: tomatoes are said to deter asparagus beetle, asparagus's early season complements tomato's late one. Mechanism evidence is thin but the timing fit is real.
Layout: Tomatoes go in as asparagus harvest ends — same bed, staggered seasons.
Why
- ✓This is long-standing garden practice; the mechanism is plausible but hasn't been formally tested.
- ✓Companion planting tweaks the odds — spacing, rotation, and airflow still matter more than any pairing.
When this doesn't apply
- →If either plant has had disease problems in this spot before, rotation history outweighs the pairing benefit.
How this was calculated
- 1. Pairing lookupGood companions
Tomato × Asparagus: rated 'good' (traditional) in the GardenSays pairing table.
- 2. Evidence standard
Confidence labels: 'documented' = mechanism supported in extension/research literature; 'traditional' = long-standing practice with plausible mechanism but thin formal evidence.
