Companion Planting Checker
Some crops genuinely help each other — legumes feed their neighbours, strong-scented herbs confuse pests, sprawling leaves shade out weeds. Others share a disease or a pest and should be kept well apart. Pick two to four crops and this checker shows every pairing with a verdict and the reason behind it, drawn from the pairings that turn up consistently in kitchen-garden practice.

Every pairing
- Tomato + BasilGood
- · Its scent confuses or repels the other crop's pests
- · A long-standing pairing that gardeners say improves flavour
- Tomato + PotatoAvoid
- · They share soil-borne diseases such as blight
- · Both are hit by the same pests, so infestations spread
- Basil + PotatoNeutral
- No strong interaction either way — plant them together as you like.
Figures are typical averages. Your cultivar, soil and microclimate will shift them, so treat the results as a starting point.
How it works
- 1
Choose between two and four crops you are thinking of planting together.
- 2
Every possible pair is looked up in the built-in dataset of well-documented good and bad combinations.
- 3
Pairs with no entry are shown as neutral — most crop combinations simply have no strong effect either way.
- 4
The overall verdict flags any clash, so a single bad pair is enough to send you back to the plan.
