Seaport goosefootChenopodium opulifoliumrepels pests
Spinach can deter pests that might otherwise target Seaport goosefoot.
What to plant with Spinach
Spinacia oleracea
Spinach grows best when paired with plants that repels pests, covers the ground, attracts pollinators. We've catalogued 16 beneficial companions and 4 antagonists to avoid. Every pairing below cites its mechanism — pest deterrence, nitrogen fixing, allelopathy, or shared disease.

16 plantsStrawberryFragaria × ananassacovers the ground
Spinach and strawberries form a cool, low-growing ground layer.
Allium cepaAllium ceparepels pests
Onions fit between spinach rows and help confuse aphids.
StrawberryFragaria × ananassacovers the ground
Low spreading plants suppress weeds, retain soil moisture, and shade out invaders.

White CloverTrifolium repenslives as mulch
Lower-confidence guild pairing: low ground covers protect soil, reduce bare patches, and can be cut back if they compete.
RadishRaphanus sativusacts as a trap crop
Lower-confidence guild pairing: trap crops can draw aphids or flea beetles away from the main crop when monitored and removed if overloaded.
NasturtiumTropaeolum majusacts as a trap crop
Lower-confidence guild pairing: trap crops can draw aphids or flea beetles away from the main crop when monitored and removed if overloaded.

Keep away from these they fight

Management warning: fennel is traditionally grown apart because it can inhibit neighbouring crops and disrupt guild balance.
Jerusalem artichokeHelianthus tuberosuscompetes for resources
Management warning: vigorous spreaders or allelopathic plants are best isolated from productive beds unless contained.

Management warning: vigorous spreaders or allelopathic plants are best isolated from productive beds unless contained.

Leafy greens can share cool-season beds if fertility is maintained.
IV
How these mechanisms work
pest repellent
Strong aromatics like basil, garlic, and marigold mask the olfactory cues that pests use to find their target crop.
ground cover
Low spreading plants suppress weeds, retain soil moisture, and shade out invaders.
pollinator attractor
Flowering herbs draw bees, hoverflies, and parasitic wasps — improving fruit set and biological pest control.
living mulch
A low-growing perennial covers bare soil under taller crops, reducing evaporation and weed pressure.
trap crop
A sacrificial crop draws pests away from the main harvest.

Frequently asked
What are the best companion plants for Spinach?
The top companions are Seaport goosefoot, Strawberry, Allium cepa. 13 more pairings are catalogued above with their mechanisms.
What should I NOT plant near Spinach?
Avoid Fennel, Jerusalem artichoke, Spearmint, and 1 other antagonists. Reasons vary — allelopathy, shared pests, or resource competition. See the section above for each plant's specific issue.
Can companion planting reduce pest damage on Spinach?
Aromatic companions deter many pests through scent masking and alarm pheromones. Effect varies by pest species and density — most effective as part of a polyculture, not a one-plant solution.
Is companion planting scientifically proven?
Some mechanisms are well-documented (legume nitrogen fixation, allelopathy in walnut and fennel, nematode suppression by marigolds). Others are traditional pairings with anecdotal support. We cite both, but mark mechanism strength where available.
