AmaryllidaceaeCan you plant eggplant and garlic together?
Yes. Eggplant and garlic grow well together. A shared bed gave about 25% more harvest than separate beds in one field trial, and growing them together kept pests down in a field trial.
Why eggplant and garlic work together
More harvest from the same bed. In one field trial, a bed with both crops gave about 25% more harvest than the same space split into a eggplant bed and a garlic bed.
Fewer pests. In a field trial, growing them together kept pests down.
Better soil and nutrient uptake. In a field trial, garlic improved the soil or nutrient uptake of eggplant.
Soil chemical property changes in eggplant/garlic relay intercropping systems under continuous cropping. (Wang M · 2014 · PloS one)

Harvest from the same space compares a bed with both crops against the same area split into single-crop beds, counting the harvest of both crops (the land equivalent ratio in yield trials).
