Plant bush beans alongside chard rows. Both tolerate partial shade.

GarlicAllium sativum
BeneficialPest SuppressionSupported
Garlic allyl sulfide compounds deter leaf miners (Liriomyza spp.) and aphids that commonly attack Swiss chard. Garlic antifungal properties may reduce Cercospora leaf spot pressure.
Interplant garlic among chard or use garlic as a border planting.
