Growing onions near bell peppers is highly beneficial. Like chives, the scent of onions helps keep away pests that usually target bell peppers. As members of the allium family, onions have a growth habit similar to chives, so they won’t overshadow your bell peppers or compete for water. This makes onions an excellent companion for co-planting.

Spinach is a great companion for bell peppers. It produces saponins, natural compounds that repel various garden pests. Additionally, spinach is a low-growing plant that complements bell peppers well, allowing you to harvest more from a limited space without competing for resources. Planting spinach also helps retain soil moisture.

One interesting aspect of companion planting is that many crops that pair well in the kitchen thrive together in the garden. For example, basil is one of the best companion plants for bell peppers, and they also taste great together!

Basil is a leafy herb that enjoys the shady spots under taller bell peppers. In exchange for this shade, basil repels aphids and other bugs and attracts pollinating insects. Basil also helps to improve the flavor of bell peppers.

Nasturtiums
