Marry Your Flowers and Veggies: Companion Planting Guide to Your Garden


By Linda Ly

Gardeners know that a diverse mix of plants, from annuals and perennials to flowers and vegetables, makes for a healthier garden. But did you know that the right (or wrong) combination of certain plants could actually make them more (or less) productive? The process is known as companion planting, and it’s believed that growing these plants in close proximity may help deter pests, promote growth, and even improve flavor—or on the opposite end of the spectrum, stunt each other’s growth. Learn which flowers and veggies work well together, and which ones should be planted far from one another.

Tips for Watering Companion Plants

When growing different varieties of plants side by side, try to group them together by water needs. Deep-rooted vegetables like tomatoes and asparagus should be placed in the same bed, as they’ll thrive with less frequent (but more thorough) watering that soaks deep into the soil. On the flip side, shallow- to medium-rooted plants like beans and chard benefit from more frequent watering that saturates just the first few inches of soil. Wind soaker hoses around your plants and attach them to dual outlet electronic timers to easily manage your watering schedule for different beds.
