Marigolds
Marigolds (Tagetes spp.), native to Mexico and Central America, are renowned for their vibrant golden and orange hues that seem to glow even under blazing summer sun. Sow seeds directly in June or transplant nursery-grown seedlings, spacing them 8–12 inches apart in full sun and fertile, well-draining soil. These hardy annuals handle high temperatures and poor soils better than many others—one of my go-to recommendations when summer seems hotter than usual! Their compact form and abundant blooms also make them a favorite for edging borders or filling container gardens.
Beyond their cheerful appearance, marigolds exude a pungent aroma—especially French marigolds (Tagetes patula)—that repels many insect pests, including nematodes that harm root vegetables. However, Japanese beetles (Popillia japonica), invasive in parts of North America, are actually attracted to certain marigold varieties; if you notice large beetle congregations, remove those plants or deadhead frequently to reduce infestation. On the beneficial side, marigolds draw hoverflies and parasitic wasps that prey on aphids and caterpillars. By June, expect non-stop blooms that last until the first frost, offering continuous color and natural pest management in your flower beds!
