To coax their best performance, plant tubers in well-draining soil after your last frost date (typically mid-May in most zones) and stake them early—these tall, architectural plants can reach 5 feet without support. Deadhead spent blooms religiously to encourage nonstop production, and fertilize monthly with a balanced bloom booster for those showstopping, cut-flower-worthy stems that last 7-10 days in vases.

Want a low-maintenance way to keep pests away while adding bold color to your garden? Marigolds are the answer—these cheerful blooms double as natural pest repellents, warding off nematodes, aphids, and even rabbits with their strong scent.

Plant French marigolds (compact and bright) or African marigolds (taller with larger blooms) in full sun for the best results. They thrive in well-draining soil and bloom continuously from May through fall, making them ideal for container gardens or sunny borders.

Transform a blank fence or arbor into a fragrant, living tapestry with sweet peas—the ultimate vertical garden star. These delicate climbers produce clusters of pastel pink, purple, or white blooms that fill May gardens with a sweet, intoxicating scent, perfect for romantic garden corners.

Sweet peas thrive in cool spring weather and need a sturdy trellis, fence, or even a simple wire frame to climb. Plant seeds directly in the garden after the last frost, spacing them 4-6 inches apart in well-draining soil with partial shade to prevent wilting. Deadhead spent blooms regularly to encourage continuous flowering, and watch as vines twine effortlessly upward, creating a lush, fragrant curtain.

Perfect for small spaces or urban balconies, sweet peas are ideal for gardeners who want instant vertical impact without the fuss of heavy shrubs or sprawling vines. Their old-fashioned charm makes them a favorite for cottage gardens, but their easy care makes them accessible for beginners too. 🌷
