10 Seeds to Start in April: Fast-Growing Varieties for Busy Gardeners

Want to taste the fruits of your labor in just a few weeks? Radishes are the perfect April starter—maturing in 3-4 weeks, they’re ideal for teaching beginners about planting timing while delivering crisp, peppery rewards. Their rapid growth makes them perfect for small spaces, including container gardens where you can grow them alongside herbs or lettuce.

Sow seeds ½ inch deep in well-draining soil, spacing them 1 inch apart in rows 12 inches apart. Keep the soil consistently moist but not soggy, and thin seedlings to 2 inches apart once they sprout. Varieties like 'Cherry Belle' or 'French Breakfast' are great choices for their reliable performance and sweet flavor. For continuous harvests, plant a new batch every 2 weeks until early summer.

Radishes are a confidence-booster for new gardeners—they prove that patience pays off, and their fast growth keeps motivation high. Plus, their vibrant colors and crisp texture make them a garden favorite that’s as rewarding to grow as it is to eat. 🌱

Tired of buying green onions from the store every week? Green onions (scallions) are one of the easiest plants to regrow from scraps, giving you fresh garnishes in just 7-10 days—no replanting required.

Simply place the white root end in a shallow container of water, keeping it in bright light. Once roots and new shoots appear, transplant into soil for a perpetual harvest. For even more convenience, direct-sow seeds in well-draining soil every 2-3 weeks from April onward. They thrive in full sun to partial shade and tolerate light frosts.

Varieties like 'Blue Lake' or 'Contender' are reliable choices, producing tender pods perfect for fresh eating or freezing.

Zucchini delivers the ultimate yield—one healthy plant can produce dozens of fruits—with the right early start. Unlike other fast growers, zucchini rewards patience with prolific harvests, making it a must-try for gardeners who love abundance.

Looking to add a splash of color and flavor to your garden—and your plate? Nasturtiums are the perfect two-for-one plant, offering both stunning blooms and edible leaves with a peppery kick. These cheerful annuals (or perennials in mild climates) thrive in April's cooler temperatures and self-seed generously, meaning fewer plants to buy each year.

Sow seeds ¼ inch deep in well-draining soil with 6-12 inches of spacing between plants, as they spread easily.

Craving fresh cilantro but tired of the bitter taste from store-bought bunches? Grow your own—this fast-growing herb delivers tender leaves in just 30-50 days, but the trick is timing. Unlike many herbs, cilantro bolts quickly when days lengthen, turning bitter and flowering. The secret? Sow seeds every 2 weeks from April onward for a continuous supply of fresh, flavorful leaves.
