Transform your garden into a source of vibrant, farm-to-table freshness with non-GMO heirloom Red Torpedo Onion seeds from Sow Right Seeds. These unique sweet onions produce stunning, elongated bulbs with a rich red hue that brings both elegance and exceptional flavor to your backyard harvests. Well-suited for spring or fall planting, Red Torpedo Onions thrive with minimal effort to yield high-quality produce for salads, grilling, and gourmet culinary creations.

Direct sow seeds outdoors in full sun during early spring or fall, planting 1/2" deep into rich, well-draining soil. Space seeds or thin young seedlings to 4–6" apart to allow the elongated torpedo bulbs ample space to develop. Keep the soil consistently moist throughout the growing season and ensure the planting area remains weed-free, as onions have shallow root systems that compete poorly with weeds. Harvest when the top green foliage begins to yellow and fall over naturally, then cure the harvested bulbs in a dry, ventilated area before storing.

Frequently Asked Questions

Red Torpedo (also known as Tropea Red) is traditionally classified as an intermediate to short-day onion variety. This makes it particularly well-suited for warmer, southern regions and areas where day length stays moderate during the growing season.

Due to their high sugar and water content—which gives them their sweet, mild flavor—Red Torpedo Onions are generally considered sweet onions and have a shorter shelf life than pungent storage onions. They are best enjoyed fresh or cured for short-term storage (typically up to 2 to 3 months).

Yes! You can harvest immature plants early for fresh, tender green onions with a mild red tint and subtle onion flavor, or let them mature fully into elongated, sweet red bulbs.

Onions require full sun, steady moisture, and loose, nutrient-rich soil. Poor drainage, overcrowding, heavy weed competition, or planting at the wrong time for your region's day length can restrict bulb growth and result in smaller onions.
