Sweetie Baby Romaine Lettuce Seeds – Sweetie Baby is a compact, heat-tolerant baby romaine with crisp, crunchy texture and a wonderfully sweet flavor. Growing 6 to 8 inches tall, it forms vase-shaped heads perfect for small space gardens or containers. Sow seeds in fertile, well-drained soil in full sun, about 1/4 inch deep and 1 inch apart. Thin seedlings to 5 inches apart for optimal growth. Sweetie Baby is slow to bolt, making it ideal for long-lasting harvests. For a continuous supply, sow every few weeks in spring and again in late summer for a fall crop. Keep soil moist, and enjoy crisp, tender heads in salads and sandwiches.
