Bibb

Bibb lettuce thrives when started indoors four to six weeks before your last spring frost, though direct sowing is equally effective for gardeners who prefer to sow seeds directly into garden beds two to three weeks before the frost date. Indoor-started seedlings develop more robust root systems and allow you to transplant uniform, vigorous plants that will produce those signature tender heads more reliably. If direct sowing, scatter seeds thinly across prepared beds since Bibb's compact growth habit means you'll need less space than you might expect for other lettuce varieties.

Space plants eight to ten inches apart, which accommodates Bibb's naturally small, dense heads that reach only six to twelve inches tall. Sow seeds at a depth of quarter-inch in rich, well-draining soil amended with compost or aged manure before planting. Bibb prefers slightly acidic soil with a pH between 6.0 and 7.0, and consistent organic matter helps retain the moisture this variety needs without becoming waterlogged.

Water consistently and deeply, providing one to one-and-a-half inches per week through rainfall or irrigation. Bibb is particularly sensitive to inconsistent moisture, which causes the tender inner leaves to develop tipburn—a browning condition that ruins the quality of this premium lettuce. Morning watering is essential to keep foliage dry and reduce fungal disease pressure. Feed with a balanced, nitrogen-rich fertilizer every two weeks once plants are established, as Bibb's delicate sweetness depends on steady nutrient availability without stress.

Slugs pose the most serious threat to Bibb lettuce, as they're drawn to the soft, tender leaves that make this variety prized. Hand-pick slugs in early morning hours, use copper tape barriers around beds, or apply iron phosphate-based baits. Aphids colonize the dense leaf clusters, so inspect the interior of forming heads weekly and spray with insecticidal soap if populations appear. Flea beetles create small shot-holes in young seedlings; use row covers until plants are four weeks old to prevent significant damage.

Downy mildew flourishes in the cool, moist conditions Bibb prefers, so ensure excellent air circulation by avoiding overcrowding despite the variety's compact size. Bottom rot and lettuce drop, both soil-borne diseases, develop in poorly drained or overly wet conditions. Never overhead water in afternoon hours, and consider drip irrigation to keep foliage completely dry.

Succession planting every two weeks from early spring through early summer ensures continuous harvests of young, tender heads at their prime. Bibb reaches maturity in fifty-five to sixty days, making frequent sowings practical for steady supply.

The most common mistake gardeners make with Bibb is harvesting too late. These heads are best harvested when loosely formed but still tender, rather than waiting for completely solid hearts. Harvest in early morning when leaves are crisp, cutting at soil level to preserve the delicate texture that defines this exceptional variety.
