Frequently Asked Questions

My Bibb lettuce is developing pale, silvery patches and tiny black specks—could this be thrips, and what should I do?

Yes, thrips commonly cause silvery scarring and specks on lettuce leaves. Rinse plants with a strong spray of cool water, then apply insecticidal soap (especially under leaves) in the early morning and repeat every 5–7 days for at least 2 rounds. Remove badly infested leaves and keep weeds down, since thrips build up on nearby hosts.

How often should I water Bibb lettuce during the main growing phase?

During the main growth period, keep soil consistently moist but not waterlogged—aim for about 1 inch of water per week, split into 2–3 sessions if it’s hot or windy. Check by pushing a finger 1 inch into the soil: if it feels dry at that depth, water; if it stays cool and damp, hold off. Uneven moisture leads to bitter leaves and can trigger early bolting in Bibb.

When is Bibb lettuce ready to harvest, and how do I know?

Harvest when heads feel firm and leaves are full-sized—typically around 55 days from sowing for Bibb. Look for a compact, smooth head with outer leaves that are about 4–6 inches long; avoid waiting until leaves get loose or overly tall. For the best flavor, cut at the base early in the morning and chill right away.

Sink your spoon into Bibb’s velvety, butter-soft leaves—tender, sweet, and delicately nutty with a fresh, clean snap. Forming compact, spoon-shaped heads in about 55 days, this butterhead lettuce delivers a lush, pale-green heart cradled by gently cupped outer leaves. Ideal for fresh salads and elegant platters, Bibb shines when you want a tender texture that stays crisp and inviting from garden to table.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 32°F before moving outdoors. Harden off for 6 days first.

Expert Note

For Bibb (butterhead) lettuce, keep seedlings cool and transplant into consistently moist soil as soon as nights are reliably above freezing to avoid bolting.
