Frequently Asked Questions

How often should I water Lactuca sativa during the main growing phase?

During the 6–10 week growing period to harvest, keep the top 1–2 inches of soil evenly moist—lettuce needs consistent moisture to prevent bitterness and early bolting. Water deeply enough to reach that depth, typically every 1–3 days depending on heat and container vs. ground conditions. If leaves start to look limp then crisp up suddenly, you’re letting moisture swing too much; aim for steady moisture rather than light daily misting.

How do I know when my Lactuca sativa is ready to harvest at about 45 days?

Harvest when heads are firm for the type you’re growing and outer leaves are fully expanded, usually around 45 days from germination. For cut-and-come-again, pick outer mature leaves once they’re large enough to eat, leaving the center to keep producing. If the plant starts sending up a flowering stalk or the center becomes noticeably elongated, quality declines—harvest immediately.
