FAQs

Why is my lettuce not crisp after harvest?
Harvest early in the morning and refrigerate soon after. Heat or late picking can reduce crispness.

Why are my lettuce plants rotting at the base?
Overwatering or poor drainage is the usual cause. Water only when the surface feels dry and avoid soaking the crown.

What spacing is best for iceberg lettuce in containers?
Keep 6–8 inches between plants. Crowded plants won’t form proper heads.

Can I grow iceberg lettuce in partial sun?
Yes — 4–5 hours of filtered or direct morning light is enough for leafy growth. Heads are usually ready in 50–70 days depending on temperature and sunlight.
