Frequently Asked Questions

How often should I water Cosmo Savoy during its main growing phase?

Keep the soil consistently moist during the 35–50 day growth window, aiming for evenly damp (not soggy) conditions. Water when the top 1 inch of soil feels dry; in hot part-sun spots this often means about 1–2 times per week, but increase frequency if leaves wilt in the afternoon. Because Lactuca sativa is shallow-rooted, avoid long dry spells followed by heavy watering.

How do I tell when Cosmo Savoy is ready to harvest?

Harvest when the rosette is fully sized and the outer leaves are crisp and well-colored, typically around 50 days from sowing. For leaf harvest, pick outer leaves anytime once they’re large enough to eat, but for best texture wait until plants are near full size so the heart is formed. If plants start to bolt (flower stalk), harvest promptly for best flavor.
