Nevada

Lettuce

55d to harvest

Crisp as cool morning air, Nevada forms a dense, upright Batavian head with a refreshing crunch and a clean, sweet-green flavor. Its leaves are richly textured—deeply quilted and pleasantly tender—holding their shape beautifully for salads and bright, leafy platters. Grow Nevada for a steady harvest of sturdy, garden-fresh leaves that stay crisp and flavorful well into the season.

Frequently Asked Questions

What pest or disease problem is most common on Lactuca sativa (lettuce) and how do I fix it?

Watch for lettuce downy mildew and aphids, which commonly show up in cool, damp weather or with poor airflow. For downy mildew, remove affected leaves immediately and avoid overhead watering; keep plants spaced and water only at the base. For aphids, blast them off with a strong jet of water, then apply insecticidal soap in the evening, repeating every 5–7 days until numbers drop.

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

During active leaf growth, keep soil consistently moist but not soggy—aim for evenly damp soil down to about 2–3 inches. In full sun, this usually means watering about 1–2 times per week, increasing to 2–3 times per week during hot spells. If leaves start tasting bitter or bolting begins, it’s often from heat stress and irregular moisture, so water on a steady schedule.

How can I tell when Lactuca sativa is ready to harvest?

Harvest when heads (if you’re growing a heading type) feel firm and reach the expected size, typically around 55 days from sowing. For leaf lettuce, pick outer leaves when they’re large enough to eat—about finger- to palm-sized—without removing the growing center. Lettuce ready for harvest should be crisp and tender; if leaves become tough and plants suddenly bolt (flower stalk visible), harvest immediately.
