About Planting to Rosette

What should you be doing during this time?

Select and apply herbicides at planting based on weed survey taken before planting.

Plant seeds or transplant lettuce into uniform beds to the proper depth with a precision planting system.

Check for stand uniformity and wilted plants, and inspect plants for pests and their damage; manage if needed according to Pest Management Guidelines.

Treat fields with a history of severe lettuce drop.

Cultivate as close to seed line as possible.

Use automated thinners or hand thin seedlings and hand weed.

Install drip tape if using drip irrigation.

Apply nitrogen fertilizer as needed based on results of a presidedress soil nitrate quick test (PDF) (PSNT).
