FAQ: fertilizing Lettuce

When should I fertilize Lettuce?

Follow the stage cards above (soil prep → planting → mid-season). Exact rates depend on soil tests and local packages — FAO notes below show how growers describe fertilization in different countries.

Can I copy NPK numbers from the notes?

Treat them as historical/field guidance, not a prescription for your plot. Units and products differ by country. Confirm with agricultural extension before applying.

非施肥处方。过量施肥浪费成本并可能污染水体。请咨询当地农技部门。
