Cultivate iceberg lettuce early in the year; you can sow the seeds outside as soon as the soil can be used. Water the soil before sowing and make sure the temperature does not exceed 20°C since this will have a negative effect on the growth. Lastly, harvest your lettuce as the leaves grow bigger, in order to avoid the soil getting too crowded.
If you want to harvest your iceberg lettuce early, you can pre-cultivate your seeds for 3-4 before replanting outside.
