Are you asking yourself "When to start growing your lettuce?" Well, you have come to the right place. The time to start sow obviously depends on where you are in the world. However, you can use weather and temperature as an indicator when it is the right time to plant your lettuce.
When you reach the fall, you can sow all types of lettuce at two-week intervals starting eight weeks before the first frost. If there's only one month left before the first frost is to arrive, you should only sow cold-tolerant butterheads and romaines a they are more resilient.
