Right now my lettuce is at a turning point.
This one is beginning to produce seed. The one below is ready to eat.
If I remove all the mature leaves, it will grow more, and the pruning will prevent it from going to seed at least until it gets a little bit warmer.
Harvesting the whole plant makes no sense when you can get this sort of lettuce of a single plant once a week for months.
Eventually it will all go to seed. I will miss the salads, but it is nice having the seed to plant this year after year.
These lovely plants have been giving us lettuce for five months now. Soon however it will get to warm, and they will bolt despite my best efforts to keep them producing.
