I have 10-15 50cm tall lettuce basil plants hanging in large flower pots over my balcony. They are approx. 14 weeks old. I have for about 4 weeks now been cutting the tops of the plants or pinching whenever flowers have developed.
Assuming optimal environmental conditions, is there a limit to the amount of times I can continue to do this before the plant will die?
I am very happy with these plants and would like to produce and conserve seeds for next year but would like to delay this as long as possible.
