I am growing green and red romaine lettuce as well as a mesclun salad mix. I planted a bunch of seeds in each hole and now have a mound of leaves. Do I eventually thin the romaine to just one plant? What about the mesclun mix? The mesclun is a mix of ruby lettuce, Bull's Blood beet, Bloomsdale spinach, Simpson lettuce, and Tendergreen mustard.
Here is some pics:
