I was just reading online that I'm supposed to thin lettuce?? Oops. How important is it to do this? The close up picture (picture 4) is of mixed lettuce and to me they look healthy, I don't want to thin them unless I definitely should? I also have a row of carrots that I need to thin but should I wait a bit longer? They are a few inches tall... I tried to take a few out already and re-plant, but the re-planted ones died. I hate thinning.
I also put a picture of the full garden, I realize the rows aren't the most thought out. We put bush bean seeds in the empty spaces, and they've started to come in. If there is anything else obvious that we did wrong, appreciated if you point out. Thank you!
