I have never planted herbs from seeds before. I just planted basil, cilantro, and oregano about a week ago. I am silly and didn't read much into it other than what it said on the back of the seed package so I just put a little pile of seeds about 1/4 inch in the dirt. Well now my basil is popping up and WAY to many of them sprouted. I know I need to thin it out but just not sure when, how or how much to leave behind.
Here is a photo of one of the plots. I have them all planted in cinder blocks if that makes any difference.
