Thank you!! It did rain for two days after I put it out then of course got cold!!! Lol I'll leave it in a little longer!I'm not 100% certain in this case, but in my experience with growing basil, this herb gets really unhappy, really fast when conditions aren't to it's liking. They are really sensitive to high moisture levels in the soil and cool temperatures - and they respond quickly in those conditions. It's hard to tell, but the soil looks a bit moist. Bottom watering with basil is the best way (keeping the top of the soil dry), at least until they are on the larger side. If they haven't been slowly accustomed to being outdoors after having been kept inside this will happen too. They really like warm and dry conditions and they shock easily. If you get them warm and dry again, they will perk back up and continue to grow.
