Wilting Celery

[kyliecoyote]

Hey guys!
So I’ll preface this by saying I’m very new to gardening but have recently gotten really into plants and need some help/advice. I rooted a celery plant from a stalk from my refrigerator and it has grown a lot and seemed very happy until I decided to pot it. It was in water for a while and had formed a lot of roots so I figured it was ready, but as soon as I re-homed it and put it outside it immediately began to wilt. I’m not sure if perhaps I used the wrong soil, or maybe it’s too hot currently where I live? (Houston). Anyhow, any thoughts would be welcome!
Thanks
