I was given a mint plant in a 5 gallon pot by some friends. It was nice and green when I got it but now it is turning yellow and starting to flower. What is making it turn yellow? As I live in N. Las Vegas and it's been very hot here already, I water it in the morning. It is on my deck which faces East and only gets the morning sun. Am I watering it too much? It seems if you miss watering potted plants here once, it will be dead tomorrow, but then I've been known to kill them with kindness!

Thanks!
