Hi, I bought my mint plant about 2 weeks ago and it has grown A LOT. However, when I've researched online how and when to prune it, I've just been left confused or unsatisfied with the information. I do really well with pictures showing me how to do this kind of stuff but have been really unsuccessful finding something online that I've felt comfortable relying on for information. How should I prune it, where on the stem, and how often? What should it look like to tell me it's time?
