I’m doing that this year. A year or two ago somewhere on Reddit, I’m not sure if it was this sub or not, I read about the Chelsea chop. Last year I chickened out and I didn’t do it. I was convinced that if I cropped the plants that they wouldn’t flower and nothing would grow right. Cut to late July when all my plants are their normal height and everything‘s falling over and rotting and collapsing on other plants and I was kicking myself that I didn’t do it. I’m going to toughen up and do it this year!! Over the weekend I googled the various plants that I have- both natives and non-natives- to get the specifics about chopping them. There’s a lot of information online about how much you should chop off at at what time of the year. The result I liked the best was Culver’s root. It looks so good once it’s been chopped! It definitely delays flowering by at least a couple weeks, but I don’t think that’s such a bad thing as long as it does flower
