Last summer I planted a rosemary plant. It did wonderfully. At the end of fall I dug it up and put it in a planter and brought it in the house. It's still doing well. I plan on putting it back outside in the ground next month. My concern is that maybe I should purchase a new small plant. Does the taste change as the plant gets older? I'm not even sure if this is a valid question lol Thank you for your time. I appreciate it. BJ Lovett

So, the idea here, is that you want to grow the plant for new shoots. These will have the target flavor without being over bearing.
The trick here will be pruning. Some years you will want to prune down the older stems to about 6 inches to a foot, so that it can produce new usable shoots. Leave some of the new shoots, and they will be your new main branches, which you will cut in half for a year or two. They will then produce your new shoots.
You want to harvest the new growth of the plant so that you have growth for next year, bearing in mind that the growth that you leave will produce the year after that. Then you start the process over.
