I've had this stupid carpal tunnel for at least 15 years, maybe even 20. I sleep in a brace and it never bothered me much. Now suddenly 3 fingertips (index, long, and ring fingers) are staying kind of numb and tingly all the time. Definitely time to address it.
Juli, if you cut back your perennials in fall you might find that you have a lot less weeds. Many of those "weeds" could well be volunteers from your flowers. You might also benefit from using that preemergent in both fall (soon!) and spring. Your mature seed heads are most likely dropping seeds now, unless you deadhead constantly. And those seeds can sprout now, over winter as seedlings, and return next spring.
Your flowers look beautiful!
