Potting soil does wear out. Pretty quickly in warmer areas. I replace
1/4 to 1/3 of the soil in my outdoor plants yearly. Just take a little soil out (do not throw away, add to manure or compost to refresh) and put in new soil or compost. Ever so often maybe every 4 to 5 years, I change out all the soil. Many blessings for your continued success!

Thanks for the tips. Turns out that's pretty much what I've started doing this year (but it's only been a year since we got the planters). Especially since I learned that potting soil isn't real dirt (Container Gardening for Dummies has been very helpful for me). The trumpet vines are gone (I had two of them in different containers). I hate to let go of a healthy plant, but when I learned that they are, at the very least, high maintenance, they got the heave-ho. Fortunately they were relatively young and not climbing on anything yet. I did first try to find a home for them on Craigslist, but had no takers.
