I brought my overwinters outside and everything is great except that I noticed on some plants that the stems were yellowing. Should I leave it alone or cut them? Some of them went all the way dead but just the top stem. My first time overwintering plants but it seems they are doing fine since there is new growth. Thanks in advance for any advice on the cause or is this normal?
