Rosemary turning brown
Hi I have a 2+ year old rosemary plant. Occasionally it does this thing where On some stems the lower leaves start turning brown, Dying, and climbing up. Why does it Do this and how can I stop this from happening? The rest of the plant seems healthy in the third picture, and the first two pictures show the Issue. Thank you for any help.

This looks like a fungal problem, likely due to the plant being kept too wet.
Rosemary is native to dry, hot climates. Our wet weather this year has caused a good deal of disease issues on many types of plants.
We suggest you take off the mulch (which holds moisture) and let the pot dry out and keep it drier, and if you need to, move it to where it will get good airflow so leaves and stems don't stay wet for long periods of time.
You can prune out any diseased or dead material.
We agree that the plant looks good overall.
