My rosemary has been neglected and is much too large. It has split into two branches about 30 cm from the ground. The main branch (which I would like to remove) is about 28cm in circumference, and the other is about 21cm. Could I cut off the main branch and retain the other? If so, what time of year is best, and are there any precautions to take?

I think I would take some cuttings as well, then if the mother plant looks unsightly you'll have some new plants to replace it with.

Thank you both for your advice. I will take a "belt and braces" approach by following both suggestions!

yes you can cut it out, now or in the spring. give the foliage a light trim to encourage new busy growth.
