How to Trim Rosemary Plants
1. Identify the right branches: Choose branches that are long, woody, and have sparse foliage. These branches are ideal for trimming as they encourage new growth.
2. Make clean cuts: Use sharp pruning shears or scissors to make clean, angled cuts on the branches. Avoid tearing or crushing the stems.
