[header] How to grow rosemary [title] Get a rosemary cutting. [step] Rosemary is easiest to grow from a cutting, rather than planting seeds. Visit a community garden and ask for a cutting, or ask a friend for a cutting of their plant. 
After you find a rosemary plant, clip off a few 4 inch pieces to propagate. The best time to do this is in the late spring, but if you live in a warmer climate, this can be done during early autumn as well.
