Something you may not realize about rosemary is that it is fairly easy to start from a cutting. From just a few of these you can have more rosemary for your own garden, some to share with friends or give away as gifts.
I have the shrub-like variety known as Rosmarinus officinalis It grows to a height of up 48" with a width of nearly the same. It is hardy for zones 7a-10b. Like most herbs, it prefers a drier well-drained soil. Rosemary that grew the largest at my house is planted on the south facing side of the house, where it gets plenty of sun.
Rosemary can be started by both seeds and cuttings, but cuttings have a higher rate of success and grow much faster.
Here is how to do it to propagate rosemary from cuttings:
|1. Cut branches from rosemary that are either semi-hardwood or softwood. (See the brown and white stems of each?)|
|2. Cut pieces about 5 inches long, stripping leaves off bottom 2/3|
