This July 1, 2013 photo shows a rooted softwood cutting in New Paltz, New York. Take a look at new shoots growing on a favorite shrub or vine and you'll see that the bases of these shoots may be beginning to toughen up, their once soft, green outer layer turning brown and woody. Such shoots, snipped from the mother plants as so-called half-woody cuttings, can be rooted to make new plants. (AP Photo/Lee Reich)
