There is a catch, however. It will cost you a little time and effort - but not much. Plants, unlike most land animals, are capable of regeneration. Many plants are capable of regenerating their entire root systems from a single cutting. This would be comparable to cutting off your arm and regenerating another person who is identical to you.
Plants are truly amazing.
Now through August is a good time to take cuttings of your favorite plants. If you've seen plants in your neighbor's yard or out in the woods that you would like to have, please follow a few simple steps. First of all, if the desired plant belongs to neighbors, be sure to get their blessing first. Using a sharp knife or pruners cut off a 6-10 inch segment of this year's growth. Remove most of the leaves leaving only 4-6 of the uppermost leaves.
