The great thing with division of perennial is that you can get so many new little plants. Suppose you were doing a little long border garden; borders of perennials. A nice long mass planting is always good. Here's a perfect little example of one single little plant. It's got a nice little root system on it. To do that, I work with my hands. I don't really use a knife because at this point, I'm wanting to try to pull apart and break away more of the root stock so that I can plant it in other areas. Just be real gentle and kind of work it a little bit. I'm pulling apart. Now, here's another one that has an even better root system. You can see that there's multiple little hairs, multiple nice root stock. At this point, I also may take my scissors and actually trim it down a little bit even shorter just to help reduce more shock, but also to send more energy to my root system there. From this one section of plant here, you can see that you can get several other new plants, which is what's so fun about perennial garden. Here's another one. Keep going. Here's another little teeny-weeny baby one, which will live. As long as you water your plants and provide them with a good potting mix. Here's another little nice iris plant. Out of that one little clump, I managed to get 1, 2, 3, 4, 5, 6 new plants to plant in a nice border.
