    Master gardener William Moss demonstrates how to divide perennials to double the number of plants you grow.

    William Moss: To plant perennials is a way to take your favorite plants, and get more of them, so basically you get more plants for free. And we're going to talk about how to do that today.

    The first one we're going to talk about is your rhizomes. Those are things iris, Solomon's-seal, Trilliums, other plants that kind of build out with these big thick roots and spread across the land.

    So, I am going to take my trowels. You want to push them down in between some rhizomes and there you got it. All right! Now, we've got the clumpers. Now, what you have to do is you have to come down and find where they grow from, where the clump is. So if I want more, I've got to make sure that I keep some growing points on top.

    So, once again take your trowel, just drive it straight into the plant, snap, pull them apart and now, I've got my first division.

    Last one; let's do a fibrous-rooted perennial. Here's an aster. You see the stems coming up on the aster. You see all these roots, all these fibrous roots just growing massively down here. If they get to be tough like it's going to be hard to tear that apart, then you just pull out to thrust your perennials.

    So, whether use-in fibrous-rooted perennials, rhizomes, or bunch-forming perennials, they're easy to divide, and a great way to add more plants to your garden for next season. Get out and grow!
