Clumping plants often require division for their own general health and well-being but one advantage of this practise is that you end up with more plants. This is by far one of the easier and most succesful ways to propagate plants.

To divide clumping perenials like agapanthus, clivia’s and even chives start by using two gardening forks like a pair of salad spoons under the base of the plant. You need to position these far enough below the base of the plant to ensure you don’t remove the leaves from the roots.
Lever the two forks against each other as you prise the rootball from the earth and are left with the complete plant out of the ground. Then, begin to divide the clump by finding foliage and roots that could appear to be a separate plant if they were to grow on their own. Using a sharp knife sever this possible smaller plant from the main clump while keeping as many roots as possible attached. Continue cutting these little plants away until the whole clump is divided.
When you’ve finished dividing the clump, plant out the cuttings in potting mix or back in the place where they were taken from. You might want to dust the roots with a fungicide prior to planting on to increase your chances of success.
