With plants, you can take cuttings of almost anything… even their roots! Many but not all plants are perfectly capable of sprouting from a piece of root… and if you didn’t know that, you’ve probably never dealt with quackgrass or horsetail or even dandelions, all plants perfectly willing to sprout from a small section of root left in the ground. When it comes to ornamental plants, a number of varieties, especially those that naturally produce offsets (suckers) a certain distance from the mother plant, will readily grow from root cuttings. Here’s how to do it:

Cut a rather fleshy root into sections of about 2 to 4 inches (5 to 10 cm) in length and place them on their side on top of a pot filled to 4/5ths of its height with soil. Now cover with about 1/2 to 1 inch (1 to 2 cm) of soil. Place in a moderately well lit spot, indoors or out, and keep the soil moist until sprouts appear, which can take from a few weeks to several months. Then plant out the babies in a nursery for the rest of the season.
Normally the plant will be big enough to hold its own in a flowerbed the following spring, at least in the case of perennials. For trees and shrubs, one or two additional years of cultivation in a nursery will probably be needed.
You can also do the same directly in the garden: just drop the root sections into a shallow hole (1/2 to 1 inch/1-2 cm deep), cover with soil and water.
It’s most logical to take root cuttings in the spring or autumn, when the plant is dormant, but if you have to move or divide a plant in summer, why not risk a try?
The Laidback Gardener Method

Here is an even easier way to multiply plants by root cuttings. Just cut straight down into the ground at the foot of a likely plant with a shovel. This inevitably will cut at least a few roots and so, a few weeks or months later, plants will emerge from the soil at the foot of the mother plant. All you have to do then is to dig them up and move them to the desired location.
