Did you know that there's a wealth of free plants right outside your own door? Many established plants can be divided and relocated to new locations within the yard; all at no cost or time spent driving to the garden center. And who wouldn't love that?
Dividing hostas is a great introduction to splitting plants for a variety of landscape designs. Spread your plants around to meet your needs, share a portion of the plant with a friend, or if you get several plants in your next purchased pot, you can divide the plants with this simple tutorial.
You can divide your hostas in either spring and fall. I personally like to do this task in the fall. Then the plant does not have a cut in half appearance for the next growth season as it might in the spring.
Here is how to split or divide hostas:
Dig up the plant you are planting to divide.
Shake any excess dirt from the roots.
Place the hosta on a firm surface or lay the plant down on the ground.
Using a straight spaded shovel, make your cut straight down the roots.
Now you are ready to plant your newly divided hostas. Make sure you place the plant at the same depth that they were prior to dividing. If you would like to add any compost to the soil, this is the time to do so. After you have planted your hosta, don't forget to water the new plant well. Watering also helps to remove air pockets and provides a much needed drink for your new plant.
Be aware that if you divide your hostas way back, you can set back the growth rate by a few years as you are disrupting the root system. So dividing should only be done every few years to keep your hostas healthy.
