Why Do You Split Hostas

If your hostas aren’t growing or are starting to die at the center of their clump, you may want to consider dividing them. However, this isn’t necessary for all hostas.

Rather, split your hostas only when you see a bare spot or if the plant’s center clump is getting too large and causing crown rot. Dividing sooner, however, can do more harm than good.

What to Expect

Hostas are a popular perennial garden plant that grow well in shade and offer a variety of colors, shapes, and textures. Many of these plants are also easy to propagate by division.

However, they can become crowded over time and may require a little bit of pruning to keep them looking their best. In addition, some varieties can take up to 5 years before they’re mature enough for the division process.

Whether you’re growing your own hostas or sharing them with family or friends, you’ll need to learn how to split them correctly. This will help to maintain the plant’s health and beauty, while also allowing you to enjoy more of it in your yard or flowerbed.

To start, water your hostas thoroughly the day before you plan to divide them. This will help to prevent them from becoming dry and stressed.


Dividing hostas is a great way to increase your gardening variety and add new colors and shapes to your garden. These popular perennials are easy to care for and offer a wide range of textures, colors, and sizes.

The best time to divide hostas is in early spring, as soon as the unfurled leaves begin to poke through the soil. However, you can also separate hostas in the summer if necessary.

You can divide a hosta clump into as many as three or four new plants. Be sure to keep the roots intact with each division.

Before dividing the plant, water it to help reduce stress on the roots. Then, use a spade or shovel to dig around the perimeter of the plant, being careful not to damage the roots.

When you’ve dug up the hosta clump, cut it vertically into sections with a sharp knife or spade. This method, called pizza slicing, is easiest with large established clumps that would be too heavy to extract whole.


Hostas are perennial plants that come back year after year, enhancing your garden with vibrant blooms and lush greenery. However, they can become crowded and overgrown, causing them to lose their vigour and impacting the overall look of your garden.

A simple way to resolve this issue is by dividing your hostas. This process involves digging up the plant in spring, separating its roots and replanting sections of it with enough space for growth and development.

Fortunately, splitting hostas is easy and reliable! It only takes a few minutes and will improve the appearance of overcrowded plants, encourage new growth, and save you money!

The most important thing to remember when dividing hostas is that you must dig carefully, taking care not to disturb the rhizome or roots. You will also want to water your hostas a day before you begin digging in order to reduce shock.


Hostas are generally best divided in early spring or late fall when the ground is still warm but before flowering and foliage have finished developing. These times allow the hosta’s roots to settle back in without too much stress.

The first step is to prepare the planting hole. Dig out a hole that is twice as deep and as wide as the existing hosta’s root ball. Fill the new hole with slow-release fertilizer and compost to enrich the soil and encourage drainage.

Once the new hole is prepared, gently shake out the roots from the plant’s old location. This will help the roots acclimate to their new surroundings and make it easier to transplant or divide them in the future.

Alternatively, you can move the plant to a temporary spot in the yard, such as a shaded area or on a tarp or cement patio. Just be sure to protect the surrounding plants and lawn from being inundated with loose soil!
