How to Plant, Grow, and Care for Hostas
Hostas are cut back the fall after a few frosts. Otherwise, these hardy perennials require almost no care and are also perfect for a garden that doesn’t get too much sun. Reliable and easy to grow, hostas are long-livedāand may even outlive the gardener! Learn more about growing and caring for hostas.
About Hostas
What’s neat about hostas is that there are so many sizes, heights, textures, and colors to work with! They fit into so many different kinds of gardens (patio, border, container, rock, shade) and are cold-hardy, too.
Most varieties tend to have a spread and height of between 1 and 3 feet, but larger or smaller varieties are readily available. Leaf colors include variegated white, lime green, and blue-green, to name just a few. The texture and shape of hosta leaves are also diverse, ranging from smooth and narrow to ridged and heart-shaped.
Though mainly known for their attractive foliage, the plants also produce lovely flowers from early summer to early fall in pink, lavender, light blue, or white. Hummingbirds and other pollinators love the flowers, and the flowers may even be fragrant, depending on variety.
Note: Slugs, snails, rabbits, and especially deer like hostas almost as much as people do. Keep this in mind if you have deer regularly wandering into your garden, as they will readily graze a hosta patch down to just stems.
Planting
When to Plant Hostas
- Buy hostas as dormant, bare-root divisions or potted plants and plant them in the spring or in the fall.
- Hostas can be planted during the summer growing season, but will need extra attention (mostly watering) to ensure that they do not succumb to the heat of summer.
Choosing and Preparing a Planting Site
- Hostas do best in partial sun or dappled shade, but will do fine in deep shade, too.
- Hostasā large leaves do not lend themselves well to intense full sun.
- Once established, they can take the summer heat and withstand mild droughts.
- Soil should be well-draining and ideally have a pH between slightly acidic and neutral (6.5 to 7.0).
How to Plant Hostas
- Dig a hole that’s about twice the width and depth of the root ball of the plant. Loosening the soil in the planting area will benefit the hosta’s roots as they expand outward.
- Set the plants in the hole so that the crown (base) of the plant is even with the surrounding soil and any emerging leaf tips are visible at the soil surface.
- If buying potted hostas, plant them at the same soil level as in the pot.
- Gently dampen the soil around the plants and water until soil is moist to settle the roots.
Care
How to Care for Hostas
- Apply a well-balanced, slow-release fertilizer after planting or when growth emerges in the spring.
- Keep the soil moist but not soaked.
- If the soil tends to dry out quickly, consider placing mulch around the plants to help retain moisture, but be aware that mulch can be a hiding place for slugs.
- Remove flower stalks after bloom to encourage new growth.
- Many hosta cultivars have nice color in fall, so let them thrive until they start to suffer from frosts.
- In late fall, after a few frosts, hostas will flatten out and get mushy. We suggest cutting them back to avoid slug and disease issues. Clean up around the plants and remove brown leaves. However, if you run out of time, you could also wait to cut them back until spring.
- Transplanting and dividing is best done in early spring when the leaves just begin to emerge.
Transplanting or Dividing Hostas
Hostas do not usually need dividing for their health. If they have less space, they’ll simply grow less quickly. However, if you wish to divide a hosta for a neater garden appearance, it’s best to do so in early spring once the āeyesā or growing tips start to emerge from the ground. This is also a good time to move or transplant a hosta to a new site.
Leave as much of the root attached as possible to each crown or plant. Plant the new hostas at the same soil level as they were previously. Water well until established.

Pests/Diseases
- Slugs and snails: If you see irregular holes along the leaf’s edges or entire leaves chewed off at the stem nocturnal slugs may be the culprit. Look for shiny slime trails on the leaves or on the ground around the plants.
- Deer: It’s true that deer love hosta. To discourage deer, use fencing or motion-sensitive sprinklers. Speak to your local garden center about odor-based sprays and deer repellents; the deer will taste the distasteful repellent first. Here’s an example.
- Rabbits: If you see clean-cut chew marks on young hosta stems and leaves you may have rabbits in your garden. Look for dropped leaves and rabbit droppings on the ground and around the plants.
Recommended Varieties
Once you start exploring hostas, you’ll find they get rather addictive! From 4-inch miniature hostas to 6-foot-wide giant hostas, there’s a hosta variety to fit any situation from large borders to tiny rock gardens. Here are just a few:
- H. fotunei āAureo Marginata’: Deep-green oval leaves accented by a golden edge.
- H. x āBlue Cadetā: A small hosta with heart-shaped, bluish leaves. It makes for a nice edging plant. In mid-summer it blooms with mauve-blue flowers.
- For sunnier spots, select plants from the Hosta plantaginea group. These plants also tend to have fragrant flowers in late summer. āAugust Moonā, āHoneybellsā, and āSum and Substanceā are a few of the varieties in this category.
Wit and Wisdom
- Young hosta leaves are edible. Known as urui in Japan, theyāre commonly boiled, fried in tempura, or eaten raw. The flavor is similar to lettuce and asparagus.
- If you wish to remove your hostas, cut off the leaves to the ground and then dig out the crown located just below ground level. Pour vinegar or boiling water over the plant. If you have a larger area of hostas that you want to remove, cut the leaves off, remove the crowns and then cover the area with black plastic for the rest of the growing season.
Wow, informative article about hostas. I'm also growing hostas tree.
I have several hosts plants surrounding a tree. I was cleaning up the dead leaves for the winter when I noticed the dirt mounded up where every plant is. The dirt is in loose, granular fashion. As I was pulling on the leaves, the crown, root and all came out of the ground very easily. Itās like something is burrowing in the ground under the plants and eating the roots. Anyone ever experience this? I get several compliments every year how big and beautiful they are, but Iām afraid Iām losing them to some animal. The only animal Iāve ever seen around them are rabbits, but they donāt mound up dirt like this and eat only the roots. Thereās no rabbit droppings either. Help!!
Voles? No, I don't know how to get rid of them. They destroyed one of my flower gardens last year and I couldn't catch any of them. Look for tunnels. They don't make mounds of dirt like moles do. Good luck.
I have tried to order kid's books, but it says you don't ship to Canada. Why Don't you ship to Canada?
Hi, Charles, Thank you for your interest in The Almanac for Kids. The cost of shipping to Canada from the U.S. has proven to be prohibitive. We recommend that you order Almanac publications from Amazon.ca; it’s efficient and cost effective, if no stores near you carry them.
We hope this helps!
