How to Grow Hostas
As an Amazon Associate we earn from qualifying purchases.
How to grow hostas starts with shade. Hostas are shade-tolerant perennials grown mainly for their leaves, and the extension guides we opened agree on the core rules: choose partial to full shade, give them rich soil that drains well, set the crown at soil level, and keep the soil moist without letting it turn soggy. This guide follows those steps in the order you would work through them in a bed.
The guides also disagree on a few points, mainly planting depth, plant size and fertilizer timing. Where they do, we show both answers instead of picking one, and we list what the pages do not cover at the end.
Quick answer
- Plant hostas in partial to full shade, away from hot afternoon sun and out of wet, poorly drained spots.
- Set the crown just above soil level, in a hole slightly shallower than the root ball and at least one and a half times as wide.
- Give about an inch of water a week when rain does not supply it, and use a light layer of mulch to conserve moisture.
- Divide clumps every three to five years in early spring, and expect several years before a new hosta reaches full size.
Light: partial to full shade, with afternoon relief
Hostas are shade plants, but how much shade they need depends on the cultivar. The Clemson factsheet calls hostas shade-tolerant perennials and says most do best with afternoon shade. The Nebraska guide places hostas in partial to full shade in its climate, and says some cultivars take partial sun, particularly in cooler northern areas. The Georgia guide puts the range from partial sun to dense shade and advises checking each cultivar’s needs before planting.
Afternoon sun is the main risk. The Nebraska guide says sun-tolerant hostas do best in morning and midday sun, because afternoon and late-day sun fades and burns the leaves. Clemson adds that most blue hostas need shade, and that too much sun leaves the color pale and can cause dieback in dry spells. The Colorado PlantTalk page warns that at higher elevations, too much sun can scorch the leaves.
Dense shade is also a problem. The Nebraska guide says hostas need some light, so the dark shade under low-branched evergreens may not give them enough. Under shade trees, it suggests setting small hostas between the existing roots rather than adding a lot of new soil. Adding more than two to three inches of soil under the canopy can help the hostas, the guide notes, but it may cut the oxygen the tree needs and risk tree decline.
Wind matters too. The Nebraska guide asks for a site sheltered from wind and hail, because most cultivars are damaged by winds above 35 miles per hour, and tattered leaves usually stay tattered.
Soil that drains and holds organic matter
All of the guides start with drainage. The Nebraska guide asks for well-drained, slightly acidic soil, and recommends working two to three inches of compost into the top 10 inches. The Georgia guide says hostas prefer well-drained soil amended with compost or rotted manure, and that they do best in raised beds. For soil options built for raised planters, see our guide to soil for raised planters.
Waterlogging is the failure to avoid. The Nebraska guide says poorly drained spots can cause root and crown rot. NC State describes hostas as intolerant of soggy soil, especially in winter, and the Georgia guide says they will not tolerate soggy conditions during the winter months. The Colorado PlantTalk page advises a generous amount of organic matter before planting, because it improves moisture retention and encourages good root development.
Soil pH is less settled. NC State gives a moist, slightly acidic soil as the target, and the Nebraska guide also says slightly acidic. The Georgia guide gives no number, but recommends a soil test to decide how much lime and fertilizer to add. A test is the simplest way to answer the question for your own bed.
Planting: crown level, room to grow
Timing comes first. The Clemson factsheet says hostas can be planted, transplanted or divided in early fall or in spring before the leaves unfold. The Nebraska guide gives spring after the shoots emerge, or late summer after bloom has ended and temperatures have dropped. Its warning about late-summer work is that a plant moved then needs at least one full growing season before active top growth resumes.
For the hole, the Nebraska guide asks for one slightly shallower than the root ball and at least one and a half times as wide. Set the crown just above soil level, add soil as needed, and do not bury the crown or tamp the fill. Water thoroughly to settle the soil and remove air pockets. The Georgia guide is different: it says to dig a hole as deep as the root ball and at least twice as wide, then backfill and water well. Both guides agree on the watering step.
Spacing depends on size. Clemson suggests one to three feet between plants. The Nebraska guide gives plant-to-plant spacing by cultivar size: eight to 12 inches for small hostas, 12 to 24 inches for medium ones, and 36 inches for large ones. The Georgia guide says to space hostas according to their spread at maturity, which points to the width the plant will reach.
Dividing and keeping clumps healthy
Division keeps a clump vigorous. NC State says to divide every three to five years in early spring, as the leaves emerge. Georgia says most hostas can be divided in four to five years, depending on the vigor of the clump, and that each division needs an eye, or growing point. Very small divisions establish slowly, the guide adds. Clemson says hostas do best when left undisturbed for several years, so divide only when the clump needs it.
The Nebraska guide describes a fairy ring, a clump with a dead center and healthy leaves around the edge. Dividing that clump can rejuvenate it.
Water and feed without overdoing either
Plan on about an inch of water a week. Clemson says hostas need an inch or more a week when rain does not supply it, and more in hot weather, in full sun, or where tree and shrub roots compete for water. Nebraska says most hostas need supplemental irrigation for good growth there, even though many tolerate drought once established.
Drip tubing or soaker hoses are the Nebraska guide’s first choice, because they keep the foliage dry. Dry leaves also make blue-leaved cultivars look more intense, the guide says. Water in the morning so any mulch dries before evening.
Feed lightly. Clemson suggests a slow-release, well-balanced fertilizer in early spring as the first growth starts, and warns against excessive rates. The Nebraska guide says no more than one-eighth pound of actual nitrogen is needed for a 125-square-foot bed, because high nitrogen gives soft leaves that wilt readily and are more open to foliar disease.
Mulch is the last piece. In early summer, the Nebraska guide suggests about an inch of loose organic mulch to inhibit weeds, reduce water loss and lessen soil compaction. A thicker layer, it warns, is likely to promote slugs. The Georgia guide advises mulch to help conserve moisture.
Slugs, deer and voles
Slugs are the pest the guides name most often. Clemson calls them the most common problem of hostas. The Nebraska guide says slugs and snails thrive in moist conditions, especially in beds that are overwatered or heavily mulched, and that leaf litter and neglected compost piles give them cover. They feed at night or in cool parts of the day, and the leaves nearest the ground and the thin-leaved cultivars are hit first.
The cultural steps come first. The Nebraska guide suggests removing excess mulch and organic matter, and changing how often and how you water, so the bed is less friendly to slugs. Clemson recommends cleaning up around the plants after they die back in fall, which it links to slug control. NC State says to watch the leaves for snails, slugs and nematodes.
Deer, rabbits and voles are the animal problems. Clemson says voles feed on the root system and can kill a plant, and that deer eat the foliage and leaf stalks. The Nebraska guide lists fencing and wire cages as physical barriers that can limit damage from deer, rabbits, voles and squirrels. This guide does not cover chemical slug or animal controls. For those, follow the product label and local rules.
Winter, dormancy and cleanup
Hostas go dormant. The Nebraska guide says the foliage dies back to the ground at 28 degrees Fahrenheit or below, so the plant offers no winter display. NC State says hostas need a dormant period below 40 degrees Fahrenheit for a couple of months. Clemson calls hostas very long-lived, and says they may outlive their gardeners in a good location with reasonable care.
Protect new plants in their first winter. The Nebraska guide advises winter mulch on newly planted hostas, to limit damage from repeated freezing and thawing of the soil. Before the mulch goes on, remove the remaining foliage. In early spring, before growth shows, rake off the winter mulch along with the leaf debris. For a seasonal checklist, see preparing raised beds for winter.
Cultivars: match size and light
The Nebraska guide lists cultivars by mature size, leaf color, sun tolerance and use. The table gives five examples from that list, with the mature height and width the guide gives for plants three to five years old.
| Cultivar | Height (in) | Width (in) | Leaf and use, as the guide lists them |
|---|---|---|---|
| Gum Drop | 6 | 10 | Small green-blue leaves, mound |
| Golden Tiara | 12 | 18 | Gold margins, edger, drifts |
| August Moon | 20 | 20 | Yellow leaves, specimen, drifts, accent |
| Krossa Regal | 30 | 30 | Frosty blue leaves, vase-shaped |
| Sum and Substance | 36 | 48 | Chartreuse-golden leaves, specimen, accent |
Sizes do not match across sources. Clemson gives ‘Royal Standard’ as 18 inches tall and 38 inches wide. The Nebraska table gives 36 by 30 inches for the same cultivar, and the Colorado page gives 12 to 18 inches tall. Clemson gives Sum and Substance as 30 inches tall and 60 inches wide, against 36 by 48 inches in the Nebraska table. Treat any listed size as a guide, and check the plant label or the grower’s sheet for the cultivar you pick.
Light tolerance varies within a species, too. Clemson says the plantain lily, Hosta plantaginea, is the most heat- and sun-tolerant species it names, and that it grows in shade to about three-quarters of a day of sun. Fortune’s plantain lily prefers shade to about half a day of sun. Clemson also notes that Sum and Substance colors best in sun, so a cultivar that suits a deep corner may not suit a bright one.
Leaf and root problems to watch for
Leaves show where a plant is struggling. Pale color, fading and dieback in dry spells point to too much sun, according to Clemson. Brown leaf edges can come from low humidity and wind, which the Nebraska guide names. Soft leaves that wilt readily can point to too much nitrogen, the same guide says.
What we could not verify
What the sources do not say
The sources do not agree on planting depth or spacing, and this guide does not settle that disagreement for you. The pages do not give one hardiness zone for hostas, because each describes its own climate: Nebraska, South Carolina, Georgia, North Carolina and Colorado. The Georgia text cites a 1999 publication and the Clemson factsheet was revised in 2019, so some cultivar names and sizes may have changed. The Minnesota extension pages returned HTTP 403, so their guidance on yellow and gold cultivars is not included. The pages we opened do not give a soil pH range that all agree on, and they do not give the hours of sun a shade-tolerant hosta needs in a hot climate. Nothing in this guide is a product claim.
How we chose
We limited the guide to university and state extension pages that cover hostas grown in a garden. We opened six pages that returned HTTP 200. Five gave usable culture information, and we relied on them. The sixth was an Iowa State store listing with only a product description, so we left it out. Three other extension pages returned HTTP 403 and do not count. Where pages disagree, we report both answers. Cultivars appear only as examples from the guides, and we recommend no products.
Frequently asked questions
Can hostas grow in full shade?
Many can, but the guides do not agree that full shade is best. Nebraska says dense shade under low evergreens may not give hostas enough light. Clemson says most hostas do best in shade with afternoon relief. NC State says blue-leaved forms need deep shade, so check the cultivar before you choose a dark corner.
How deep should a hosta be planted?
The Nebraska guide says to set the crown just above soil level, in a hole slightly shallower than the root ball. The Georgia guide asks for a hole as deep as the root ball and at least twice as wide. Both guides say to water well after planting, and the depth you choose should keep the crown at the soil line.
How much water does a hosta need?
Clemson says an inch or more a week when rain does not supply it, and more in heat or full sun. Nebraska prefers drip tubing or soaker hoses to overhead watering, because they keep the leaves dry. Keep the soil moist, not wet, and water in the morning so any mulch can dry before evening.
Why are my hosta leaves turning brown?
The sources name several causes. Too much sun fades the leaves and can cause dieback in dry spells, according to Clemson. Low humidity and wind can brown or dry the leaves, and the Nebraska guide says winds above 35 miles per hour damage most cultivars. Check the exposure first, then the water, before you change anything else.
When should hostas be divided?
NC State says every three to five years in early spring, as the leaves emerge. Georgia says most can be divided in four to five years, depending on the vigor of the clump. The Nebraska guide says dividing can rejuvenate a clump with a dead center, and Clemson says hostas do best left undisturbed for several years.
