Growing Hostas in Central Ohio Landscapes

Hostas are the workhorse of every shade bed I install in Central Ohio. Easy to grow, dependable, and they come back bigger every year for at least the first decade. But I get more questions about hostas than almost any other plant, mostly because the wrong variety in the wrong spot turns into a slug-chewed, sun-scorched mess by August. I’ve been planting and dividing hostas across Pickaway, Franklin, and Fairfield counties for more than ten years, and here is everything I would tell a homeowner before they buy another one.

Do hostas grow well in Central Ohio?

Yes, hostas are one of the best-suited perennials for our zone. Central Ohio sits in USDA zone 6a to 6b, and hostas thrive between zones 3 and 9. The combination of cold winters that give them the dormancy they need and decent summer rainfall in a typical year makes our area ideal. OSU Extension considers hostas one of the top recommended shade perennials for Ohio landscapes.

That said, “shade perennial” is the key phrase. A hosta planted in full afternoon sun in a Circleville front yard with no tree cover will fry by July. I see it every summer. On a Pickerington property I service, the homeowner had planted Sum and Substance against a south-facing brick wall and could not figure out why the leaves looked bleached and crispy. We dug them in October, moved them under a maple on the north side, and they doubled in size the next summer.

How much sun do hostas tolerate in Ohio?

It depends on the variety and the leaf color. As a general rule:

• Blue-leaf hostas (Halcyon, Krossa Regal, Blue Mouse Ears): morning sun only, deep afternoon shade
• Green-leaf hostas (Royal Standard, Guacamole): morning sun and dappled afternoon shade
• Gold and yellow-leaf hostas (Sum and Substance, August Moon): need 4 to 6 hours of morning sun to develop color
• Variegated hostas (Patriot, Francee, Wide Brim): morning sun, no hot afternoon exposure

I tell clients to think of it as east side of the house good, north side great, south or west side risky. On a Lancaster property where the only available bed was the west side under a dogwood, I planted Royal Standard and Guacamole because they handle a few hours of late-afternoon sun better than the blues. They have looked good for three seasons.

When is the best time to plant hostas in Central Ohio?

Early September through mid-October is the gold-standard window for planting or dividing hostas in our zone. Soil temperatures are still warm enough to drive root growth, the air temperatures are cooling, and natural rainfall picks up. Roots establish through October and November under the soil long after the leaves have died back.

Spring planting in late April through mid-May is the second-best window. Container-grown hostas can technically go in any time the soil is workable, but a July or August planting requires babysitting the watering for weeks. Bare-root divisions in July are a bad idea. I covered the why in our guide to planting perennials in July in Ohio.

On a Chillicothe shade bed I redid last fall, we planted 22 hostas of six varieties between September 18 and October 5. The bed came up this April looking like it had been there for years. The homeowner had been told by a previous landscaper that hostas needed to go in during spring. They do not. Fall is better.

Which hosta varieties work best in our area?

These are the ones I plant most often on client jobs because they perform reliably in Central Ohio conditions:

• Sum and Substance — giant chartreuse leaves, can hit 4 feet across, handles more sun than most
• Patriot — green leaves with crisp white margins, classic look, 2 feet tall
• Halcyon — blue-green leaves, medium size, deer-resistant reputation
• Francee — green with white edges, very forgiving in less-than-ideal spots
• Blue Mouse Ears — small, tidy, perfect for front-of-border or container use
• Royal Standard — large green leaves, fragrant white flowers in August
• Guacamole — green and gold variegation, fragrant flowers, vigorous
• Empress Wu — the biggest hosta on the market, makes a statement under a mature tree

If you only buy one, make it Francee. I have planted Francee in dozens of beds across Pickaway and Fairfield counties and have never had one fail.

How do I plant a hosta correctly?

Skip the deep hole. Hostas have crowns that sit at or just above the soil line and root systems that spread wider than they go deep. Here is my standard install:

1. Dig a hole twice as wide as the root ball and only as deep
2. Loosen the bottom of the hole with a fork to break up clay pan
3. Place the hosta so the crown is level with the surrounding soil, never buried
4. Backfill with the native soil mixed with a shovel of compost
5. Water in slowly until the soil is fully saturated
6. Mulch 2 inches deep, keeping mulch 1 inch off the crown
7. Tag the location if you are planting in early spring before the eyes emerge

The crown depth is what kills hostas more than anything else. Buried crowns rot in our clay soils. If you can see the top of the crown peeking through the mulch, you are right where you want to be.

How do I deal with slugs on hostas in Ohio?

Slugs are the single biggest cosmetic problem on Central Ohio hostas, especially in wet summers. The damage looks like ragged holes chewed through the middle of the leaves, usually starting in June. By August in a bad year, the leaves can look lacy.

What works in my client beds:

• Sluggo (iron phosphate) — pet and pollinator safe, scatter every 2 weeks from May through August
• Beer traps — old-school but they work in small beds
• Copper tape around the bed edges in raised situations
• Thinning the mulch to under 2 inches so the surface dries between rains
• Watering in the morning so the soil surface dries by evening

What does not work: salt, eggshells, and most of the homemade remedies you find online. I tried the eggshell trick on a Canal Winchester client’s bed in 2023 because she asked. The slugs walked over them.

Thick-leafed varieties like Halcyon and Blue Mouse Ears resist slug damage better than thin-leafed varieties like Sum and Substance. If you have a chronic slug problem and want a low-maintenance fix, switch varieties.

What about deer?

Hostas are deer candy. I cannot say this strongly enough. In the rural parts of Pickaway and Ross counties, an unprotected hosta bed will get browsed to the ground in a single overnight visit.

On a Washington Court House property last May, a client had me install 14 hostas on a Tuesday. By Friday morning, eight of them were chewed to nubs. The deer had walked the back property line and worked their way along the bed. We fenced the area and replanted in fall, and three years later the bed is mature.

If you live in a deer corridor, you have three options: fence, deer repellent sprayed weekly through the growing season, or pick a different plant. There is no truly deer-proof hosta. The Halcyon and Blue Mouse Ears claims of deer resistance hold up only in low-pressure suburban yards.

How and when do I divide hostas?

Hostas benefit from division every 4 to 6 years, both to control size and to refresh the center of the clump. Late August through September is the right time for division in Central Ohio.

The method I use:

1. Water the plant deeply two days before
2. Dig the entire clump out with a sharp spade
3. Wash off enough soil to see the natural divisions in the crown
4. Cut through the crown with a sharp knife or spade, keeping 2 to 3 eyes per division
5. Replant immediately at the same depth
6. Water in heavily and mulch

A mature Sum and Substance can give you 6 to 10 plantable divisions. I have built whole shade beds from one mature mother plant.

Quick hosta checklist for Central Ohio

• Match the variety to the sun exposure
• Plant in September or April, not July
• Set the crown at soil level, never buried
• Mulch 2 inches, off the crown
• Scatter Sluggo every 2 weeks from May to August
• Assume deer will find them
• Divide every 4 to 6 years in late summer

If you want help planning a shade bed or refreshing one that has gone downhill, that is the kind of install we do every fall. Our mulch install service pairs well with a hosta bed refresh.
