An Introduction to Deer, Hostas, and Their Challenging Relationship

Before diving into solutions, it helps to understand why deer target hostas in the first place.

Hostas are herbaceous perennials native to northeast Asia. They‘re known for their attractive foliage which comes in green, blue, yellow and variegated forms. Their leaf shapes range from slender to wide ovals. Mature sizes span from petite 10-inch plants to giant 5-foot clumps.

Hostas thrive in moist, organic-rich soil and light to deep shade. These conditions are prevalent in woodland environments – prime deer habitat. Deer browse on plants like hostas that offer ample, tender foliage and lack chemical defenses. According to research from Rutgers University, hostas are one of the top 10 plants damaged by deer.

But why do deer preferentially eat certain hosta varieties over others? Next, we‘ll explore the physical and chemical traits that make some hostas naturally deer-resistant.

Physical Characteristics of Deer-Resistant Hostas

Deer use their senses of sight, smell and taste to forage. Hostas with the following physical traits tend to be avoided:

• Thick or waxier leaves – Deer prefer young, tender growth. Thick mature leaves with a waxy cuticle are less palatable.
• Variegated foliage – The white, yellow or ivory margins on variegated hostas may deter deer.
• Blue-green hues – Cooler tones of blue, sea green and blue-green are less favored. Deer gravitate toward greens and yellow-greens.
• Wide leaves – Deer prefer narrow, strap-like leaves and new shoots. Hostas with wide ovals or heart-shaped leaves are passed over.
• Textured leaves – Hostas with puckered, ruffled or heavily veined leaves are avoided. Smooth leaves are tastier.

One study published in the Journal of Environmental Horticulture compared the feeding preferences of deer for hosta cultivars with varying physical traits. The least damaged hostas had thicker leaves, variegation, moderate to severe leaf rugosity, and heart-shaped leaf bases.

Now that you know what physical features make hostas less palatable, let‘s explore fragrant hostas that deter deer through their scent.

Fragrant Hostas Deer Avoid

Deer also have a strong sense of smell. Hostas cultivars with fragrant flowers or foliage contain chemical compounds that deter deer.

Popular scented hostas include:

• ‘Guacamole‘ – Foliage has a sweet, spicy fragrance. Grows 24 inches tall and wide with gold textured leaves.
• ‘Fragrant Bouquet‘ – Heavily corrugated green leaves emit a lavender scent. Grows 20 inches tall and 40 inches wide.
• ‘Garlic Kisses‘ – Leaves have a mild garlic scent. Grows 14 inches tall and 32 inches wide with white-centered green leaves.
• ‘Stinky‘ – Dense mounds of oval blue-green leaves smell like garlic and onions. Grows 20 inches tall and 3 feet wide.

The strong aromas of these hostas are thought to mimic commercial deer repellents, causing deer to avoid them.

Now that you know what physical and chemical traits make hostas deer-resistant, let‘s look at popular resistant varieties you can grow with confidence.

Top Hosta Varieties Deer Avoid

Here are some of the top-rated hosta cultivars known for deer resistance based on research and gardener experience:

• ‘Francee‘ – A classic green hosta with a 1-2 inch wide white margin. Slug resistant. Grows 18 inches tall and wide.
• ‘June‘ – Blue heart-shaped leaves with yellow margins. Grows 15 inches tall, 30 inches wide.
• ‘Halcyon‘ – Lavender-scented blue-green foliage. Grows 20 inches tall, 40 inches wide.
• ‘Royal Standard‘ – Green leaves with white backs. Forms a dense 20 inch tall, 40 inch wide clump.
• ‘Captain Kirk‘ – Thick blue corrugated leaves dislikes by deer. Grows 28 inches tall, 5 feet wide.
• ‘Golden Tiara‘ – Chartreuse leaves with lightly rippled texture. Grows 10 inches tall, 20 inches wide.
• ‘Minuteman‘ – Thick blue-green leaves make this a tough deer and slug resistant plant. Grows 12 inches tall and wide.
• ‘Praying Hands‘ – Unusual tubular leaves seem to deter deer. Grows 15 inches tall, 2 feet wide.

As you choose hostas, opt for varieties with multiple deer-resistant traits like thick, fragrant foliage or variegation. Next, let‘s look at non-hosta plants that resemble hostas and also deter deer.

Deer-Resistant Alternatives that Look Like Hostas

Some perennials share a similar appearance to hostas but contain chemical compounds that deter deer. Here are a few hosta look-alikes to consider:

Lamb‘s Ear (Stachys byzantina)

• Grown for its velvety, silver-grey foliage. Has a rough, furry leaf texture deer dislike.
• Forms dense 12 inch tall, 12 inch wide clumps. Thrives in full sun to partial shade.

Astilbe (False Spirea)

• Feathery, fern-like foliage with plumes of feather-like summer flowers. Unappetizing to deer.
• Grows 1-3 feet tall depending on variety. Prefers partial to full shade.

Bigroot Geranium (Geranium macrorrhizum)

• Aromatic, rounded lobed leaves emerge minty scented. Grows 12-18 inches tall.
• Spreads by underground rhizomes. Pink spring flowers. Does well in sun or shade.

Spotted Deadnettle (Lamium maculatum)

• Features silver and green leaves with purple-pink blooms in spring. Disliked by deer.
• Grows 4-6 inches tall, spreading by stolons. Thrives in partial to full shade.

By interplanting hostas with these look-alikes, you can create beautiful, deer-resistant combinations. Next, let‘s talk about how to help hostas recover if they do suffer deer damage.

Helping Hostas Rebound After Deer Damage

If deer help themselves to a snack of hosta leaves, don‘t despair. The good news is hostas can regrow even if deer eat all their foliage. Their roots are resilient and will generate fresh leaves each spring.

However, frequent grazing weakens the plant over time. To help damaged hostas recover:

• Apply an organic fertilizer to restore nutrients lost to grazing. Options include compost, fish emulsion, seaweed extract or all-purpose blends.

• Install physical barriers like flexible netting or wire mesh cages to prevent further grazing and allow the plants to re-leaf.

• Consider motion-activated sprinklers or lights to scare deer away from newly emerged foliage.

• Interplant lavender, alliums or other deer-deterring plants around vulnerable areas. Their strong scent can mask the hosta‘s appeal.

With some TLC and preventative measures, your defoliated hostas will soon look lush and vibrant again.

Now that you know hostas can rebound from deer damage, let‘s explore proactive ways to stop deer grazing in the first place.

6 Ways to Protect Hostas from Hungry Deer

A multi-tiered strategy works best to safeguard hostas from deer. Try combining several of the following tactics:

1. Use Physical Barriers

Physical barriers provide the strongest form of protection. Effective options include:

• Plastic or wire mesh cages around individual hosta clumps or pots.

• Flexible plastic or nylon deer netting mounted on posts to protect beds.

• 8-foot tall plastic or wire perimeter fencing around the entire garden.

• Motion-activated sprinklers that scare away deer with a sudden spray of water.

2. Apply Commercial Repellents

Commercial deer repellents create an unpalatable tasting or smelling barrier on plant surfaces. Apply every 2-4 weeks for best results:

• Liquid, ready-to-spray formulas – Contain compounds like putrescent egg solids that disgust deer. Spray onto leaves.

• Granular or pellet repellents – Applied by hand or broadcast spreader around gardens. Activated by rain and watering.

• Scent or taste repellents – Added to water and sprayed on. Use sticky sticking agents so rain doesn‘t wash away.

3. Make Homemade Repellents

Whip up homemade sprays with ingredients like:

• Garlic – Contains allicins and sulfurs that deter deer. Use chopped cloves or garlic powder.

• Dried hot peppers – Capsaicin irritates deer senses. Cayenne, habanero and jalapeño all work.

• Soap – Mix 2 Tbs. liquid castile or other soap into 1 gallon of water. Spray onto foliage.

• Eggs – The sulfur smell of eggs repels deer. Mix 1 whole raw egg into 1 gallon of water.

4. Use Strongly Scented Companion Plants

Plant deer-repelling aromatics like lavender, catmint, and sage around vulnerable gardens. The strong scent masks tempting plants.

5. Install frightening devices

Motion-activated sprinklers, lights, or sounds startle deer away. Place them near affected plants:

• Motion-activated sprinkler – Connect to a hose or outdoor faucet. Set the motion sensor to detect deer.

• Ultrasonic deterrent – Emits high-frequency sounds when triggered by movement.

• Motion-sensing light – Illuminates nighttime deer. Can be paired with other deterrents.

6. Use Dogs for Their Scent

Allow dogs to regularly roam or relieve themselves around the garden. Their scent and presence helps deter deer.

As you can see, protecting hostas isn‘t about one magic solution. The key is using multiple deterrents suited to your specific environment.

Now that we‘ve covered how to stop deer damage, let‘s end with tips on safely using coffee grounds to fertilize hostas.

Are Coffee Grounds Good for Hostas?

Coffee grounds won‘t fend off deer, but they are beneficial to hostas when used as an occasional soil amendment.

The grounds contain nitrogen, phosphorus, potassium and other nutrients that gradually release into the soil. The grounds also acidify soil, which hostas prefer.

Research by Mississippi State University found hostas fertilized with coffee grounds produced bigger plants with more flowers compared to the control.

To safely use grounds:

• Work 1-2 tablespoons into the top few inches of soil around each plant every 2-3 weeks.

• Avoid piling grounds next to the crown which can lead to rot.

• Mix well into soil to prevent molding.

• Monitor plants for leaf burn, which signals over-application.

While coffee grounds won‘t stop deer, they offer an easy, eco-friendly way to fertilize hostas.

Let‘s Review the Key Tips for Protecting Hostas

We‘ve covered a lot of ground here! To recap, here are the key tips for growing vigorous hostas that deer avoid:

• Select hosta varieties with physical and chemical deterrents like thick, blue-green or scented foliage

• Plant deer-resistant perennials like lamb‘s ear and astilbe that resemble hostas

• Use barriers, repellents, and frightening devices to proactively protect plants from grazing

• Fertilize damaged hostas to help them recover, and take steps to prevent future damage

• Use coffee grounds as a supplemental fertilizer to nourish hostas

The bottom line is you can enjoy stunning hostas, even in areas with hungry deer. Assess your deer pressure, then implement a layered strategy tailored to your needs.

With the information in this guide, you now have everything you need to design, plant and protect a spectacular shade garden filled with lush, thriving hostas. I wish you the best of luck, and happy gardening!
