How do I stop deer from eating my hostas? The Ultimate Guide

Watching deer devour the hosta plants you‘ve nurtured for months is disheartening. But there are numerous effective strategies to protect your hostas and deter these pernicious pests. In this comprehensive guide, we‘ll explore a multi-pronged approach so you can defend your garden with confidence.

Physical Barriers Offer Reliable Protection

Installing fencing around your hostas is the single best way to prevent deer from accessing them. While not visually appealing, physical barriers are extremely effective if installed properly. Here‘s an overview of your fencing options:

Chicken Wire Fencing

Chicken wire fencing is an affordable and easy-to-install option. Galvanized steel wire is twisted into hexagonal shapes to create a mesh pattern. Pros:

• Low cost at $70-$100 for a 100-ft roll.
• Available at any hardware store.
• Can be installed by one person. Posts spaced every 5-10 feet.

Potential cons:

• Not as durable or dense as welded wire. Deer may push through weaker spots.
• Requires ongoing maintenance to maintain tight gaps as it can sag over time.

Welded Wire Fencing

Welded wire fencing offers maximum strength thanks to wires fused at each intersection. Pros:

• Very dense, rigid, and durable material. Deer can‘t push through.
• 8-10 year lifespan. Largely maintenance free.
• 5-6 foot height optimal. Extend fence outward from plants.

Potential cons:

• More expensive at $150-$300 for a 100-ft roll.
• Heavier and harder to install than chicken wire. May need professional help.

Deer Netting

Lightweight polyethylene or nylon plastic mesh that can be draped over plants. Pros:

• Very affordable at $0.10-$0.30 per square foot.
• Easy for one person to install without tools.
• Can be applied selectively only on susceptible plants.

Potential cons:

• Not as durable or stable, may require frequent replacement.
• Movement in wind/rain can damage plants if netting rests on foliage.
• Less aesthetically pleasing.

So in summary, welded wire fencing provides maximum security if installed properly. But chicken wire and plastic netting are lower cost alternatives. Use the latter for smaller spaces.

Apply Regular Repellent Treatments

Deer have sensitive noses, so repellents with strong scents can deter them from grazing on treated plants. Here are tips for success:

• Use organic, humane formulas. Look for EPA approved products with these active ingredients: garlic, capsaicin, putrescent whole egg solids.
• Spray thoroughly. Cover all leaves, stems and flowers. Pay extra attention to new growth which is most vulnerable.
• Reapply every 2-3 weeks. Rain and environmental breakdown means repellents must be reapplied. Don‘t wait for damage – stay vigilant.
• Rotate repellents. Deer quickly adapt to scents. Switch between 2-3 different products for best results.

Recommended products:

• Deer Out Concentrate – mix of garlic, egg solids, andcap saicin. [$7 per 32 oz]
• Liquid Fence Deer & Rabbit Repellent – garlic-based. [$25 per 32 oz]
• Plantskydd Deer Repellent – made from blood meal and dried blood. [$40 per 2.2 lbs]

Talk to your local lawn and garden center specialist for advice on the best options for your environment. Proper application of quality repellents will discourage deer from browsing your garden. But don‘t expect 100% protection – keep reading for more tips.

Strategic Landscaping Provides Added Protection

Even when using repellents, some deer still slip through. You can further fortify your defenses through smart landscape design:

Obstruct Deer‘s Line of Sight

Deer feel safest eating plants they can easily see and access. Break up open sight lines by:

• Planting taller flowers/grasses around hostas like lavender, verbena, coreopsis and ornamental grasses.
• Situating hostas near structures like sheds, fences or trees.
• Allowing beneficial plants like ferns to grow around and cover hostas.

Create a Deer-Resistant Buffer Zone

Ring your garden with plants that deter deer. Excellent choices include:

• Lavender – Deer dislike the strong fragrance from this flowering perennial. Grows up to 3 feet tall.
• Bee Balm – Also known as monarda, the pungent oil in bee balm leaves makes this flower deer-resistant. Grows 2-4 feet tall.
• Butterfly Bush – Deer tend to avoid this large shrub. Provides landscape height. Grows up to 8 feet tall.
• Verbena – The stiff, prickly leaves and stems of this perennial don‘t appeal to deer. Grows 2-3 feet tall.

Mix up plant heights, colors, and textures for an aesthetically pleasing buffer zone that also masks your hostas.

Use Smell and Taste Deterrents

Deer dislike the strong scent and taste of some common items. Take advantage by scattering or hanging:

• Mothballs or ammonia-soaked rags – The overwhelming odor drives deer away.
• Deodorant soap bars – Unpleasant smell lingers on plants. Rub directly on leaves or hang in mesh bags.
• Bags of human hair – Ask your barber or hair salon to collect this unusual but potent deterrent.
• Cotton balls soaked with fragrant oils – Deer avoid strong smells like cinnamon, clove, citrus.

Use these inexpensive but effective smell and taste deterrents liberally around your garden‘s perimeter. Every little bit boosts your deer defenses.

Remedies for Damaged Hostas

If all preventative measures fail and deer nibble on your hostas, take the following recovery steps:

Remove Damaged Foliage

Clip back any munched leaves, stems or flowers until only healthy, green tissue remains. This reduces risk of disease and helps the plant direct energy into regrowth.

Install a Physical Barrier

Deer often return to plants they‘ve successfully eaten before. Immediately erect fencing to prevent repeated damage. Netting also deters deer from taking a second bite.

Apply Repellent

Treat remaining undamaged foliage and stalks with deer repellent so the plants no longer taste appealing. Reapply frequently.

Water and Fertilize

Well-nourished, vigorously growing hostas better withstand and recover from grazing damage. Apply organic fertilizer and be diligent about watering for fastest regrowth.

Consider Division

Large hosta clumps are more susceptible to substantial deer damage. You may have better regrowth luck by dividing them into smaller plantlets.

Prevent Re-Grazing

After deer penetrate your garden‘s defenses, implement these measures to avoid repeated attacks:

• Eliminate food sources like fallen apples that could draw deer.
• Reinforce fencing with another layer to create a deer-proof barrier. Amend gaps or weak spots.
• Increase hanging deterrents like soap bars and hair bags which sway in the wind. Movement and scent work together to repel deer.
• Add a motion-activated sprinkler that sprays deer with a sharp burst of water when they enter the garden.

Make Your Own Organic Deer Repellent Sprays

Concocting your own liquid repellent is an inexpensive way to harness the power of strong scents. Here are 5 homemade recipes to try:

Garlic Repellent Spray

• Ingredients: 4 cloves garlic, 2 cups water, 2 tbsp dish soap, 1 quart water
• Directions: Blend garlic cloves and 2 cups water. Allow to steep 24 hrs. Strain and mix liquid with dish soap and 1 quart water. Apply liberally to foliage.

Hot Pepper Repellent Spray

• Ingredients: 2 hot peppers, 2 cups water, 1 tbsp dish soap, 1 quart water
• Directions: Puree hot peppers and 2 cups water. Steep 24 hrs then strain. Mix liquid with dish soap and 1 quart water. Shake before spraying plants.

Vinegar Repellent Spray

• Ingredients: 2 parts water, 1 part white or apple cider vinegar, dash of hot sauce (optional)
• Directions: Combine ingredients in spray bottle. Apply evenly to plants every 5-7 days. The acidic taste drives deer away.

Putrescent Egg Spray

• Ingredients: 1 whole egg, 1 cup water
• Directions: Whisk egg and water. Sit in hot sun 3-4 days until rotten smell develops. Strain, mix with 1 quart water and apply to plants.

Predator Urine Spray

• Ingredients: 1 oz predator urine (coyote, fox), 1 quart water
• Directions: Mix 1 oz predator urine with 1 quart water. Shake vigorously before spraying exterior of garden, fences, and any trails deer use to enter.

Always test homemade sprays on a few leaves first before wide application to ensure plant compatibility. Reapply every 7-10 days, especially after rain.

Key Takeaways

Protecting your beloved hostas from deer invasion requires an integrated, multi-layer strategy:

• Prioritize physical barriers first – Fencing blocks access while netting and scare deterrents discourage entry.
• Treat plants with organic repellents – Alter taste/smell to make plants unappealing. Reapply often.
• Strategically landscape – Mask hostas, obstruct deer vision, create unfriendly buffer zones.
• Deploy smell/taste deterrents – Use soaps, hair, predator urine around the perimeter.
• Persist and adapt – When deer sneak through, strengthen defenses and remedy damage quickly.

A diligent, evolving regimen of fencing, repellents, landscaping and deterrents will defend your hosta collection. With commitment and resilience, you can outsmart those deer and protect your garden investment. The sense of satisfaction is well worth the effort.
