Deer and Petunias: Do Deer Eat Petunias?

Updated September 2026 · Garden Advice Guide

Yes, deer eat petunias, and they go for the flowers first. Petunias are not deer resistant. Deer and petunias are a poor match in any yard with regular deer traffic, because petunias are soft, water-rich, and only mildly scented, which puts them in the middle of every browse-resistance list rather than the safe end. The sticky hairs on the leaves buy you a little protection, and that's all they buy.

The good news: petunias recover from browsing better than almost any annual, so protection plus a hard cutback usually gets the display back in three weeks.

Petunias are grown as annuals almost everywhere, but season length changes what you can pull off. Find your zone free with our Growing Zone Lookup before you plan the bed.

Deer and petunias: why they get eaten

Deer are selective browsers. They pick plants by smell first and texture second, and they pass on anything bitter, resinous, fuzzy, or loaded with milky sap. Petunias fail two of those tests and only half pass the third.

Low aromatic oils. Petunia foliage has a faint, slightly musky smell. It's nothing like lavender, salvia, or marigold, which flood a deer's nose and get skipped. A deer walking past a petunia basket gets almost no warning signal.

Soft, water-rich tissue. Petunia leaves and stems are thin-walled and full of water. That's exactly the mouthfeel deer prefer, and it's why hostas, impatiens, and daylilies top every "deer candy" list.

Sticky glandular hairs, the one real defense. Petunia leaves are covered in short glandular hairs that make them tacky to the touch. Those hairs do reduce feeding a little. They are why petunias sit above impatiens and pansies on browse ratings instead of at the very bottom, though pansies still earn their place in an autumn planter that holds to frost.

Rutgers New Jersey Agricultural Experiment Station keeps the ratings most nursery tags borrow from, and its Landscape Plants Rated by Deer Resistance list puts petunias in the middle band, the one described as occasionally severely damaged. That's a fair description. In a light-pressure yard you may go a whole summer untouched. In a yard on a deer route, a full basket disappears in one night.

Here's the honest ranking of petunias against their shelf neighbors.

What deer damage on petunias actually looks like

Half the emails about deer turn out to be rabbits, slugs, or budworm. Diagnose before you spend money on the wrong fix.

Deer have no upper front teeth. They grip a plant and tear, so the break is ragged and stringy. Rabbits have sharp incisors and leave a clean cut at a 45 degree angle, like scissors.

Deer damage on petunias has a signature: the plant looks decapitated. The flowers and the top two inches are gone, the lower foliage sits there untouched, and there's a hoof print in the mulch. Rabbits do the opposite and work from the bottom up.

Which petunias get hit hardest

Not all petunias are equally attractive, and the differences are big enough to change what you buy.

Spreading and Wave types are the worst. Wave, Easy Wave, and Supertunia varieties push out huge amounts of soft new growth and carry flowers across the whole surface. Deer shear them flat like a hedge trimmer. The plant recovers, but the display is gone for two to three weeks.

Grandifloras are the second target. Big single blooms, four inches across, sitting up high on soft stems. They are the most visible flower in the bed and the easiest single bite.

Multifloras and millifloras hold up best. Smaller flowers, tougher stems, more of them. A deer takes a mouthful and gets less of the plant, and the loss is far less visible because there are 40 blooms rather than 12.

Calibrachoa is the safer swap. Million bells is a close relative with smaller, tougher leaves and a denser habit. It gets browsed noticeably less than petunias, though it is still not in the top tier of resistant annuals. It's the right choice for mixed containers you can't protect.

When deer pressure on petunias peaks

Browsing is not steady across the season. Knowing the spikes tells you when to be diligent with repellent.

The planting-week spike surprises people. A petunia straight from a greenhouse has been watered daily, fertilized hard, and grown under shade cloth, so its tissue is softer and its scent weaker than a plant that has spent a month in full sun. Spray repellent on planting day, before the first bite, not after. Deer form route habits fast, and a container they have fed from once becomes a scheduled stop.

How to grow petunias anyway: seven fixes, ranked

You do not have to give up petunias. You do have to pick a defense and commit to it.

1. Height, the free fix. Deer feed comfortably from ground level to about 6 feet, but they will not stretch upward into an unstable position for a low-value plant. Hanging baskets at 6.5 feet or higher, and window boxes on a second story, are effectively safe. Baskets at 5 feet on a shepherd's hook are not.

2. Repellent, rotated. This is the workhorse. Egg-solids sprays work by smell and are the most reliable class. Rotate between two or three different active ingredients every 4 to 6 weeks, because deer habituate to a single scent within about a month.

Spray on a dry day above 45°F, coat new growth (that's what gets eaten), and reapply every time the plant grows an inch of fresh tips.

3. Containers on a deck or porch. Deer avoid enclosed spaces with a single exit and unfamiliar footing. A pot on a raised deck with railings gets browsed far less than the identical pot on the lawn 12 feet away. Our container gardening guide has the potting mix and watering specifics for petunias in pots.

4. Motion-activated sprinklers. Genuinely effective, and each one covers about 1,000 square feet. They cost more than a season of repellent but less than fencing, and they last for years. They work best as a surprise, so move them every couple of weeks. They also stop working the day you drain the hose for winter.

5. Fishing line at 3 feet. A single strand of 30-pound monofilament strung on stakes at chest height for a deer. They walk into something they can't see, spook, and reroute. It's cheap and startlingly effective on small beds, though it fails once the herd learns the yard.

6. Real fencing. The only method that works every night without maintenance. Deer clear 6 feet easily. An 8-foot fence stops them, and two parallel 4-foot fences set 4 feet apart also work, because deer judge depth poorly and won't jump into a narrow landing.

7. Placement strategy. Put petunias where you already have coverage: inside a fenced patio, against the house behind resistant plants, in the pot by the front door where people come and go. Put lantana, angelonia, and dusty miller on the perimeter where deer arrive first. Our deer resistant flowers list is organized this way.

Worked example: a 24-foot porch rail in a deer corridor

A real decision, worked through with quantities and labor rather than a shopping receipt, so it holds up wherever you garden.

The setup: six window boxes along a 24-foot porch rail, three Wave petunias per box, 18 plants total, at 42 inches off the ground. Suburban lot backing onto woods, with deer through the yard nearly every night. Last year the boxes were stripped twice, in mid-June and again in late August.

Option A, replant and hope. Buy 18 plants, watch them go, buy 18 more. Two full sets of plants in one season, plus two ruined displays and six weeks of bare boxes in peak porch season. This is what happened last year, and it is by a wide margin the most expensive of the three.

Option B, repellent rotation. Two quart concentrates, one egg-solids and one garlic-based, each making roughly 4 gallons of spray. Alternate them: spray on planting day, then every 4 weeks and after every heavy rain. That works out to about 8 applications from May through September at roughly 12 minutes each, so a little under two hours of work across the whole season, and one pair of concentrates covers it with spray left over. Cheaper than a single replant, let alone two.

Option C, raise the boxes. Move the display to hanging baskets on 7-foot brackets, six brackets, bought once and reused every year afterward. It costs more up front than a season of repellent and nothing at all thereafter. Baskets dry out faster, so add a daily watering habit in July and August.

What actually worked: B plus a partial C. Four boxes stayed on the rail with rotated repellent, and the two boxes at the corner nearest the woods, where damage started both times, got swapped for lantana and dusty miller. One season of repellent, six replacement plants rather than thirty-six, and zero stripped displays.

The lesson is that the cheapest fix is usually not a product. It's moving the two plants sitting in the deer's path. Before you buy anything, stand at the corner of the yard the deer enter from and look at which containers they reach first. Those are the ones to plant with something they don't want.

Deer resistant swaps that look like petunias

If you're tired of the fight, these give you the same job in the same spot.

A perimeter of aromatic perennials helps too. Lavender is one of the most reliable scent barriers you can plant, and our guide on is lavender deer resistant covers how to actually keep it alive.

Bringing browsed petunias back

Petunias respond to damage the same way they respond to pinching, which is why recovery is fast.

1. Cut everything back by one third. Do it within a day or two of the damage. Ragged torn stems invite disease and won't rebranch cleanly, so make real cuts just above a leaf node.
2. Feed with a balanced liquid fertilizer at half strength. Petunias are heavy feeders and a browsed plant is rebuilding tissue. Repeat in 10 days.
3. Water consistently. A stressed plant with dry roots stalls instead of rebranching.
4. Spray repellent the same day. Fresh regrowth is the softest, most attractive tissue on the plant, and the deer already know where it is.
5. Expect flowers again in 14 to 21 days. Multifloras come back fastest, Waves take the longest because there is more of them to rebuild.

Frequently asked questions

Are petunias deer resistant at all?

Only slightly. The sticky glandular hairs on the leaves put petunias above impatiens and pansies, but they sit in the middle band of every resistance rating, meaning occasionally severely damaged. In a yard with real deer traffic, treat them as vulnerable.

Will deer eat petunias in pots and hanging baskets?

Yes, if they can reach them. A pot on the ground or a basket at 5 feet is fair game. Baskets hung at 6.5 feet or higher are effectively out of reach, since deer won't stretch upward into an unstable position for a low-value plant.

Do deer eat petunia flowers or the whole plant?

Flowers and buds first, then soft stem tips, and the older lower foliage last. That's why browsed petunias look decapitated rather than eaten. Under heavy pressure, especially in late summer, they will take the whole plant down to the crown.

Are Wave petunias more deer resistant than regular petunias?

No, they're less. Wave and other spreading types produce a large surface of soft new growth and flowers, which makes them a bigger, easier meal. Multiflora and milliflora types hold up better because their stems are tougher and each bite costs you less of the display.

What smell keeps deer away from petunias?

Putrescent egg solids are the most consistently effective repellent scent, followed by garlic and clove oil blends. Rotate at least two different products every 4 to 6 weeks, because deer habituate to a single smell within about a month.

Will marigolds planted around petunias protect them?

Not reliably. Companion planting for deer control mostly fails, because deer feed by walking through a bed and taking what they want, not by avoiding an entire area over one scent. A resistant plant protects itself, not its neighbors.

Do deer eat calibrachoa (million bells) too?

Less often. Calibrachoa has smaller, tougher leaves and a denser habit, so it gets browsed noticeably less than petunias. It's still not in the top resistant tier, so treat it as a better bet rather than a solution.

Will my petunias recover after deer eat them?

Almost always, and quickly. Cut the plant back by a third, feed at half strength, water consistently, and spray repellent the same day. Most petunias are blooming again in two to three weeks.

The short version

Deer eat petunias, mostly the flowers, and no petunia variety is deer proof. Sticky leaf hairs give them a small edge over impatiens and pansies, and that's the whole defense the plant brings.

Keep petunias where deer can't comfortably reach them, spray a rotated repellent starting on planting day rather than after the first bite, and move the plants in the deer's path to lantana, angelonia, or dusty miller.
