Do Deer Eat Geraniums?

Updated September 2026 · Garden Advice Guide

Mostly no. Geraniums are one of the more reliable choices in deer country, and both plants sold under the name qualify: annual bedding geraniums (Pelargonium) carry thick, fuzzy, strongly scented leaves, and hardy geraniums or cranesbills (true Geranium) carry aromatic foliage with a bitter edge. Deer walk past both in a normal year. So the practical answer to do deer eat geraniums is that they sample them, occasionally strip the flowers, and almost never destroy the plant.

The exceptions are worth knowing, because they are predictable: brand new transplants, deep drought, late winter when nothing else is green, and high-density suburban herds that have already eaten the good stuff.

Two different plants, one confusing name

This trips up every deer-resistance list, because the two plants are not closely related and they behave differently in the garden.

Both hold up well. The hardy ones hold up slightly better, and one of them, bigroot geranium, is close to the top of any honest resistant list.

Why deer usually skip geraniums

Deer eat with their noses first. A plant gets rejected before the first bite far more often than after it.

Volatile oils. Crush a zonal geranium leaf and the smell is immediate and strong. Scented geraniums take that to an extreme, which is why rose, lemon and peppermint scented types are among the least browsed plants you can put in a pot. That scent also masks the smell of anything planted behind it, which is a real design tool.

Fuzzy, thick texture. Deer prefer soft, water-rich, hairless leaves. Hosta, impatiens and daylily are the profile they love. A zonal geranium leaf is the opposite: thick, velvety, and unpleasant in the mouth.

Bitter compounds. Hardy geraniums contain tannins that make the foliage astringent. It is not toxic, it just tastes bad, and a deer with better options nearby takes the better option.

Low food value. A geranium is not a lot of calories for the effort. Deer are efficient and they browse where the return is high, which is why they hit a hosta bed and walk past a border of cranesbill on the way.

Rutgers publishes the rating scale that most garden centers quote, running from rarely damaged through frequently severely damaged. Geraniums of both kinds sit in the second band, seldom severely damaged, which is where you want a plant to sit if you have deer but do not want a fence.

Do deer eat geraniums in a bad year?

Yes, sometimes, and the pattern is consistent enough to plan around. Here's when the rule breaks.

Late winter and very early spring. February through April is the hungriest stretch of the deer year. Fat reserves are gone, forage is not up yet, and anything green gets tested. Early hardy geranium foliage is one of the first green things in a shady border, and it gets sampled.

The first two weeks after planting. Nursery plants come out of a greenhouse pumped full of nitrogen and water. Those leaves are softer, sweeter and much more appealing than the same plant six weeks later. Almost every "but it was supposed to be deer resistant" story starts with a plant that had been in the ground for four days.

Drought. A thirsty deer eats for moisture, not for flavor. In a serious dry spell, plants that were ignored all June start losing leaf tips.

Flowers before foliage. Even where deer leave the leaves alone, they will nip flower heads off zonal geraniums, especially at nose height in a raised planter. The plant survives easily. The display does not.

Containers on decks and porches. This surprises people. A pot of geraniums on a step is at exactly the right height, it smells of water and fertilizer, and a deer that already walks your patio has no reason not to try it.

Very high deer density. In neighborhoods where the herd is large and the browse line on the trees is obvious, no list holds. Resistance is a ranking, not a guarantee.

Which geraniums hold up best

Not all of them are equal. If deer pressure is the deciding factor, the ranking below is the one to plant by.

Bigroot geranium is the one to reach for in a genuinely bad deer area. It is aromatic enough that deer avoid the ground around it, it spreads into a weed-smothering mat, it takes dry shade under trees, and it stays semi-evergreen in the warmer half of its range. Our deer resistant ground cover guide covers how to use it as a living mulch under shrubs.

If you want the long bloom of 'Rozanne', plant it, but plant it behind something tougher rather than at the front edge where a passing deer meets it first.

Telling deer damage from everything else

Get the diagnosis right before you buy a repellent, because rabbits, slugs and groundhogs all take geraniums and none of them respond to the same fix.

Deer have no upper front teeth. They grip and tear, which is why the break is always ragged. That single detail settles most arguments.

Worked example: replanting a 24-foot front border with deer pressure

Here's a real layout problem solved with geraniums doing the heavy lifting.

The bed is 24 feet long and 4 feet deep, facing east, in zone 6. Deer cut through the yard nightly. The previous planting was hosta and daylily, which is deer candy, and it was stripped to stubs by mid June two years running.

Step 1, count the space. At 24 feet by 4 feet, that is 96 square feet of bed.

Step 2, front edge, 24 running feet. Bigroot geranium at 18 inch spacing needs 16 plants. It will close into a continuous mat by the second season and it is the layer deer meet first.

Step 3, middle band. Twelve catmint at 24 inch spacing, another strongly aromatic plant, running the length of the bed behind the geraniums.

Step 4, back layer. Six ornamental grasses at 36 inch spacing. Deer do not eat grasses, and the height gives the bed structure through winter.

Step 5, seasonal color. Six zonal geraniums in two large containers flanking the walk, replanted each spring, plus two scented geraniums tucked at the ends of the border where people brush past them.

Step 6, the first three weeks. Every new plant gets a repellent spray on planting day and again on day 7 and day 14. After that, stop. The plants have hardened off and the scent chemistry has caught up.

Result. Total plant count is 40 in the ground plus 8 in pots. Nothing in the bed is on the deer candy list, the three most aromatic species are on the outside edge where they act as a scent screen, and the only ongoing task is three sprays in spring.

For a longer list of what else belongs in that middle band, our deer resistant perennials guide sorts by zone and sun, and deer resistant annuals covers the container layer. If you are trying to work out what pulled the deer in to begin with, plants deer love is the honest list.

Protecting geraniums during the risky windows

You do not need a year-round program. You need coverage during four short stretches.

1. Planting day through week three. Spray a repellent on the day you plant, then again at day 7 and day 14. This is the highest-value spraying you will ever do.
2. Late winter into early spring. One or two applications as the first hardy geranium foliage pushes up, before the wild browse greens up.
3. Any serious drought. Deer widen their diet when they are thirsty. Watering the garden well actually reduces browsing a little, since stressed plants concentrate sugars.
4. After heavy rain. Contact repellents wash off. Reapply after a downpour rather than on a fixed schedule.

Rotate products. Deer habituate to a single smell within a few weeks. Alternating between an egg-solids based repellent and a capsaicin or garlic based one keeps the response fresh.

Height beats scent for containers. A pot on a 3-foot pedestal is a genuinely harder target than the same pot on a step. So is a hanging basket.

Fencing is the only guarantee. Nothing on this page is a substitute for an 8-foot fence if the pressure is severe. Resistant planting is what you do instead of a fence, not alongside a broken one.

For shade beds where geraniums are already the best available choice, our deer resistant shade plants guide lists what to pair them with under trees.

Are geraniums safe around deer and other animals?

Geraniums are not toxic to deer, which is worth saying because people assume resistance implies poison. It does not. The plants are simply unpleasant to eat.

Pelargonium is mildly toxic to dogs and cats, causing stomach upset and skin irritation, so keep pots off the ground if you have a chewer. The sap sits in roughly the same low risk band as the milky sap in a poinsettia bract. True Geranium species are considered non toxic and appear on the safe lists used in family-friendly plantings.

There is one persistent myth worth clearing up: geraniums do paralyze Japanese beetles that feed on the flowers, but only for a few hours, which makes it a fun demonstration rather than a control method. Our Japanese beetle guide covers what actually works.

Zone matters as much as deer resistance for anything you want back next spring. The USDA's plant hardiness zone map is the reference behind the zone numbers in the table above.

Frequently asked questions

Are geraniums deer resistant enough to plant with no protection?

In moderate deer pressure, yes, once they are established. Give any new planting three weeks of repellent while the nursery-soft growth hardens off, then leave them alone. In severe pressure with a visible browse line on your trees, expect occasional flower loss even on established plants.

Do deer eat hardy geraniums or just the annual kind?

They sample both, and hardy geraniums slightly less. Bigroot geranium is the most reliably ignored of the whole group because of the resin in its leaves, while softer-leaved hybrids like 'Rozanne' get tested more often. Neither is usually destroyed.

Will deer eat potted geraniums on a deck?

More often than people expect. A pot at railing height, freshly watered and freshly fertilized, is easy and appealing, and a deer already comfortable on your patio has no reason to skip it. Raise the pots, use hanging baskets, or plant the scented types in the containers closest to the steps.

Do scented geraniums repel deer from nearby plants?

They help, and the effect is real but local. A strongly aromatic plant masks the scent of what sits directly behind it, which is why an aromatic front edge protects the middle of a bed better than the same plants scattered through it. It is a screen, not a force field.

What eats geranium flowers but leaves the leaves alone?

Usually deer taking buds and open flowers at nose height, or earwigs and slugs chewing petals overnight. Check the cut edge: torn and ragged points to deer, small ragged holes with slime trails point to slugs. Our slug guide covers the second case.

Which geranium should I plant if deer pressure is severe?

Bigroot geranium, Geranium macrorrhizum, in the ground, and scented geraniums in pots. Both are at the top of the resistance ranking and both are tough plants regardless of deer, taking dry shade and neglect better than most perennials.

Do deer eat geranium seedlings and cuttings?

Young plants of any species are far more appealing than mature ones, so yes, treat them the way you would treat any transplant. Cover or spray them until the foliage toughens up, which normally takes two to three weeks in the ground.

The short version

Deer rarely eat geraniums, and the ones they eat least are bigroot geranium in the ground and scented geraniums in pots. Expect sampling in late winter, during drought, and in the first two weeks after planting, plus the occasional flower head taken off a container at nose height. Three well-timed repellent sprays in spring cover nearly all of the real risk.
