Do Deer Hate Geraniums? Unveiling the Truth
Deer browsing in your garden can be frustrating! This article delves into whether deer truly hate geraniums, offering insights and strategies for protecting your precious plants. The answer might surprise you, as it’s more nuanced than a simple yes or no!
Understanding Deer Preferences and Geranium Characteristics
The age-old question, Do deer hate geraniums?, often arises from the constant battle between gardeners and hungry deer populations. To understand this relationship, we need to consider deer feeding habits and the specific characteristics of geraniums.
Deer are opportunistic herbivores. Their diet depends on availability, season, and individual preference. They generally favor succulent, tender plants, especially when food is scarce. However, deer also possess a keen sense of smell and taste, which influences their choices.
Geraniums, on the other hand, are characterized by:
- Strong, often pungent, scent, especially zonal geraniums (Pelargonium x hortorum).
- Textured leaves that can be slightly fuzzy.
- Presence of oils and compounds that some animals find unpalatable.
The “Deer-Resistant” Myth and Geraniums
It’s crucial to understand that “deer-resistant” doesn’t mean “deer-proof.” No plant is entirely safe from a hungry deer. When other food sources are depleted, deer may sample even those plants they typically avoid. The term “deer-resistant” simply means that deer are less likely to browse on them compared to other, more appealing plants.
Geraniums are generally considered deer-resistant, especially the zonal geranium varieties. Their strong scent seems to deter deer in many cases. However, several factors influence whether or not deer hate geraniums enough to leave them alone.
Factors Influencing Deer Browsing on Geraniums
Several variables can influence whether deer will browse on your geraniums:
- Deer Population Density: In areas with high deer populations, competition for food increases, and deer may become less picky.
- Availability of Alternative Food Sources: If other food sources are scarce, deer may be more likely to try geraniums, even if they aren’t their first choice.
- Geranium Variety: While zonal geraniums are often considered deer-resistant, ivy geraniums (Pelargonium peltatum) may be more appealing to deer due to their less pungent scent and softer foliage.
- Location and Environment: Geraniums planted near deer trails or in areas with heavy deer traffic are at higher risk.
- Individual Deer Preferences: Just like humans, deer have individual preferences. What one deer avoids, another might sample.
Strategies to Protect Geraniums from Deer
Even if deer hate geraniums in theory, you might still need to take proactive measures to protect your plants:
- Physical Barriers: Fencing (even a low fence can be effective), netting, or cages can physically prevent deer from accessing your geraniums.
- Repellents: Deer repellents, both commercially available and homemade (e.g., using egg-based sprays), can deter deer with their scent or taste. Reapply after rain.
- Companion Planting: Plant geraniums near other deer-resistant plants with strong scents, such as lavender, rosemary, or marigolds.
- Motion-Activated Sprinklers: These devices startle deer with a sudden burst of water, discouraging them from entering your garden.
- Guard Animals: Dogs or other guard animals can deter deer from approaching your property.
- Strategic Placement: Plant geraniums closer to your house or in areas that are less accessible to deer.
- Offering Alternative Food Sources: Providing supplemental feeding for deer in a different part of your yard might divert their attention away from your geraniums. However, be aware that this can also attract more deer to your property overall.
Types of Geraniums and Deer Resistance
Here’s a quick breakdown of different geranium types and their general deer resistance:
| Geranium Type | Deer Resistance Level (General) | Notes |
|---|---|---|
| ———————— | ——————————- | ———————————————————————————————————————————— |
| Zonal Geraniums | High | Strong scent and textured leaves are generally unappealing. |
| Ivy Geraniums | Moderate to Low | Softer leaves and less pungent scent may make them more attractive to deer. |
| Scented Geraniums | Moderate to High | Deer resistance varies depending on the specific scent (e.g., lemon, rose). Stronger scents are generally more effective. |
| Martha Washington Geraniums | Moderate | Larger flowers and slightly less pungent foliage may make them somewhat more susceptible compared to zonal types. |
Frequently Asked Questions About Deer and Geraniums
Do deer hate geraniums? Here are some frequently asked questions and their answers:
Are geraniums poisonous to deer?
No, geraniums are not generally considered poisonous to deer. While they contain compounds that may make them unpalatable, they are not toxic. Deer are more likely to avoid geraniums due to their scent and texture rather than a fear of poisoning.
Will deer eat all types of geraniums equally?
No. As noted earlier, zonal geraniums are generally considered more deer-resistant than ivy geraniums. Scented geraniums also offer varying levels of resistance depending on their specific fragrance.
What is the best way to protect geraniums from deer browsing?
Combining multiple strategies is often the most effective approach. This might include physical barriers, repellents, and companion planting. Rotating repellents can also help prevent deer from becoming accustomed to a specific scent.
Do homemade deer repellents work on geraniums?
Yes, some homemade deer repellents can be effective. Egg-based sprays, garlic sprays, and soapy water sprays are common options. However, they often need to be reapplied frequently, especially after rain.
Are there any other plants that deer dislike that I can plant near my geraniums?
Yes! Excellent companion plants include: lavender, rosemary, marigolds, daffodils, and ornamental onions. These plants have strong scents or textures that deer typically avoid.
How often should I apply deer repellent to my geraniums?
The frequency of application depends on the specific repellent and weather conditions. Always follow the manufacturer’s instructions. Generally, reapply after rain or every few weeks.
Will a fence completely protect my geraniums from deer?
A fence can be very effective, but its height is important. A fence at least 6-8 feet tall is typically required to deter most deer. However, even a lower fence can be effective in some situations.
Can I use motion-activated sprinklers to keep deer away from my geraniums?
Yes, motion-activated sprinklers can be a very effective deterrent. The sudden burst of water startles deer and discourages them from entering the area.
Do deer get used to deer repellents?
Yes, deer can become accustomed to the same scent or taste over time. Rotating different types of repellents can help prevent this from happening.
What are the signs that deer are eating my geraniums?
Signs of deer browsing include: ragged or uneven edges on leaves, missing flower buds, and broken stems. You may also find deer droppings nearby.
If deer are eating my geraniums, does that mean they are starving?
Not necessarily. While starvation can make deer less picky, they may browse on geraniums even when other food sources are available, especially if the population is high and competition is fierce.
Is there a specific smell that deer hate that I can use to protect my geraniums?
Strong, pungent scents are generally effective. Garlic, peppermint, and clove oil are often used in deer repellents. The effectiveness can vary depending on the deer population and their individual preferences.
