What Arborvitae Will Deer Not Eat? Choosing Deer-Resistant Varieties
Deer are notorious for their varied appetites, and unfortunately, most arborvitae are on the menu. However, understanding specific varieties can help you choose options that are less palatable to these browsing creatures. While no arborvitae is completely deer-proof, some exhibit significant deer resistance, making them a better choice for landscapes prone to deer damage.
Understanding Deer Preferences and Arborvitae Appeal
Deer browse on a wide range of plants, but certain characteristics make some species more appealing than others. Factors like succulence, nutrient content, and availability play a role. Most arborvitae offer a readily available source of greenery, especially during winter when other food sources are scarce. Soft, new growth is particularly tempting. The question, “What arborvitae will deer not eat?” is less about complete immunity and more about relative resistance.
Factors Affecting Deer Browse
Deer feeding habits are also influenced by:
- Deer Population Density: Higher deer populations mean more pressure on available food sources.
- Habitat Availability: Scarcity of natural food sources can drive deer to browse on ornamental plants.
- Weather Conditions: Harsh winters and dry summers can increase deer browse on readily available plants like arborvitae.
- Regional Variations: Deer preferences can vary depending on the region and the availability of alternative food sources.
Arborvitae Varieties and Deer Resistance
While no arborvitae is truly deer-proof, some cultivars are considered more resistant than others. The following list showcases some varieties to consider when battling deer. Keep in mind that resistance can vary depending on the environmental factors listed above.
- ‘Green Giant’ Arborvitae: Often cited as relatively deer-resistant, particularly when mature.
- ‘Emerald Green’ Arborvitae: While not as resistant as ‘Green Giant,’ it can sometimes escape heavy browse.
- ‘Techny’ Arborvitae: Known for its hardiness, this variety can withstand more deer pressure than some others.
It’s crucial to understand that deer resistance is a spectrum. Even “deer-resistant” varieties can suffer damage under heavy deer pressure, especially when young or when alternative food sources are scarce.
Strategies to Protect Arborvitae from Deer
Choosing the right arborvitae is just one part of the solution. Implementing other deer deterrent strategies can significantly increase your success.
- Physical Barriers: Fencing is the most effective way to prevent deer browse. Consider using netting or mesh around individual plants or creating a larger enclosure.
- Deer Repellents: Commercial deer repellents are available in various forms, including sprays, granules, and electronic devices. Rotate repellents to prevent deer from becoming accustomed to them.
- Companion Planting: Surrounding arborvitae with plants deer dislike, such as fragrant herbs (lavender, rosemary), can deter deer.
- Motion-Activated Sprinklers: These devices startle deer and can discourage them from browsing in your garden.
- Provide Alternative Food Sources: While counterintuitive, providing alternative food sources, especially in winter, can reduce pressure on your ornamental plants. This can involve strategically placed deer feeders away from your prized arborvitae.
Common Mistakes in Deer Management
Many homeowners make common mistakes that reduce the effectiveness of their deer management strategies.
- Relying on a Single Method: Using only one deer deterrent method rarely provides adequate protection.
- Inconsistent Application of Repellents: Repellents must be applied regularly, especially after rain or snow.
- Neglecting Fencing Maintenance: Gaps in fencing can allow deer access to your garden.
- Ignoring Environmental Factors: Understanding local deer populations and available food sources is crucial.
- Planting Highly Palatable Plants: Planting deer favorites near less palatable species can attract deer and increase browse pressure on all plants.
| Strategy | Effectiveness | Cost | Maintenance | Considerations |
|---|---|---|---|---|
| ——————— | ——————- | ———– | ———– | —————————————————————————- |
| Fencing | High | High | Moderate | Requires installation and maintenance; can impact aesthetics. |
| Deer Repellents | Moderate to High | Moderate | High | Requires frequent reapplication; effectiveness can vary. |
| Companion Planting | Low to Moderate | Low | Low | May not provide complete protection; requires careful plant selection. |
| Motion-Activated Sprinklers | Moderate | Moderate | Low | Can be effective but requires water access and may not be suitable for all areas. |
Frequently Asked Questions (FAQs) about Deer and Arborvitae
What is the most important thing to consider when selecting arborvitae for a deer-prone area?
The most important factor is to choose varieties known for relative deer resistance, like ‘Green Giant,’ and supplement this choice with other deterrent strategies. Remember that no arborvitae is completely deer-proof, so a multi-pronged approach is crucial.
Are young arborvitae more vulnerable to deer browse?
Yes, young arborvitae are generally more vulnerable to deer browse than mature plants. Their foliage is typically softer and more tender, making it more appealing to deer. Protect young plants with fencing or netting.
How often should I apply deer repellent to my arborvitae?
The frequency of repellent application depends on the specific product and environmental conditions. Reapply after rain or snow, and generally every few weeks during periods of active deer browse. Always follow the manufacturer’s instructions.
Does the time of year affect deer browse on arborvitae?
Yes, deer browse tends to increase during the winter months when other food sources are scarce. You may need to increase your protection efforts during this time.
Will fencing completely protect my arborvitae from deer?
Fencing is the most effective way to protect arborvitae from deer, but it must be properly installed and maintained. The fence should be at least 8 feet tall to prevent deer from jumping over it. Ensure there are no gaps or openings.
Are there any natural deer repellents that I can use on my arborvitae?
Some gardeners have success with homemade repellents, such as sprays made with garlic, hot peppers, or soap flakes. However, the effectiveness of these natural repellents can vary. Commercial repellents are generally more reliable.
Can I train deer to avoid my arborvitae?
While it’s difficult to train deer, you can influence their behavior by making your landscape less attractive to them. This includes removing other plants they prefer and consistently using deterrents to create negative associations.
What is the best type of fencing for deterring deer?
The best type of fencing depends on your budget and aesthetic preferences. Woven wire or plastic mesh fencing are common choices. Choose a fence at least 8 feet tall to prevent deer from jumping over it.
How can I tell if deer are browsing on my arborvitae?
Signs of deer browse include ragged or broken branches, stripped bark, and missing foliage. Look for deer tracks and droppings near your plants.
Are some properties inherently more prone to deer damage than others?
Yes, properties located near wooded areas or deer migration routes are generally more prone to deer damage. Understanding your property’s location and deer activity in your area is crucial.
What companion plants can I use to deter deer from my arborvitae?
Plants with strong fragrances, such as lavender, rosemary, and sage, can deter deer. Thorny or prickly plants, like barberry, can also discourage deer browse.
What are the long-term solutions to reducing deer damage to arborvitae?
Long-term solutions involve integrating multiple deer deterrent strategies and adapting them as needed. This includes fencing, repellents, companion planting, and managing deer populations in your area. Remember the question: “What arborvitae will deer not eat?” is best answered through a comprehensive approach to landscape management.
