Will Deer Eat Corn Plants?

Will Deer Eat Corn Plants? The Truth Revealed

Yes, deer will indeed eat corn plants. In fact, corn is considered one of their preferred food sources, especially during certain times of the year, making it a significant concern for farmers and gardeners, and resulting in substantial crop damage.

Corn: A Deer’s Delight

Deer are opportunistic herbivores, and their diet varies depending on availability and season. Corn plants, particularly young, tender shoots, are a highly attractive food source. Understanding why corn appeals to deer and the extent of the potential damage is crucial for implementing effective prevention strategies.

Why Deer Love Corn

Several factors contribute to corn’s appeal to deer:

  • Nutritional Value: Corn is rich in carbohydrates, providing deer with a valuable energy source, especially during the late summer and fall as they prepare for winter.
  • Palatability: Young corn plants are tender and palatable, making them easy for deer to consume.
  • Accessibility: Cornfields are often easily accessible to deer, offering a readily available and abundant food supply.
  • Seasonal Availability: Corn is particularly attractive to deer during periods when other food sources are scarce or less nutritious, such as early spring when new growth emerges and late summer/early fall before other forage matures.

Stages of Corn Vulnerability

Deer are likely to target corn plants at different stages of development:

  • Early Seedling Stage: Young, tender shoots are highly susceptible to deer browsing. The entire plant may be consumed, preventing further growth.
  • Vegetative Growth Stage: As corn plants mature, deer may continue to browse on the leaves, stunting growth and impacting yield.
  • Ear Development Stage: Deer may target developing corn ears, leading to direct yield losses. They may also damage the stalks while attempting to reach the ears.

The Impact of Deer on Corn Crops

Deer browsing can have significant economic impacts on corn crops:

  • Reduced Yield: Deer consumption can significantly reduce the overall yield of corn crops.
  • Stunted Growth: Browsing on young plants can stunt their growth, delaying maturity and reducing the potential yield.
  • Plant Death: Severe browsing can kill young corn plants, requiring replanting.
  • Increased Costs: Farmers may incur additional costs for implementing deer control measures, such as fencing, repellents, or hunting permits.

Preventing Deer Damage: Effective Strategies

A combination of strategies is often necessary to effectively prevent deer damage to corn crops:

  • Fencing: Installing a physical barrier, such as a woven wire fence or electric fence, is one of the most effective methods of deterring deer. Height is critical; fences should be at least 8 feet tall.
  • Repellents: Deer repellents, available in liquid or granular form, can deter deer from browsing on corn plants. These often work by emitting an unpleasant odor or taste.
    • Scent-based repellents: Mimic predator urine or other unpleasant scents.
    • Taste-based repellents: Make the plants taste bitter or unpleasant.
  • Motion-Activated Sprinklers: These devices detect movement and spray water, scaring deer away from the area.
  • Hunting: Where permitted, regulated hunting can help control deer populations and reduce browsing pressure on corn crops.
  • Crop Rotation: Rotating corn crops with less desirable food sources may help reduce deer browsing pressure.
  • Companion Planting: Some plants, such as marigolds and garlic, are thought to deter deer and can be planted alongside corn.

Understanding Deer Behavior

Understanding deer behavior is crucial for developing effective prevention strategies. Deer are creatures of habit and tend to follow the same routes and feeding patterns. By identifying these patterns, farmers and gardeners can strategically implement control measures to protect their corn crops.

Frequently Asked Questions (FAQs)

What time of year are deer most likely to eat corn plants?

Deer are most likely to eat corn plants during early spring, when young shoots emerge, and during late summer/early fall as they prepare for winter and corn is ripening. These are times when other food sources may be scarce or less nutritious.

Are some varieties of corn more susceptible to deer damage than others?

While research on specific corn varieties is limited, it’s generally believed that all corn varieties are susceptible to deer damage, particularly at young stages. However, taller varieties may be slightly less attractive to deer than shorter ones.

How high does a fence need to be to keep deer out of my cornfield?

A fence needs to be at least 8 feet tall to effectively deter deer. Deer are capable of jumping surprisingly high, and anything shorter than 8 feet may not prevent them from entering the field.

Are there any natural predators that can help control deer populations and reduce corn damage?

While natural predators such as wolves and coyotes can help control deer populations in some areas, their impact on corn damage is often limited. The best approach involves a multifaceted strategy that includes fencing, repellents, and, where permitted, hunting.

Do deer only eat the leaves of the corn plant, or do they also eat the ears?

Deer will eat both the leaves and the ears of corn plants. During the early stages of growth, they primarily browse on the leaves. As the corn develops ears, deer will target these, often damaging the stalks in the process.

How effective are deer repellents, and how often do I need to reapply them?

Deer repellents can be moderately effective, but their efficacy depends on several factors, including the specific product used, the deer population in the area, and weather conditions. Reapplication is crucial, especially after rain or heavy dew, typically every few weeks or as directed by the product label.

Will scarecrows deter deer from eating my corn?

Scarecrows may provide a temporary deterrent, but deer are intelligent animals and quickly learn that they pose no real threat. They are not a reliable long-term solution for preventing deer damage to corn crops.

Can I use dogs to keep deer away from my cornfield?

Dogs can be effective at deterring deer, but it requires consistent training and management. The dog needs to be reliably trained to chase deer away without harming them and must be supervised to prevent them from damaging the cornfield themselves.

What are some cost-effective ways to protect a small corn patch from deer?

For small corn patches, a combination of strategies is often the most cost-effective approach. Consider using a lower-cost deer repellent, surrounding the patch with temporary fencing made of netting or chicken wire, and using motion-activated sprinklers.

Is it legal to hunt deer in my area to protect my corn crops?

Regulations regarding deer hunting vary significantly by location. It’s essential to check with your local wildlife agency to determine the legality of hunting deer on your property and to obtain any necessary permits or licenses.

Are there any plants I can grow around my corn to deter deer?

Some plants are believed to have deer-repellent properties, including marigolds, garlic, and onions. While they may offer some limited protection, they are not a guaranteed solution and should be used in conjunction with other deer control methods.

What should I do if deer have already severely damaged my corn crop?

If deer have severely damaged your corn crop, the best course of action depends on the stage of growth. If the plants are young, you may need to replant. Implement immediate deer control measures, such as fencing or repellents, to prevent further damage. For older plants, focus on protecting the remaining crop to salvage what you can.
