Deer eating your carefully tended plants is infuriating. After another morning discovering devastated roses or stripped hostas, you want solutions—not sympathy.

Here’s a practical guide to the options available, from quick fixes to permanent solutions.

Understanding the Challenge

Before choosing a method, be realistic about what you’re dealing with:

• Deer are persistent: A hungry deer will try repeatedly to access food
• Deer are adaptable: They learn to overcome obstacles and ignore deterrents
• Numbers matter: In high-density areas like Ashdown Forest, exclusion becomes increasingly difficult
• No single solution is perfect: Most successful approaches combine multiple methods

Option 1: Fencing

The most reliable method of excluding deer—if done properly.

Requirements for Effective Deer Fencing

Height: Minimum 1.8m (6ft) for fallow deer; roe deer can sometimes be excluded with 1.5m

No gaps: Deer will push through surprisingly small openings. The fence must be continuous with no weak points.

Sturdy construction: Deer will lean on fences, push against them, and test weak points

Gates: Often the weak link. Must be as tall and secure as the fence itself.

Fencing Types

Cost Reality

For a typical large garden (say, 0.5 acres), expect:

• Basic deer netting: £1,500-3,000+ including installation
• Stock fencing to deer height: £3,000-6,000+
• Electric fencing: £1,000-2,500+ plus ongoing costs

For larger properties, costs escalate quickly—and often become impractical.

When Fencing Makes Sense

• Small, high-value areas (vegetable gardens, orchards)
• Properties where you need guaranteed exclusion
• Where budget allows for proper installation
• When combined with population management

When Fencing Doesn’t Make Sense

• Very large areas
• Properties with multiple access points
• Where deer pressure is extreme (they’ll find weaknesses)
• As the only solution in high-density areas

Option 2: Repellents

Repellents work by making plants taste bad or creating unpleasant smells. They’re readily available but have significant limitations.

Types of Repellent

Scent-based: Products containing predator urine, blood meal, or putrid egg. Create an odour deer dislike.

Taste-based: Bitter-tasting sprays applied to plants. Deer learn to avoid treated vegetation.

Physical: Capsaicin (chilli) based products that irritate the mouth.

Effectiveness

Repellents can provide temporary relief but:

• Must be reapplied frequently (after rain, new growth)
• Deer can habituate to them over time
• Less effective when deer are hungry
• Don’t work at all in areas of very high deer pressure
• Annual cost adds up

Best Use

Repellents work best:

• On specific high-value plants
• As a short-term measure while implementing other solutions
• In areas of moderate deer pressure
• Combined with other methods

Option 3: Plant Selection

Choosing plants that deer find less palatable can reduce damage—though no plant is truly “deer-proof” when animals are hungry enough.

Plants Deer Generally Avoid

Strong scents: Lavender, rosemary, sage, mint, thyme

Toxic plants: Foxgloves, hellebores, euphorbias, daffodils (caution with pets/children)

Prickly/tough: Holly, berberis, pyracantha, ornamental grasses

Strong flavours: Alliums, fennel, artemisia

Plants Deer Love (Avoid These)

• Roses
• Hostas
• Tulips
• Fruit trees
• Most vegetables
• Pansies, petunias, impatiens
• Hydrangeas

Limitations

In areas with high deer populations:

• Even “deer-resistant” plants get eaten
• Deer browse on whatever’s available when preferred food is scarce
• Young plants are more vulnerable than established ones

Option 4: Scare Devices

Motion-activated sprinklers, ultrasonic devices, and other scare tactics have limited effectiveness.

Initial success: Deer may be startled at first

Rapid habituation: They quickly learn devices pose no real threat

Best use: Only as part of a multi-method approach, and rotated frequently

Option 5: Professional Deer Management

For properties in high-density areas, reducing the local deer population is often the only practical long-term solution.

Why Population Management Works

• Addresses the root cause, not just symptoms
• Reduces pressure on fencing and other measures
• Benefits the wider ecosystem
• One-time effort (with maintenance) vs. ongoing costs

How It Works

A professional stalker:

1. Assesses deer activity on your land
2. Identifies movement patterns and access points
3. Conducts humane culling, typically at dawn
4. Returns regularly to maintain reduced numbers

What It Costs

I provide free deer management for landowners across East Sussex. There’s no charge for the service—my reward is access to stalking on your land.

Combining Approaches

The most effective strategy usually combines multiple methods:

1. Population management as the foundation—reducing overall deer numbers
2. Targeted fencing for highest-value areas (vegetable garden, young orchard)
3. Plant selection to reduce attractiveness of the wider garden
4. Repellents as a backup for specific plants during vulnerable periods

Getting Started

If deer are destroying your garden in the Ashdown Forest area or elsewhere in East Sussex:

1. Confirm you have deer – Check for signs of deer damage
2. Assess the scale – How much land? How severe the pressure?
3. Consider your priorities – What must be protected? What can you live with?
4. Choose your approach – Often a combination works best
