When faced with an emergency evacuation—whether due to natural disasters like hurricanes, wildfires, or severe storms—one of the critical yet often overlooked tasks is securing outdoor garden structures. These structures, which can range from sheds and greenhouses to pergolas and fences, are vulnerable to high winds, flying debris, and other hazards that may cause damage or loss. Properly securing these elements not only protects your property but also minimizes potential hazards to neighbors and emergency responders.

This article provides comprehensive tips for safeguarding your outdoor garden structures before you evacuate, helping you reduce damage and ensure a safer return after the emergency has passed.

Understand Your Garden Structures

Before diving into the securing process, take time to assess the types of garden structures on your property. Understanding how each is constructed and their vulnerabilities will help you prioritize your efforts.

  • Sheds: Often made of wood, metal, or plastic. They may have doors, windows, or loose panels.
  • Greenhouses: Typically glass or polycarbonate panels held by metal or wooden frames.
  • Pergolas and Gazebos: Usually wooden or metal framed with open sides.
  • Fences: Can be wood, vinyl, metal, or chain-link.
  • Arbors and Trellises: Lightweight wooden or metal structures.
  • Garden Furniture and Accessories: Including benches, pots, birdbaths, and statues.

Each structure has unique weak points that need attention before storms or high winds.

General Preparation Before Evacuation

1. Create an Inventory

Document all outdoor garden structures with photos and notes about their condition. This inventory will assist with insurance claims if damage occurs during the emergency.

2. Review Local Emergency Guidelines

Some communities have specific ordinances about securing loose outdoor items during storms. Check whether tarp restrictions or debris rules affect your preparations.

3. Gather Necessary Tools and Materials

Stockpile materials such as:

  • Heavy-duty tarps
  • Bungee cords, straps, or ratchet tie-downs
  • Rope
  • Sandbags
  • Plywood sheets
  • Nails and screws
  • Anchors or ground stakes
  • Plastic wrap for greenhouses

Having these ready saves time when you must act quickly.

Securing Specific Garden Structures

Sheds

Sheds are often the most vulnerable because of their size and content. Here’s how to secure them effectively:

  • Lock Doors and Windows: Use sturdy locks to prevent wind from opening them.
  • Reinforce Doors: Add extra bracing or board up doors if heavy winds are expected.
  • Anchor the Shed: Ensure the shed is anchored to a concrete slab or the ground securely. If not anchored, consider adding anchors or ground stakes.
  • Remove Loose Items Inside: Store tools, pots, and other items inside heavy containers to prevent them becoming projectiles.
  • Cover Windows: Use plywood sheets nailed over windows or heavy-duty plastic sheeting taped securely.

Greenhouses

Greenhouses are fragile due to glass panels and lightweight frames.

  • Remove Loose Items Inside: Take out pots, trays, gardening tools, and anything that could break glass if displaced.
  • Secure Panels: Check the frame for loose panels; nail down or tape loose edges firmly.
  • Cover with Tarps: For additional protection against hail or flying debris, cover the entire structure with a heavy-duty tarp tied down securely.
  • Close Vents and Doors: Prevent wind from catching inside and causing structural damage.

Pergolas and Gazebos

These semi-open structures can catch strong winds easily.

  • Remove Canopies and Curtains: These can act like sails in wind.
  • Tie Down Loose Parts: Use ropes or straps to secure any loose beams or decorative elements.
  • Anchor Supports: If possible, use additional ground anchors to strengthen posts against uplift forces.
  • Remove Lightweight Furniture: Move chairs, tables, cushions indoors.

Fences

Fences can break or become debris if not maintained properly.

  • Inspect for Weaknesses: Repair loose boards or posts before evacuation.
  • Remove Hanging Items: Take down hanging plants or decorations that can be torn off by wind.
  • Add Support Braces: Temporary braces added diagonally can improve stability for older fences.

Arbors and Trellises

These delicate structures can be toppled by strong gusts.

  • Secure Base Anchors: Ensure bases are firmly anchored into the ground.
  • Remove Climbing Plants Temporarily: Heavy foliage adds wind resistance—consider trimming back if time allows.

Garden Furniture & Accessories

Small items scattered around your garden can become dangerous projectiles in extreme weather.

  • Store Indoors When Possible: Bring lightweight furniture such as plastic chairs inside.
  • Tie Down Larger Items: Use straps to anchor benches or heavy pots securely.
  • Stack Loose Items: Group pots and smaller accessories into larger containers to reduce movement.

Using Sandbags and Ground Anchors

In flood-prone areas where evacuation is necessary due to rising water, sandbags can protect both your garden structures and your home’s foundation:

  1. Place sandbags around shed door thresholds to prevent water ingress.
  2. Anchor ground stakes around lightweight structures for additional stability against flooding currents.
  3. Stack sandbags near vulnerable areas as a temporary barrier against mudslides in hilly gardens.

Protecting Plants Associated With Structures

Many outdoor structures support plants such as vines on trellises or potted plants in greenhouses.

  • Before evacuating:
  • Prune branches that could snap under heavy wind stress.
  • Secure climbing vines with extra ties so they don’t cause structural damage if blown around.
  • Relocate potted plants indoors when feasible.

Healthy plants also contribute to overall structure stability by reducing wind flow through open areas near buildings.

Post-Evacuation Considerations

Even after securing everything properly beforehand, nature’s force can still cause damage. Upon returning:

  1. Inspect all garden structures carefully before re-entering enclosed spaces like sheds.
  2. Assess any fallen trees or debris around your garden that might interfere with safe access.
  3. Document new damages immediately for insurance purposes.
  4. Plan repairs systematically rather than rushing into unstable structures too quickly.

Final Thoughts: Prioritize Safety Over Property

While protecting your garden structures is important, never compromise personal safety when evacuating. Your life always takes precedence over material possessions. Follow official evacuation orders promptly while using these tips as a guideline to mitigate potential property loss when time allows.

Securing outdoor garden structures before evacuating requires preparation, quick action, and knowledge of each structure’s unique needs. By implementing these strategies ahead of emergencies, homeowners can minimize damage to their gardens and enjoy peace of mind during stressful times.


By planning ahead with these practical tips in mind, you ensure that your beautiful outdoor spaces remain intact—or at least salvageable—after any natural disaster forces you from your home temporarily. Properly secured gardens return quicker to being places of refuge and joy once emergencies subside.
