If your tomato cages and garden trellises are sitting unused after the summer growing season, don’t put them away just yet. Those simple garden structures can become some surprisingly impressive Halloween decorations with a little fabric, wire, lighting and imagination.
These projects are designed around things many gardeners already own, so you can create a spooky front yard without buying large pre-made props. Most cost around $5 to $30 if you reuse your existing cage or trellis.

1. Flip a Tomato Cage Upside Down to Make a Giant Spider
An upside-down tomato cage already has the rounded shape you need for an oversized garden spider. Add long black legs and webbing and it becomes a surprisingly convincing Halloween prop.
What You’ll Need
- 1 tomato cage
- Black pipe insulation, pool noodles or heavy wire
- Zip ties
- Artificial spider web
- Optional LED eyes
How to Make It
- Turn the tomato cage upside down.
- Create eight bendable legs and attach four on each side.
- Bend the legs downward so the spider sits low to the ground.
- Wrap a little faux webbing around the center of the cage.
- Add battery-powered red or orange lights for eyes.
- Stake the frame into the soil if the location is exposed to wind.
Estimated cost: $5–$12.
2. Turn a Tomato Cage Into a Glowing Mummy
A tomato cage mummy is one of the easiest projects in this collection and looks especially good after sunset.
What You’ll Need
- 1 tomato cage
- Cheesecloth, gauze or torn white fabric
- Foam ball or lightweight round object for the head
- Garden wire
- Battery-operated LED lights
How to Make It
- Flip the cage upside down.
- Secure the foam head to the narrow top.
- Wrap strips of gauze around the frame in different directions.
- Leave gaps so the wire structure remains visible.
- Place warm LEDs inside the cage.
- Leave loose strips around the bottom for a weathered look.
Estimated cost: $8–$18.
3. Stack Two Tomato Cages for a Towering Garden Witch
If your original tomato cage witch inspired you to go bigger, stacking two cages gives you a much taller silhouette that can become a front-yard focal point.
What You’ll Need
- 2 tomato cages
- Black fabric or an old black sheet
- Heavy garden wire
- Witch hat
- Optional broom and lights
How to Make It
- Join the two cages securely with garden wire.
- Check that the structure stands straight before decorating.
- Drape black fabric from top to bottom.
- Tie the fabric loosely around the middle to create shape.
- Add the witch hat.
- Anchor the base before adding lights or a broom.
Estimated cost: $12–$25.

4. Sculpt a Crouching Monster With Chicken Wire
This is the most advanced project in the group, but it can also create the most dramatic result. Chicken wire lets you form shoulders, ribs, arms and a hunched spine around the cage.
What You’ll Need
- Tomato cage
- Chicken wire
- Wire cutters
- Heavy gloves
- Garden wire
- Small LED lights
How to Make It
- Use the tomato cage as the monster’s torso.
- Bend chicken wire over it to create shoulders and a back.
- Shape long arms and clawed hands.
- Secure all wire ends toward the inside.
- Add a simple head shape.
- Hide small lights behind the eye openings.
Estimated cost: $15–$30.
Safety: Wear gloves and fold sharp chicken-wire ends inward.
5. Build a Glowing Witch’s Cauldron Around a Tomato Cage
This project uses lighting to do most of the work. Green LEDs inside a tomato cage can make an ordinary black planter or plastic cauldron appear to glow and bubble after dark.
What You’ll Need
- Tomato cage
- Black cauldron, planter or bucket
- Green LED fairy lights
- Black fabric
- Optional potion bottles, moss or skulls
How to Make It
- Place the cauldron in front of or inside the cage.
- Run green lights vertically through the cage.
- Cover exposed wire with black fabric.
- Arrange bottles, pumpkins or skulls around the base.
- Turn on the lights at dusk.
Estimated cost: $10–$22.
6. Cover a Garden Trellis With Tattered Cheesecloth
A trellis gives you a large vertical decorating surface without needing to build anything from scratch.
What You’ll Need
- Existing garden trellis
- Cheesecloth
- Plastic spiders
- Garden twine or small clips
How to Make It
- Tear the cheesecloth into uneven sections.
- Stretch and snag the material across different parts of the trellis.
- Leave large gaps instead of covering everything evenly.
- Add a few spiders.
- Let some fabric trail toward the ground.
Estimated cost: $5–$12.
7. Turn Your Trellis Into a Wall of Skulls
Cheap lightweight skulls become far more dramatic when arranged vertically instead of scattered around the yard.
What You’ll Need
- Garden trellis
- Plastic skulls
- Zip ties or thin garden wire
- Black mesh or gauze
- Optional warm fairy lights
How to Make It
- Arrange skulls at different heights before fastening them.
- Secure each skull with wire or zip ties.
- Drape dark fabric between them.
- Run lights behind the trellis rather than directly in front.
Estimated cost: $8–$20.
8. Make a Graveyard Backdrop With Black Mesh and Lights
This idea works particularly well behind tombstones or along the edge of a garden bed because the trellis provides instant height.
What You’ll Need
- Trellis
- Black mesh
- Orange or purple LEDs
- Artificial cobwebs
- Optional tombstones or skeleton pieces
How to Make It
- Stretch black mesh loosely across the trellis.
- Run lights behind the mesh.
- Add webbing across selected areas.
- Place tombstones or smaller decorations in front.
- Use low lighting near the ground to add depth.
Estimated cost: $10–$25.

9. Wire a Scarecrow Onto an Existing Trellis
A trellis already functions like the backbone of a scarecrow, so this is an easy project if you have old clothing in the house.
What You’ll Need
- Trellis
- Wooden dowel or stick
- Old shirt and pants
- Garden wire
- Straw or dry grass
- Hat
How to Make It
- Wire a horizontal stick across the trellis for the arms.
- Add the shirt and secure it around the frame.
- Attach pants lower on the trellis.
- Stuff selected areas lightly with straw.
- Add a head and hat.
- Let some straw protrude from sleeves and pant legs.
Estimated cost: $5–$18.
10. Create a Ghostly Garden Entrance With a Trellis Arch
This is the strongest entrance idea in the collection. A simple arch becomes much more atmospheric when fabric, lights and a little movement from the wind are added.
What You’ll Need
- Flexible arch trellis or two upright trellises
- White cheesecloth, tulle or light fabric
- Warm or orange string lights
- Ground stakes
- Optional lanterns
How to Make It
- Position the arch over your garden path or entry.
- Anchor both sides securely.
- Drape white material unevenly across the top and sides.
- Run lights behind the material.
- Place lanterns at the base.
- Keep the center open enough for safe walking.
Estimated cost: $12–$28.
How to Make Cheap Halloween Decorations Look More Expensive
- Use fewer, larger focal points. A strong witch or ghost arch usually looks better than ten tiny decorations scattered randomly.
- Hide the mechanics. Cover obvious zip ties, battery boxes and plastic bases.
- Layer your lighting. Combine a softly glowing prop with a separate lantern or pathway light.
- Use real garden plants. Grasses, fading perennials, autumn foliage and shrubs make the scene feel naturally integrated into the yard.
- Repeat materials. Using the same gauze, lights or black fabric across several decorations helps everything look intentional.
How Much Would It Cost to Make All 10?
If you had to buy every decoration supply from scratch, the combined projects could easily total around $100 to $200. But that isn’t really the point of these ideas.
If you already own the tomato cages, trellises, old clothes and a few strings of lights, you could create several of these displays for well under $50 total. Start with two or three ideas and reuse materials between them.
Frequently Asked Questions
Can I leave tomato cage Halloween decorations outside?
Yes, but lightweight fabric decorations should be secured against wind. Battery packs and non-weatherproof lights should be protected from rain.
Can I reuse these decorations next Halloween?
Absolutely. Remove fabric and electrical components before storing the cage or trellis. Keep gauze, lights and props in a dry storage container.
Which decoration is easiest for beginners?
The mummy, haunted trellis wall and scarecrow are the easiest because they require very little shaping or construction.
Which idea makes the biggest impact?
The towering witch, crouching monster and ghost entrance arch make the strongest large-scale displays.
Can these work in a small front yard?
Yes. Choose one vertical project such as a mummy, witch or decorated trellis instead of trying to use every idea at once.
Final Thoughts
The best Halloween yard decorations don’t necessarily come from a store. Tomato cages, trellises and other garden structures already give you the framework—you just need fabric, wire, lights and a few inexpensive details to transform them.
And because you’re starting with garden equipment you already own, these projects are easy to take apart and reuse when the growing season returns.
