Making a tomato cage from wire costs under $20 per cage, using concrete remesh, livestock panels, or chicken wire formed into a 24-inch cylinder with 6-inch anchoring stakes.
The process takes about twenty minutes per cage using basic tools, and materials are available at any hardware store.
What Wire Mesh Works Best?
Strength comes from wire gauge. Light chicken wire needs internal stakes, while heavy mesh like concrete remesh or livestock panels creates a self-supporting structure.
- Chicken wire: Lighter and cheaper, but needs 5 straight sticks (12–18 inches) woven vertically at 12-inch intervals to keep shape. A 24-inch diameter circle needs about 80 inches of wire including overlap.
For best balance of cost, durability, and ease, concrete remesh or livestock panels are most practical.
How to Build in 6 Steps
Each cage starts with a 5-foot (60-inch) section curled into a 24-inch diameter cylinder.
- Unroll and measure. Hook the free end around a heavy object. Count 12 squares (roughly 5 feet) or measure 60 inches.
- Cut the mesh. Use bolt cutters to cut horizontal wires, leaving one side flush with a vertical wire. On the opposite side, leave horizontal pieces sticking out 6 inches — these become anchoring stakes.
- Form the cylinder. Roll into a cylinder, bending the long horizontal pieces around vertical wires on the flush side to hook them together; ensure it’s tight and roughly 24 inches across.
- Secure the overlap. Fasten ends with 2–3 inch pieces of galvanized wire, zip ties, or reusable garden wire. Place ties at top, bottom, and one or two evenly spaced in the middle — 3 to 4 ties total.
- Create ground stakes. Cut off the bottom horizontal ring to expose 6-inch vertical spikes.
- Install over the plant. Place cage over young tomato plant. Drive stakes into soil until base wire sits at ground level.
Safety note: Wear gloves and eye protection when cutting wire. Use pliers to bend sharp tips inward after trimming.
Common Mistakes That Cause Collapse
- Too-small diameter: A circle smaller than 24 inches restricts root spread and fruit production.
- Loose overlap: Use at least 3 ties evenly spaced along the seam.
- Weak anchoring: Stakes must be driven at least 1 foot into soil; less than 6 inches deep allows tipping. Drive deeper in loose soil.
For windy areas, drive T-posts at row ends and weave a PVC pipe or 2×2 board through top rings, wiring to posts to lock cages together.

Square Cage Alternative With Livestock Panels
Cut two 8-foot sections, bend each into a 90-degree angle (about 3 squares wide), and insert into soil to form a square cage. The square shape gives four flat sides for even growth, with 6-inch openings for easy harvesting.
FAQ
What is the best wire for tomato cages?
Concrete remesh or livestock panels offer the best stiffness, rust resistance, and cost per cage. Chicken wire is cheaper but needs extra internal stakes.
How many cages from one livestock panel roll?
Can I use a cage for bush tomatoes or only tall vines?
Works for both. Space plants 24 to 36 inches apart to prevent crowding.
