Wire Hanger Sweet Pea Climbing Trellis

Materials
4 white wire coat hangers
2 wooden stakes (36 inches long)
1 roll of garden twine
1 pair of metal pliers
Directions
1. Use the metal pliers to untwist and straighten each of the four wire coat hangers completely.
2. Bend each wire into a U-shape, ensuring the arc is nice and smooth to create the main climbing structure.
3. Insert the two wooden stakes vertically into the ground, spaced about 18 inches apart, ensuring they are stable and evenly aligned.
4. Attach each U-shaped wire to the stakes by twisting the ends securely around the stakes, creating a series of arches.
5. Use garden twine to tie cross supports across the wire arches, adding stability and additional climbing surfaces.
6. Check the structure’s stability, ensuring all connections are tight and the trellis is securely positioned to support climbing plants.

Variations & Tips
To adapt this trellis for different climates or plants, consider using galvanized wire for increased durability in wet environments. For heavier climbers, such as tomatoes, you might swap wooden stakes for metal rebar for added strength. If the garden style is more modern, use black coated wire or sleek metal poles to match the aesthetic. Additionally, the trellis can be painted to match garden decor, or adorned with colorful strings to enhance its visual appeal in any setting.
