Tools needed
- ·Circular or miter saw
- ·Cordless drill / driver
- ·Shovel or post-hole digger
- ·Tape measure and level
- ·Socket wrench set
Common mistakes to avoid
- ·Notching the top beam too deep — weakens the arch
- ·Skipping concrete footings — it rocks in the wind
- ·Wood touching soil directly — rots the posts in 2–3 years
- ·Spacing the slats too far apart — small vines cannot climb
Maintenance tips
Seal or stain every 2–3 years. Tighten bolts each spring. Prune vines before they overtake the structure.
