The trellis plan is fairly simple:
A) Two 8' 4x4 treated lumber posts form the sides. They should be set in concrete to assure stability.
B) A 72" long 2x4 to connect the posts
C) Another 2x4 this time cut at 84" to allow for some overhang at the top.
D) Set about 6 inches of gravel in a 2' hole for drainage and add concrete to secure the posts.
E) The vertical lattice slats are made from ripped 2x4s cut to 1.75" wide. This will allow for one 2x4 to be cut into 2 slats. These should all be long enough to attach to the top board (C) and the bottom board (B). If the bottom board is set 6" above ground level these should be 66". Measure the distance between the top and bottom boards to get an exact measurement. Space the slats evenly (approximately 6" on center) by subtracting the width of the two end slats then dividing your distance by the number of slats you are installing, more slats will mean a shorter spacing.
F) The horizontal slats are ripped 2x4 like E. Secure them across evenly at the same interval as the slats in E.
- 2 - 8 foot 4x4
- 10 - 8 foot 2x4
- Concrete and gravel to fill approx. 1.5-2 cubic feet.
- 2" deck coated screws
Pre-drill all holes to prevent the wood from splitting.
Approximate cost: $75-100 without paint or stain.
