I have decided to try some grape vines in my small back garden. I purchased two grape vine plants in mail order. With the houses and trees around my property being close I had to position the new grape arbor in the middle of my back garden to get the maximum sun, right beside my 4x 6 mini greenhouse.
Step 1: Tools & Materials List
cordless drill with screw bits and drill bits
2 paint brush
deck screws, various sizes
4 lag screws with 4 large washers Galvanized
Stainless #10 1 inch screws and #10 stainless washers for attaching wire
14 Gauge Galvanized wire
2 bags gravel
2 bags cement
5 -8' 2x4 PT lumber
7 pc 2x2 deck rails
1 12 foot pc 1x6 PT cut in half at home depot (so I could get it in the car)
Various pieces of Scrap wood for bench not PT
Deck stain (left over from when I stained my deck last year)
Green exterior latex paint
Leftover brown paint and grimmer primer from other projects
Bagged garden soil
2 grow tubes for baby grape plants
Left over black garden weed block fabric
scrap wood for stakes and braces
Step 2: Measure, Mark, Dig
I am using 2x4 posts because 4x4s are just too much for me to handle on my own and I figured this is a small structure, it sould be ok.
Step 3: Placing the Posts
Step 4: Cement
Step 5: Top Assembly
I used seven 2x2x36 deck rails evenly spaced for across the top to make the slats attaching with deck screws.
Note: all holes for bolts and screws were pre-drilled. Because the front to back measurement on left and right sides was off a bit when I attached the top rails I had a half inch overhang all across the front, but in the back by the time I got from right to left there was no overhang on the last one or two rails.
Removed all bracing material.
Step 6: Plant
Planted the grapevines and put grow tubs (made for new grape plants to train upright and get established) over them with a garden stake to attach the grow tube to. It is only light corrugated plastic and would blow away if not secured. I also planted some flowers to the outside of the box and covered the rest of the inside area of the boxes with black landscaping material to protect from cats or other animals digging.
Step 7: Stain and Wire
I attached galvanized wire up each side for the trellis to train the vines on. I Started 20" up from the bottom and about every 12" to the top, drilled holes in all four posts. Pull wire through starting at the back and securing end by twisting wire with needle noise pliers tip into tight circle and securing to wood with screw and washer. Thread wire back to front pulling tight as you can until you get to the last post and tie off as in the beginning with the screw and washer. I ended up with 5 rows of wire.
I used wire instead of wood because It will not block any light and is almost invisible from a distance.
Step 8: Bench
Primed with gripper primer
One coat brown base color
2 coats green exterior latex paint
I also painted the two pieces of wood that I attached to the arbor posts as the back rest for the bench.
The bench is not attached to the arbor so I can just lift it out of the way when cutting the grass. It is not PT exterior wood, so I don't expect it to last more than a few years. I might bring it indoors in the winter time.
