How to Build a Garden Trellis for Grapes and Kiwis

For years I’ve had great plans to build a garden trellis for my many varieties of grapes & kiwis – and finally this summer I took the plunge. I built a simple, but solid trellis for the vines I have growing along the south side of my garage. It’s probably a little bit over-kill, but it’s certainly able to hold the weight of all my grapes and kiwis (which is actually pretty significant – as I have two grape vines and two kiwis and all those vines, leaves, and fruit can get heavy!)

So if you’ve been looking to build a trellis in your own backyard, let me show you my design:

First of all – my materials list.

  • (3) 4 x 4 x 12′
  • (1) 4 x 4 x 8′ – (since my one section is under my garage window)
  • (17) 2 x 4 x 8′
  • (1) 2 x 4 x 12′

The first thing to do was to dig my post holes. I dug 6″ holes about 32″ deep – spaced 4′ apart – about 1′ from my garage wall.

The 12′ posts were too tall to fit beneath my garage eaves (even when planted 32″ deep), so I had to trim a few inches off the tops to fit just under my eaves. I had a window (as you can see in the picture below) that I didn’t want to cover up, so I planned to build that section at half height. Once the posts were in, I backfilled with gravel and tamped them in. You could use concrete if you like, but I think gravel holds it just as well (if it’s well tamped) and it allows the water to drain away from the post so it doesn’t rot.

Once the posts were all trimmed to the proper, level height, I simply attached the 12′ 2 x 4 to the top of the taller sections, and a 4′ section of 2 x 4 for the shorter one.

Grapes: They can actually grow in Alberta!

This week I experienced my first real grape harvest. Sure, I’d had managed to grow a few small clusters before – just enough to get a taste. But this year was the first year that I’ve been able to grow enough grapes to eat all I wanted fresh, plus harvest enough to make up some delicious grape jelly for the winter.

I have four different varieties growing in my yard here in central Alberta, but the two varieties that are mature enough to produce are my Valiant Grapes, and my Marechael Foch Grapes. The valiant grapes are larger than the marechael grapes (though still smaller than what you might find in the grocery store) and are packed with flavour! In fact, they are very similar in flavour to the Concord grapes that you buy in the store.

I have them growing on the south side of my garage on a trellis with my Kiwis. (Yes, you heard right… with MY KIWIS.) I’ve found this location to work great for three reasons!
