One thing that Norma requested I build for her is a hardy kiwi trellis.
Hardy kiwi is the cold-hardy cousin of the vine that produces the familiar kiwi fruit sold at grocery stores. The latter is the species Actinidia deliciosa and is hardy only to USDA plant hardiness zone 8. Hardy kiwi is much more cold-tolerant and can be grown in zones 3, 4, or 5 (and up to 8 or 9), depending on the variety. Like its warm-weather cousin, hardy kiwi also produces a sweet edible fruit, but the hardy version is smaller (about the size of a large grape) and can be eaten whole, without peeling.

I've never tasted or even seen a hardy kiwi. But Norma was pretty excited about growing them so I figured I'd support her on this. This is just one more step in us becoming self sufficient.

Between May 18 and 29, 2020, I built the trellis.

We decided to place it just uphill from where I installed the Bamboo Shield, on the northwest section of our lot. Here, I staked out the location for five posts, each spaced about 10 feet apart.
Each female kiwi plant can produce 100 pounds of fruit. A trellis to support that kind of weight has to be pretty strong so for each of the five posts, I dug an eight inch diameter hole, three feet deep.
Then I inserted a 9.5-foot-long ground contact pressure treated 4x4 and used 200 pounds of concrete (dry weight) to set each securely.

Here, I've got the first and last post put in place. The cross piece at the top is a five-foot-long pressure treated 2x4 secured with two galvanized carriage bolts. Everything has been stained to match our fence and deck.
Now I've got them all set up and leveled. I'll wait a few days before continuing to make sure the concrete has hardened sufficiently.
I ran two galvanized poles through the top holes and then bolted them in place. Like people, the posts are stronger when they work as a team rather than if they stand as individuals. The rigidity of the poles ensures that the posts can't be pulled together, which would be the tendency as the fruit gets heavy.
Four nine-gauge galvanized wires will support the weight of the plants.

Twenty anchor vises inserted into the 2x4s ensure the wire can only be pulled in one direction (like a diode), ensuring the cables stay taut. This was the first time I ever used anchor vises. They are amazingly strong.

I also drilled holes through the ends of the galvanized poles and ran bolts through them that hold a chain where Norma can hang a bird feeder or whatever decorative item she wants.

Here is the final product. For more information about building a hardy kiwi trellis, see YouTube - Kiwi Trellis.

On July 31, 2020, high winds brought down a piece of my neighbor's big pine tree. A huge branch took down part of the kiwi trellis. Needless to say, I was not happy but I was very pleased that my neighbor, Dominic, helped me with the chainsaw work to ensure the branch did not cause more damage. At least our redbud tree and fence were left unscathed. A few days later, Tropical Storm Isaias came through but just brought a lot of rain.

That big pine tree to our north will never be the same.
The worst damage was here. This post is now crooked and so is the one behind it.
That's a lot of branch.
The redbud (the smaller tree on the right) was barely spared.
On August 6, 2020, Norma and I worked on fixing things. She did the remaining chainsaw work and cleared the debris. I purchased a couple of three-foot-long steel corner pieces and lots of hardware to reinforce the top part of one of the posts which had broken off. I also glued the broken pieces back together though those pieces really became more cosmetic than functional thanks to the steel corner pieces. I sawed off the bent pole and replaced it with one I had lying around, ready to use to mount a birdhouse. The total material cost for repair was $29.23.

Below is the final result. Only the eastmost post has any noticeable changes. The two eastmost posts are not perfectly perpendicular with the ground anymore but the deviation is not obvious. Also, the section of pole that I replaced is a different color.
Looking east at the eastmost post, you can see how much reinforcement went into fixing it.

As of 2023, the plants are producing a good bit of fruit, though it is still far from the 100-pound per plant yield that we hope for.
