I think this method is called, “Using Whatever’s Available.” It seems to work. I think it’s kind of interesting and matches the hodge-podge style of the space although I don’t think it would score points for curbside appeal with The Better Homes and Gardens crowd. It’s the kind of look I will miss dearly once the whole neighborhood becomes gentrified and scrubbed clean.
On a practical level I suspect that having the plants pushed so closely together like that will cause air circulation problems and possible disease at some point down the line. We’ve had a lot of rain this season causing tomato plants to grow very lush and bushy. Every local gardener I know has started pulling out leaves and branches to improve air flow.
Oddly enough this is not the first time I have seen this plastic orange mesh employed as a tomato staking method.
Here’s the full garden in case you’re interested. They have more edibles growing in the side yard.
