I will probably lay down a LOT of cardboard this year, with mulch on top. I can do this after 24 years of removing horse stall bedding, available.
You friend would need a Lot of compost to do that.
I agree with his chain link fencing.
When I bought my tomato fencing--really livestock fencing--2 years ago, I bought a 50 ft roll, 6 ft high, that had smaller openings than the cattle fencing that I had bought that DH and I used to use for 9 years to repair the 40+yo cattle fencing.

IMHO, the smaller the openings, the Better the fencing is for vining vegetables. Also, the better to tie up and wind tomatoes through, which I did last year.
I still have the five 4' tall, 12 ft long fencelines that I built four years ago for tomatoes, and I used chicken wire. It isn't tall enough for indeterminates, but has worked very well for two Fall crops of cucumbers and beans .
What Good is your fencing if you have to tie up ALL of the seedlings to help them climb?
NONE of the bean or cucumber seedlings asked me for help. I would go out and discover them clinging to the fencing. The ones that didn't were my fault bc I planted too far away from the fencing.
I planted 5 rows of sugar snap peas in the last week. Since they are 2yo seeds it was worth putting them into the ground to see what happens, and I have newer seed.
Two rows are on the tomato fencing and three are on the chicken wire fencing.
I plan to move all four 12' rows of tomato fencing right next to 4/5 of the chicken wire fencing. this is for my crop rotation. One of the rows has some shade, so it will be used for different things later in the season.
My planting will be interesting, some of the north side of each of the four rows, plants that vine better on chicken wire.
I have, in the past 2 years, planted beans and cucumbers directly UNDER the chicken wire fencing.
I even planted some of the north side of the fencing, just to see what would happen.
They all tried to migrate south for more sun.

Speaking of chain link fencing, I also plan to plant some vining vegetables on the south side of my chicken run, which is 12 x 30 ft of dog chain link fencing.
I really don't care if the vegetables are eaten by the chickens, or if I am able to harvest. Perhaps nasturtiums?
I have also read that sunflowers can be planted to shade cool weather vegetables as the temperatures heat up.
Certainly companions are helpful.
