There is a thread in "Growing For Market " forum About supporting hundreds of plants:

Since this idea may also work for non-market growers, I am posting it here.
I have not tried this because I have a different growing condition with my own unique support system.
There are many systems to support lots of plants, each with its advantages and problems.
Here is an idea for you guys to try out.
Using netting or wire mesh stretched at an angle, the weight of the plants will naturaly lean on the mesh, so there will not be a need to tie branches back.
Depending on what you are growing, most of the fruits may hang below the mesh for easy picking.
This will give better sun exposure and may also be better for spraying.
Just an idea to solve a problem with a different angle.
