How to trellis vines to shade the window

I had an idea and would need some thoughts from fellow Permies once again!

The plan was to grow tomatoes in pots in front of our house and make a  wooden trellis grid on the walls. It does get hot in there but I hope not too hot for them to fruit...

Then I thought that I could shade the kitchen window with vining plants.. Snack cucumbers and cucamelons came to mind! However I'm not sure how to trellis them..

Here's an awesome drawing I made:



I don't think I want to do a wooden trellis grid over the window..

I thought I could hang some kind of strings or ropes from the roof "overhang". But would it be enough? Then I thought maybe sticking some kind of poles to the ground but I don't think there's a possibility to stick them deep enough because of the styrofoam that's underground not too deep.. Any ideas?

Also if you have a vining plant that doesn't mind the heat in mind, do share!

What about using chicken wire fencing attached to the boards above the window?

String or wire might work the same way.

I am sure the tendrils will grab the string, wire, or fencing.

Cucumbers sound good though some pretty pea or bean plants might be nice, like scarlet runner beans because they are pretty.

I like a nice biodegradable string. End of season you just cut the string and the whole lot goes in the compost.

If you already have an overhang to securely attach it to, it would be ideal. Climbing beans work very well on string because they twist around it securely.

B eans! Yes! Green beans! I really like them. Beans and cucumbers also like eachother!

I have never grown any kind of beans, this will be exciting.

I do have some chicken wire fencing from the old run I took apart… I just don’t know if it will look horrible before the vines take over. It would also have to be rigged in someway so that I can take it down in the fall without leaving too many holes in the wall..
I’ll think about this one, thank you for the great idea!

Oh and peas, I really like them too..! I wonder if they can handle the heat though..

Michael, I didn’t notice your post earlier as you posted while I was writing my reply!

That would be very convenient, to be able to cut everything down as a one huge screen of green (hopefully, this all might fail marvelously!) and then compost.. If using somekind of string, how should I attach it from the down end.. I’m going to be growing in big pots. Maybe put the strings under the pots?

I ordered some cucamelon and green bean seeds! So for now it will be…

Snack cucumbers
Cucamelon
Green beans
Peas

The weight of the bean plants themselves will keep them hanging straight. For the first few weeks, while they get established, tucking it under the pots will be enough.
