Attaching willow trellis to wall

I have purchased an expandable willow trellis recently and would like some advice on the best way to attach it securely to a wall. I have cut 3 pieces of wood baton, treated them and fixed 2 of them to the wall. I have stretched the trellis out (see pic) and I don't think I need the third central baton as the trellis seems quite sturdy. I'm just not sure what is best to use to attach it to the wooden batons! The trellis is about 7ft high in total.

 

Julie, I`d be inclined to use netting staples.

 

Yip
It doesn't seem to need another baton
Staples should do fine

 

I have used those kind of fixings for a metal mesh on a rabbit run before. I did not think you could get ones large enough for this purpose. This is ideal, just got to find some!

 

These do?

 

You can get them in various sizes Julie. See if Newquay garden centre have them.
