Can you do bird netting with pipes or they not strong enough?
Any kind of berries are insane I think. We grew some blackberries down the side of the house and past a certain stage it's now a mission to keep the damn thing contained, it's trying to take over! XD
mmmmmm blackberry jelly! My nana used to make the best stuff, and from wild blackberry bushes near her house.
I can well imagine just how much they'd grow around your house. I've bought a few thornless canes because those blighters are vicious otherwise.
fun fact: raspberries and blackberries don't like each other!
I should investigate how much some pvc piping costs, tbh. I've seen structures made from it (thanks Pinterest) so I know its possible. But I do prefer working with wood so we'll see.
