I want to ask NDN if this is okay, but not sure if it's cheeky, so thought I would check here first.
The set up is this - two houses, we own both and NDN rent off us. We used to rent out our house too, but moved in here ourselves recently. At one point, NDN had a nightmare neighbour in our house, and asked if they could erect a low fence in the front garden, which they did. I think we supplied the wood and FIL helped fit it, but I can't remember. The fence is a picket all the way down, but with a few panels of trellis at the top before the picket starts. They don't have anything growing on it though.
We are in the process of renovating our front garden, and I'd really like a climbing rose or similar in the spot where the trellis is. Would it be really cheeky to ask to grow something on their trellis, or should we be putting our own trellis up in front of it?
