I'm going for the first time this weekend, can't wait! I'll be with DP and future-MIL - she's a volunteer with the National Trust and very pro, but I'm hoping there might be a few ideas she hasn't seen or tried before.
For me, we have a large boggy clay garden - with the brambles and nettles finally under control, I've realised we're lacking some height. So one or two interesting tall things would be grand.
I'm really looking forward to just wandering around too - any must-see recommendations, timing/route planning, or tips and tricks from MN gardeners who have been before?
