Hello
So excited about our new garden! Am going to really go for it this year.
I have a not so nice open rail fence, which marks our boundary well, but doesn't give us any privacy from our nosey neighbour, and doesn't allow us to let our big (but lovely) dog loose.
I had originally looked at stretching chicken wire along it with a view to eventually training roses and honeysuckle up it, but it is very exposed (up the top of a big hill, on its own), and it was suggested to me that I might want to plant some shrubs to give us a bit of a windbreak to allow them to establish.
However, I've been staying with my dad for a while, and he has a really lovely hawthorn hedge. I love the blossoms, the berries, and love the way the birds are so drawn to them. I'm ashamed to admit I had no idea that it was one of the most common hedges, and they are basically everywhere. 
My garden is only 4m wide. If I put chicken wire along my fence to keep the dog in for now, could I grow a hawthorn hedge of my own? Or would it take up too much space in the garden? I can't see the dog trying to jump through something so prickly, so when it's established the fence can go. How long could I expect it to take for it to grow to 1.8m tall or thereabouts? And do you think once it did, it would give us privacy from our rather miserable old neighbour?
I'm sorry about all the questions. I'm a complete beginner.
