Hi,
Welcome, we moved up from Burnley 2 years ago, originally from Preston but grew up in Kent, I know Bolton a little bit.
The nettles are a problem, we had 3/4 of our acre with them, but persevere with them and you will succeed. Roundup is great for nettles, not organic as we wanted, but the results are good. My garden is looking really good without them this year.
Enjoy building your small holding, it will become a great pleasure.
Elaine
