Having recently moved into a house with a blank canvas garden, I’d like to add some hedges and trees in to add some privacy and some security.
Having a quick look online it’s really quite overwhelming!
I love spending time doing a bit of gardening, but I would most certainly class myself as a novice!
Any suggestions of where best to buy trees and hedges. Garden centre? Online? And what kinds? Pots? Root balls (whatever that means!)?
It’s become quite clear that to buy plants to create a hedge and a couple of trees will be a bit pricey and I don’t want to risk killing them off!
I’m very excited to create a little haven, but as I’ve said, a little overwhelmed! 
All advice greatfully received.
