A little advice needed if anyone would be kind enough to help a gardening novice!
We have a small garden 8.5 x 8.9m. Very overlooked from the back.
I’m planning to plant some Laurel or similar to create privacy - but was unsure if this is the best option. I don’t want anything that’s going to go wild and take over or get in to the neighbours garden.
I’d also like to get a small tree for the corner of the plot, to give some shade - we’re south facing and without shade most of the day.
Any advice or thoughts would be gratefully received. I don’t want to do the wrong thing so have done nothing as a result 
TIA
