I only have a smallish newbuild garden (11x5m) and want a nice fruit tree that doesn't take over the space but screens us a bit from the people at the bottom of the garden.
I thought maybe nectarine, but I'm unsure how much fruit they bear after 2-3 years and how long it takes to get to full height. I am also not sure where to buy a decent one that will actually take to the garden, without paying silly amounts of delivery. None of our local nurseries do them.
The garden is currently just grass.
