Are there any strains of fruit tree that would grow in a container? Ideally we would like a lemon tree on our terrace, or are we being too ambitious!
I'm no expert, although I would it expect it to depend on the length of time you wish to keep it in the container (e.g. a couple of years or indefinitely). Fruit trees that grow well in containers are dwarf lemons, dwarf nectarines and peaches and some dwarf apples. However you have to make sure that tend to them correctly as they will need more attention that trees planted in the ground. Try asking someone at your local garden centre, they'll know better what types will suit containers and the conditions on your terrace.
