I would have liked to see the girl do her show garden as well.
I suppose the point is that they only had the space and materials to create two.
As an eater, I would have liked to see a few food producers in the gardens. Can't eat a fatsia. Firethorns too are a pain much better a red currant. A nice small apple tree in the corner at the back would have been nice. A few strawberry plants. A couple of courgettes. Whoops I think I have already filled the space.
