A lot of urban dwellers don't have a cat, let alone somewhere to swing it (the 'cat' being a cat-o-nine-tails, not the purring kind).
We have two 'gardens', one with each house. Both are tiny, but both are essential to city life; not unlike a garage; of which we only have one!
Without them we would have nowhere to take our afternoon Tea and Battenberg when it's warm enough, nor would we have anywhere to hang-out the washing.
The one above is really TINY, it has just enough room for a few plants, a couple of tacky chairs, and a bird's nesting box. We have to keep pots, etc, to a minimum, otherwise the area would become completely unusable.
The 'garden' at the other house had become rather jungle-like and overgrown; very nice in its own way, but the plants/trees were occupying too much space so I've just cut it all back and it's now usable again. When the children were small, we used it a lot. We ate out there often, and I've even held BBQ's there in the rain. There is a huge Yucca plant (tree) that has ventured onto next-door's terrace, so that will need to be severely pruned.
I like this little space, it has a lovely atmosphere. It always feels comfortable. A green oasis in the centre of the city.
It's a good thing that I enjoy gardening; even on a postage stamp scale. It's just a shame that there's nowhere to plant a few Tomatoes, or some Spuds.
