Idea's for a garden?

I'd do a few things. I'd fertilize the lawn and keep it watered to make it a lusher green. Then I'd create beds in the two back corners of the gardern and plant a small flowering tree in each with some annual colourful flowers in groups about a foot from each other. Just back of the annuals, I'd plant perennials in pretty colours. They won't take off the first year so the annuals in front of them will provide the colour. But next year, the perennials will flower more and you won't need the annuals.

If you make one of the beds bigger, you could put a pretty bench there or a birdbath. Just those things would make it look fabulous in about 3 months and much nicer in the meantime.
