It's Been A Long Dry Summer
We don't have lovely rich loamy soil in most places here. What we do have is a lot of grey sand!
Unless you're watering the garden regularly most things just schrivel up and die after one 40c day let alone multiple ones!
There are a lot of very large dry patches in the public gardens which haven't been watered in a long time. Amongst a sea of grey sand I spotted this one blade of green and admired its tenacity!
