The grass here in Abingdon is turning pale. The circle pictured above is at Penlon Place, with Our Lady and St Edmund church behind. Part of grass’s natural life cycle involves becoming dormant when the roots can no longer get moisture or nutrients . The grass will turn green again when there is rain but there is no telling when that will be.
There is also a lot of yellow dust on the pavements around the civic car park, and council offices in Abingdon. The trees above have fronds of paired leaves – probably some sort of ash, and blossoms that fall as yellow dust.
