We haven’t been allowed to pressure wash our patio stones since May 2022 as we have an official drought and a hosepipe ban here in Cornwall. I know – don’t laugh! We’ve had rain every day in July and August is not being much better weather-wise. Today we have paid a lovely man to do the job for us (using the water in our pipes!) and it looks wonderful. It has always been one of my favourite jobs, playing with water and then re-discovering the beautiful dendrites under the murk but in fact, it’s very hard work and today it has been done for us. So, here are all the different designs gifted to us by nature.
“Though they may look like fossil plants, dendrites are incredible and inorganic formations that occur solely due to interactions between physics and geochemistry. These branching patterns are made of manganese oxides and commonly form on the surface of sandstones.”
