Are you still having heat wave?
We're over in Australia where it is winter, but it's like a typical English summer.
We've left our garden unattented with no requests to water or anything as I feel it will be a pointless exercise.
Our Bougainvillaea hedge (to be) thrives in dry and warm/hot conditions and everything else will come back eventually, but I'm not holding out too much luck for the lawn, at least I won't have to mow it on our return.
How's your garden growing?
