Where the yard is unencumbered by trees overhead - the frost takes hold. The neighbour a few doors up (who by the way will shortly hitch up the caravan and leave for the long weekend) has no trees over their front yard and so, frost.
It was a chilly minus 1º overnight in Richmond, Judy was glad to hear that for she will be spending her morning on the oval at school (quite close to Richmond) as it is primary school sports carnival morning - it is at least sunny.
We did not fare much better when I arrived home from the dropping the car off it was 1.5º on our deck - a morning to find some good excuses to stay inside for a while!
The good news? We heard an expert on the radio who had been asked about caterpillars decimating cliveas (we have the same problem) saying that the first frost will see then end of them for the season - let's hope so.
