Alan & Judith,

Can we safely assume that these are not the trees with the oil problem from
last year?

If not, then it does sound like sunburn, and it does seem to be one of those
random things ... I have little bits of sunburn on some trees but not all
trees are affected.

I haven't bothered to do anything with mine as it seems too minor to worry
about, but I seem to remember somebody saying that you should paint the
trunks with white emulsion paint to reflect the sunshine and protect the
trees ... or is this an old wives tale?

Mike Wilson.
