October brings cold south winds that blow through you, whisk off your hat, drop the dodgy branches from gums and lowers the overnight temperature to near zero. Last year, frosts wiped out walnut crops in the foothills at this time of year. By the river, on our flat orchard the temp is expected to hover around 3 C. The flowers have not yet formed so we should be OK.
But the wind, gusting at over 50 km/hr prevents me from spraying copper. I am stretching the intervals between applications this year to reduce costs, so am not concerned if I don’t get on for a few days. Its all risky. You could lose the crop to frost or blight.
Meanwhile, the wind is blowing our pollen into the next jurisdiction. Pointless really, as the next substantial stand of walnuts is over 200 kms to the north.
