We don't advise using Yates White Oil on citrus during late autumn/winter as the oil settling on the leaf during cold periods can also cause a burning effect on the leaf as it does during the hotter months of the year. If you would like to use a horticultural oil on your citrus at any time of the year, we would suggest you use the Yates product, PestOil as this product contains unique UV protectants.
