I grow early season stone fruit west of Stanthorpe. Our varieties flower in late July and our location can experience frost up to the end of September. This risk was rammed home on 21 August 2018 when a sharp temperature fall just before dawn caused an estimated $150,000 damage. Climate trend predictions suggest later and more severe frosts will become more frequent and this is a risk we were unwilling to take any further. In July 2019 we took delivery of 2x new Tow n Blows. Already we have seen a 2degC lift in temperature on a comparable morning, relative to the -4degC frost event in 2018. In my opinion the Tow n Blow if the most cost effective frost mitigation on the market. The sales, and after sales service delivered by DTE Equipment was very satisfactory and I would recommend them highly.
