Fans, Vines and Frost Protection
Well the conditions seem ideal for another frost tonight. The winds have calmed to near zero. Temps are at 45.6 degrees and falling, dew point is low, skies are clear. Needless to say I am concerned and not quite sure what I am going to do.
One thing I did is I went out and dropped $200 on an industrial size tubular fan from Lowes, it’s a big sucker with wheels. I positioned that on the slope facing the lowest portion of the plants that have budded out. My hope is that the extra air movement will buy me a degree or two by mixing up the air a little and not allowing the colder air to settle.
We’ll see how well it works! I am monitoring my weather station data every ten minutes and plan to get up around 3am to see where it all stands…remember, the lowest temps are always just before sunrise!

I’ll post a couple pictures of the fan. In speaking with my farmer friends, they thought you could pick up dairy or chicken coop fans for $50 or less at auction. They are larger and have even more power.
I really don’t know enough about how fans work to know if using a fan helps. Well I know it helps on large vinyeards with large fans that are mounted up aways. But it would seem that for vineyards on an acre or less, that are in areas prone to frost, a high powered industrial fan might work.
Now that I know about the protective properties of copper, I will probably try that next time as well.
