DIY a frost protection wind machine

I have heard of serious damage on the continent to vineyards this year. My orchards are not having a great time of things but too early to say what size crop there might be yet.
If I was using frost protection it would have been every night for more than 2 weeks, that would literally be exhausting.
It certainly would be exhausting. It’s that balance between crop damage, cost and time.
I heard frost has been a real problem in France this spring. Only time will tell what damage.

Local vineyard I speak to said frost reduced their yield by over half 2 years go. Only small but the income reduction was huge.

There are static machines out there that start automatically but how many you would need depends on acreage.

Wow,

Sorry to hear that. Doesn’t make it worth picking at that rate. What are you growing?
That was apples. We had 3 very cold nights in late May, it took out the fruitlets not the blossom.
I was hoping for a better go of things this year but not looking very promising so far, frost throughout blossom and hail last Friday. Too early to say how much harm they suffered, might even get away with it.
First time we had severe frost damage in 30-40 years so can't complain too much.

Last year frost took my crop from 30 tons down to 3 tons!
Yep, I've had one those years too while back 1/2 bin of Cox (160kg) instead of 30+. I think it worked out at about 1-2 apples/tree. Wore more boot leather out than the crop was worth. It sold quickly though....

I've not seen much in the way of mobile frost beaters, but there is a chap down Newent way that's got a big fan (3m dia) mounted on a vertical shaft in a cowling that draws the cold air in at the base and blasts it straight up. I think it's used in conjunction with a couple of small fires higher up the orchard to provide a temperature gradient.

Most apple blossom is ok to -4 until it starts to open, then anything below -2 will finish it off quite quickly. You tend to get the coldest temperatures just before dawn, 5-6am at this time of the year, then the sun rises and it warms up. However, despite the Met office and their millions spent on forecasting, you can never be too confident, or that you’re orchard doesn’t sit in a cold spot. I think you’d need to be having some sort of air disruption (fire?) going before midnight, then an early morning to strike up the fans.
 
Could you use compost ?

I don't know how much heat is required but a compost heap holds significant amounts of heat - you could either tip it in piles or pipe the heat into the orchard on demand.

You'd need a local recycling centre nearby (10 miles) or could even have recycling as part of the business model.
