We're going to have a freeze here tonight. My pear trees have already pollinated (just barely dropped the flower petals), and I want to save the fruit.
Is fruit susceptible to freeze loss once already pollinated? I have some small propane heaters to run under the trees to generate a little warmth.
The heaters may work but a better way is set up a sprinkler.
I agree with Peternap. FIf you don't have a sprinkler then take a garden sprayer or if you can get a hose to them just wet everything down really good.Unless it is a really hard frost you should be ok.
