I've only had two occasions where I've needed to be plowed, and they were 3 days apart. We've had about an 80 degree temperature spread between the highest and lowest temps here this winter (and that number will be close to 90 in a few hours). Crazy stuff
The only thing I'm worried about is how it will affect the plants. I know that we've had a lot less chill hours than usual this winter, but I'm not sure if it's been enough to affect fruit tree yields. I am also concerned about an early bud break followed by some hard frosts or a long cold snap. Guess we'll just have to keep our eyes on it...
