Winter orchard watering
Our typical rainfall is a bit too low for most fruit trees (apples, pears, plums and cherries), so I supplement with irrigation. I try to keep the trees well watered through the fall, until the ground freezes.
I also will water mid to late winter whenever there is a warm spell of 4 or more days and the surface is no longer frozen over. I have been doing just that for the last week or so, as we had a nice warming and the ground surface was thawed.
However, it occurred to me that perhaps this was a bad idea, as the ground remains frozen 6" or so down. The water all soaks into the ground within 10 mins or so after the watering stops, so there are no puddles of ice forming around the trees. But still I am concerned if water at this time might do more harm than good.
What do folks think?
