With the California drought in full swing, I'm wondering whether I could cut back on irrigating my orchard by doing things slightly differently. We're on a well and it's started dropping precipitously. Currently I'm watering 60 minutes once a week. Would it be ok to water every other week, but water 90 minutes instead? That way I would save 25% of water, and it would be a deeper watering. But, of course, also only every other week. Thoughts?
Your trees will benefit more by the deeper but less frequent watering. Its the moisture below the surface that counts. But in between the watering I would spray the tree leaves, trunk ect. Not long but enough to get them good and wet. Some water is absorbed through the leaves. And it would keep the dust off.
