Q.Best method to deep water a macadamia tree

Zone Lakewood ca. 90713 | RonzNutz added on June 11, 2019 | Answered

I have a mature 45′ mac tree in so. cal. In summer of 2018, after years of drought and a few days of 105 plus temps, it dropped a large % of its nuts in an act of self preservation. I would like to try deep watering this summer and question whether to water at the drip line or closer in to the trunk or both? Tree appears to be healthy as ever right now.

There are no feeder roots near the trunk, and the large roots will not take up water. They are only for stability.

In order to deep water, you will have to move out from the tree several feet, and then water. Sometimes it can help to bore a few holes down into the ground to let water penetrate through tough soil if this is the case.
