I am planting a number of elaeagnus umbellata but I am not sure how much water will it need in order to produce well/stay healthy. I know it can be a drought tolerant tree once established.
However I am planting them in the middle of other fruite trees like apples, pears, plums, peaches etc. and I wonder if it can benefit from the same (or similar) amount of watering as will be provided
to those fruit trees. I have lines of fruit trees and the elaeagnus are in the same lines as the fruit trees, say every two fruit tree there a N-fixer (the elaeagnus)
The climate of the area where the orchard is is semi-arid with 600 mm/m2 / year average (in good years) but it can easily go towards 400-350 mm/m in more droughty years.
Same question for the Ealeagnus multiflora only that they are in separate lines together with other drought tolaerant native bushes.
The soil type is silty-clay mostly, still poor in organic matter.
Any help appreciated
