Fruit trees in raised beds- watering
I finally finished putting in my orchard 27 trees in all. I learned as i was going and due to a high water table in winter decided to put the rest (the last 13) in raised beds. Some, (especaily cherry bed), have a massive amount of soil in them and are 2ft + above the ground. They were well watered in intitially, soaked about a foot out all the way around but there is still alot of dry soil inside of the boxes that could be sucking the moisture away from the trees. I have re- watered a few of them once, when it felt dryer but I don't know what's going on down below where I can't feel. Even a moisture meter dosn't go down that far.
Should I just make sure the top layer stays moist?
Or soak the whole monster bed all the way 1 time?
We have not been getting our usual winter rains this yr.
