Q.Newly Planted Trees
We recently had a magnolia and 2 newport plum trees planted. All trees are young but have some establishment as they are full of leaves. How often should we water them and how much water should they need? We purchased a soil meter to monitor the moisture. Right now we water 2 or 3 times a wk and the soil usually reads between 6 and 10. We have noticed tree stress since the nursery planted them. What can we do to save our trees??

Why are there holes in the young Newport plum? I hope you don't already have tree borers. I would contact the nursery about the holes. Newport needs moist, well-draining soil. They may be getting too much water if the moisture meter gets over 7.
Magnolias also prefer moist soil, but not saturated. I would cut back the watering a bit and see if that helps.
