willow acacia problems

20 years ago

My willow acacia, planted 2 years ago, has done so well and is a handsome tree, perfect for my backyard. In the last few weeks, some of its leaves are turning yellow to brown and finally dropping. I don't see a pattern- this is on new and old growth, top to bottom, but not all over. More than half of the leaves on the tree look green and healthy. What could be causing this? Is overwatering a possibility? I don't see bugs, but there might be something really small, I suppose. Any thoughts?

All trees, even evergreen ones will shed leaves.

How is it being watered?

Thanks-
This is more than what has been typical of this tree. It gets watered about once a week by slow soak for several hours. I wonder if this is too much for a 2 year old tree...

2 wears ago we planted 2 willow acacias in our yard. One is doing well and other one(20ft away) is very scraggly and does not have a lot of new growth. They are both on a drip twice a week for 2 and a half hrs. Is there anything I could do to encourage better growth. Its leaves are not browning or falling off, its just not full like the other one. Could part of the problem be that it lost a fairly large branch to a wind storm last summer?
