    The tops of 4 or 5 of these trees are struggling. I am assuming since they are mounded up so high they aren't rooting well.

    What is that doing to the tree?

    Not to be lazy but if you Google volcano mulching it will save me a lot of typing.

    Agree Volcano mulching leading to decay of the stem tissue resulting in diminished water uptake to the top of the tree.

    Correct me if I'm wrong with volcano mulching but there is only a couple inches of mulch here.

    Look closely at that "Mound"! That is way more than "only a couple of inches"!

    volcano mulching = trunk rot!!!!!!! :mad::realmad: :wall

    Sounds like the tree was planted to shallow and dirt is mounded around the root ball with a couple inches of mulch. most likely not retaining enough water.

    Could be a number of issues. Planted too high. Burlap and rope left in place at the time of planting. Trunk damage during planting. Borers. The list goes on. Take a couple close up pictures of the trunk from different angles and pull away the soil and mulch from the base of the tree to expose the top of the roots where they connect to the trunk. Take a picture and post it. Also pull back an area of the mulch about 1-2 ft away from the trunk and verify that the burlap has been removed if they are B&B trees. Examine the dead limbs in the upper canopy closely to see if the bark is damaged. I've had a couple tree diagnosis this year with the same issue just to find it was squirrels chewing the bark off the trees. Good luck.

    In addition to others comments...

    Are we looking at Acer? I do not see any Taper where the trunk meets the soil line, and as stated before looks like volcano mulching. Is there trunk taper at the "Soil Line" when you pull back the mulch or are the trees still planted too deep?

    Do you know when the trees were planted? For each 1" D.B.H. caliper at planting time, the tree will need 1 year to establish rooting to resist drought stress. Example a 3" cal. plant at planting time will need correct watering for 3 seasons....Client education a must here.

    Dieback of the leader can follow a spring that favored Anthracnose with excessive leaf drop, or if the soil is too wet for too long a time......Poor Co2/O2 Exchange in roots, just to name a few causes.

    I would suggest you consult with a "Certified Arborist" from your area and spend the couple hundred bucks, and learn from a pro in person.

    Money well spent, You will be a more valuable professional, and your client will have peace of mind.

    Good luck.
