Is there anything I can do to see if my ash tree is dead or just very slow in leafing after we had it cut back last fall?
Do the branches snap and break off or bend?
You can do a scratch test on the branches. The links below will help you.
Weather patterns can effect tree leaf out, so depending on the spring temperatures that you are having you may need to give the tree more time.

My azaleas are suffering with what appears to be lichen. Last year I tried cutting off the affected branches. This year there are more. The adjacent ash tree also has branches affected similarly but still sprouts leaves. Please advise me what to do. Photo attached.
These azaleas have been beautiful bloomers until the last season. I was hoping you could identify the green lichen-looking stuff, as the branch die-back seems to be following it. I read the articles and none of the photos matched what is happening with these. I will examine the branches closest to the roots to look for phytophthora. I am afraid I will lose all 3 if I don't apply the correct treatment.
I can't determine an exact cause of the poor growth on your Azalea. The most likely causes are pests and disease.
These articles will help you pinpoint the issues and how to treat.

We have an Ash tree. Summer just started where we live and the leaves are falling from all over the tree. No other substance is coming off the tree. Below is a pic of the leaf I pulled off the tree and one of the way leafs are falling. I appreciate any feed back. Also, how much water does a 30 year old Ash need daily? Thank you from MN.
A guess as to why your ash leaves are falling is ash anthracnose, a fungal disease that afflicts ash and other trees in cool, damp, spring weather. It results in leaf drop and the leaves will typically have brown or black blotches that appear on the leaflets that often become distorted, curling toward the blighted areas.
Fortunately, anthracnose does not cause serious harm to healthy, well established trees. The affected trees continue to leaf out. Leaves that develop later in spring usually are not affected, as weather conditions are less favorable for anthracnose development. There is no need to apply a fungicide to affected trees.

In June I planted a young sapling mountain ash - I planted/watered it according to the instructions but the leaves starting drying up and now there are none. What can I do to revive it??
I'm sorry, it is a goner. I'd return it to the place it was purchased for refund. Most bona fide nurseries guarantee their plants.
I have had the purple ash tree treated for emerald ash borer last year and leaves have been falling off all summer. Please tell me why. Thank you
Did you have your tree treated as a preventative or is it detected in your tree?
If your tree is suffering symptoms of stress or disease, I would have it inspected again.
You may want to check with your County Extension Office to check on the progress of EAB disease in your area.
“Autumn Purple” ash trees suffer from several problems. The emerald ash borer, an invading pest, kills infested ash trees within five years if not sooner. Other insect pests include lilac borers, carpenter worms, leaf miners, ash sawflies and ash leaf curl aphids. Nests constructed out of webbing appear in ash trees infested with webworms. These are especially visible in the fall. Plant diseases like fungal leaf spots, powdery mildew, rust, anthracnose, and cankers can cause serious problems for the “Autumn Purple” ash tree.

I have recently cut down a 10 year old Mountain Ash, leaving the trunk in the ground. Will the roots of this tree continue to grow and possibly put out suckers in my lawn?
Yes, it is likely that you'll see suckers for a year, maybe two. Mowing should be enough to control them although they are easy to break off at the root which would be better.
How big of a root can be cut from an ash tree without harming the tree?
I would not cut any roots within 5 feet of the tree. These are massive nutrient vessels, and its only means of foundation. Anything outside of this will be fine.
