1) Can misapplication of mulch kill bushes? How? 2) How far from the center stems of the bush should mulch be applied? 3) Two of my convexus type hollies died last year. The roots were rotted. Other plants in the area also died. Heavy mulch had been applied in early spring over the whole area and covered the crowns of the hollies. Soil sample analysis didn’t reveal a possible cause. Could the mulch application have been the problem?

Should I keep treating my Ash Trees? #864873

Asked April 17, 2024, 2:04 PM EDT

We have treated our 2 ash trees twice, so over 4 years. We are due for another treatment but I see bark falling off in the upper canopy and we had a lot of sucker growth last year. There was dome thinning og the canopues as well. We are being told they can still be saved but that goes against what I learned in landscape horticulture school. Can you please advise on if they're worth treating.

Type of hydrangea and when to prune #864869

Asked April 17, 2024, 1:47 PM EDT

I recently moved to my home and don't know whether I have a hydrangea that blooms on old growth or new so I don't know if I should prune to the last green part (bud?) I'm seeing or if I should cut them a foot from the ground. I've attached a picture of what they looked like June 30th last year and what they look like today.

Ash tree #864861

Asked April 17, 2024, 12:35 PM EDT

My ash tree was diagnosed with emerald ash bore 3 years ago and I had it treated by an arborist. There was die back. I had it pruned. Now it has 2 areas of complete bark loss on 1 large limb and 1 small limb. There are buds popping out everywhere this spring. What should I do about the bark loss? What does it indicate? Please advise. Thank you!

erosion control on lake Champlain #864860

Asked April 17, 2024, 12:30 PM EDT

I live directly on the lake and would like to know what kinds of plantings I can use to help decrease erosion on our waterfront. Our next door neighbor has "vetch" planted on her waterfront. I don't know exactly what that is or how it is planted, or if it is the best solution. We would appreciate any advice we can get from the experts! Thanks.
