Why is my pin oak tree dying? #865550

Asked April 23, 2024, 9:52 AM EDT

We have noticed that one of our two pin oak trees is losing its leaves on the inside; and all inside branches are now bare. Outside branches have some new leaves but far fewer than it used to have when it was healthy. We noticed this last year but it’s worse this year. I don’t see any visible insects on the branches or trunk, which is approx 10 feet around at the base. It’s about 40 feet tall. I do see some splitting and green “moss” and fungus and other stuff on some of the branches. Please see my photos. The tree is about 28 years old. It’s planted in rich soil that used to be agricultural (growing soybeans and maybe corn), then turned into a small subdivision in southern Anne Arundel County (Harwood, MD). We had an older maple tree die a few years ago (located about 200 feet away from this tree). Someone told me they thought it was possibly anthracnose. Do you have any idea what is happening and how we can save this tree? I have many more photos I can send. Thanks so much in advance.

what is this insect? #865509

Asked April 22, 2024, 7:53 PM EDT

Hello, this past week I've seen about 7 of these insects in my study. I never have food or drink in this room, and haven't seen them in any other room. The one in the photo is not quite half and inch long, some of the others are smaller. I live in SW Portland, if that helps. Thanks for any info you can give me, Nanette Klimkow

Dying wax myrtle #865504

Asked April 22, 2024, 7:31 PM EDT

Thank you for your help! I’ve recently noticed that my wax myrtle is not very green & leaves are dead on the tree- it’s been with us a long time, so looks like a tree. A quick glance online mentioned a potential problem could be a foliar fungus. I plucked a green leaf off & noticed red speckles all over it top & bottom. Any advice would help me in my next steps.

Tiger Moth #865460

Asked April 22, 2024, 2:59 PM EDT

Hi There,

We have property in Cripple Creek, CO. and found a dense silky white web in the top of our Douglas Fir.   The tip of the tree is totally brown, and with binoculars I have spotted caterpillars on the outside of the web.  I can't identify the caterpillar markings from where I'm at.  I'm attaching a picture.  We are trying to determine if it is a Tiger Moth or another species and if so, what needs to be done so it does not spread to the surrounding forest we own.  If this is not the office to direct this question to and you know of the correct location, can you please let me know?  Thank you so much! 


Warmest,

Amy Lucitt

We would appreciate any help. Thank you

Comment for Emily Porter #865372

Asked April 22, 2024, 3:25 AM EDT

Hi Emily. I just read your article about cherry laurel problems. The first thing all of you need to tell homeowners the names of native plants that would be good replacements. You could explain that native plants are adapted to the region where they are grown so they are naturally more resistant to diseases. Many are deer resistant. Thanks for considering this request.

Bark Borers? #865362

Asked April 21, 2024, 10:00 PM EDT

I had to remove two evergreen trees from my property this week that were completely dead. I could hear loud wood chewing sounds coming from the trunks, so I peeled back some of the bark and saw what I believe to be some kind of bark beetle or borer. I can hear similar chewing sounds, less active, coming from a mostly live tree near where the others died. Is there anything to be done to save trees from these bugs? Or once they are in the bole is there no choice but to count them as good as dead, cut them down, and burn as quick as possible like the others? Photos attached.

Sweetgum Tree in Crisis? #865359

Asked April 21, 2024, 9:16 PM EDT

Attached are photos of a 30 year old sweetgum tree that grew on its own in our yard before we realized what it was and the nuisance the gum balls are that drop every fall/winter. Nevertheless, it is a nicely shaped tree and provides summer shade. Last year we noticed some branches high on the crown were de-leafed. We attributed it to leaf-eating caterpillars. This year, as the tree leafs-out, we are noticing several branches near the top appear dead. Can you tell if the tree is dying, experiencing stress from climate change or is this a natural occurrence for this type of tree? It gets plenty of water and sunlight.

What are the most deer resistant shrubs to plant for a privacy hedge? #865357

Asked April 21, 2024, 8:53 PM EDT

Hello, I was wondering if the extension office has ever answered a similar question or has a list of the best evergreen trees or shrubs to plant for a privacy hedge. When researching online, there’s a lot of conflicting information about what trees and shrubs are actually deer resistant. Many websites will claim that eastern red cedars are deer resistant, while on other websites, people will claim that it’s actually western red cedars that are the most deer resistant. I’ve seen arborvitae’s of both varieties sustain deer damage. Do you know if any junipers varieties are more deer resistant? Thank you for any tips or information! -Ashley

What are these red sacs on trees in my yard? #865308

Asked April 21, 2024, 1:53 PM EDT

Hello! While trimming trees in our yard in Hilliard, we noticed these red sacs on our crabapple and sand cherry trees. They seem to be dripping a clear fluid. There are hundreds, if not thousands, on the two trees. We thought they may be some kind of insect egg, but couldn’t find anything online about them. Should we do anything about them?

Fungal or Environmental issue with ground juniper? #865289

Asked April 21, 2024, 9:17 AM EDT

We have had these ground cover junipers for about three years. The soil is a good amount of clay but has been amended for drainage while planting. They do well over winter but each year they get some orange tips while transitioning to spring/summer sun. This year they also some dry/dead looking areas at the very ends. They are easily snapped. All 6 of them have the same thing, most notably on the longest (newest) branches. We applied a fungal treatment for shrubs in case. Should we be worried, or wait it out?
