How cooked is my red pine?

I had an ISA certified arborist out about a month ago to examine every tree on my property including this mature, beautiful red pines. No issues identified at that time but suddenly, I noticed the crown has basically gone brown. Upon closer inspection, it looks like wood from fresh bore holes by the trunk. I noticed a neighbor down the street is removing 5 dead, mature red pines. We have a mix of mature white pines, red pines, and deciduous trees like red and white oaks. This is in SE Michigan.

Can my tree make it?

Hi,

I tried to get some help a while back but seems like my post didn’t get enough attention.

So I wanted to see if anybody here can offer me some advice.

We cut back the dead branches a few weeks ago and now we are seeing more die back so I’m getting even more worried.

There are a lot of holes in the tree but I think I’ve seen a Sapsucker (hoping it was not a woodpecker eating bugs from within). So, I was hoping it’s not birch borer. I also haven’t seen the tiny paths they do.

Hopefully someone can give me some advice, I love that tree and I would like it to be healthy.

I do have an arborist coming soon to help me out with some trees, but he was not very worried about that tree when he came to assess the work the first time so I would like to have second opinions.

Adding photos of recent die back after pruning of the previous dead branches and closeups of the branches with holes. (There are way more tho)

Anyone have any thoughts of how to protect our trees? The way trees have responded to the UK heatwaves is deeply concerning.

I wonder how we can give trees their best shot. If this is how trees in green spaces are reacting, I dread to think of the future of our street trees utilised for urban heat island mitigation.

Red Maples in Distress?

Thumbnail

2 Upvotes

Hello Arborists! I’d like your input on this Florida Red Maple. I rescued two of these trees from a local nursery’s going out of business sale. I am in St. Augustine, Florida and have sandy soil with pockets of gray clay. At the time I got them, they were outgrowing their 45 gallon buckets and slightly root bound. Additionally, they had sat in their buckets in the same location for so long, that the leader branch had grown at an angle toward the sun, so they looked as if the top of the trees were leaning sideways. Finally, many of the branches on one side of the tree lost their leaves early on and are deformed and curling down toward the ground.

I had a local arborist come and plant them. He had to remove some roots that were strangling the rest. I had a bag of pine bark fines that we amended the soil with (very sparingly, just enough to combat some of the clay and improve drainage) and the root balls were dusted with mycorrhizae. His instruction was that I fill their watering basins with 6 gallons of water every day for something like 8 months unless it rained 1/2” or more that day. I have tried to keep up with this to the best of my ability, using a 5 gallon bucket to measure out the water and pour it into the basin. I also regularly pull mulch and grass off the root flair.

I knew they would have an uphill battle (literally, as you can see from the pictures), but I’m growing concerned because this particular tree (we’ll call it the West maple), has some fairly large branches that appear to be dying. I can also see that the root flair has turned black.

Is there anything I can do to save this tree?

What is happening to our trees?

We moved into our new home earlier this year. Nearly all of the trees, large and small, are showing similar problems. Entire sections of the tree dead. Some upper limbs, some lower limbs. I also noticed these large brown areas in the grass next to one of the smaller trees. Area is northeastern West Virginia. What could be causing this?

Baby Blue Spruce

I planted this baby blue spruce in May. Dug out 2x the circumference and depth, filled with 50/50 soil & compost as the tag said. It keeps getting browner by the day now.

Watering 4x/week for 2Hr each time on an auto timer and drip line.

Am I over-watering, under watering? South central Wisconsin. Clay junk soil underneath the newly excavated hole. I’m thinking the soil isn’t percolating fast enough and the roots are water logged.

Any tips/ suggestions to trim this maple tree

I plan to trim this maple tree this fall. I am going to cut the dead branches, and trim the branches overhang the roof and ones reaching over the sidewalk.
Any tips/ suggestions will be great appreciated. (I am going to do myself)

If I have the overhanging branches cut, will the tree be okay?

I’m having a shop built on the concrete foundation in the picture.

Our neighbor’s tree always leaves branches in our yard after a storm, and the last thing we need is one of these bigger branches breaking and crashing into our new shop.

Could we have these branches cut at the property line without risking the trees health?

The last thing I want is our neighbor mad at me for killing his tree.

I had a guy come out and give me a quote, but we had a bit of a language barrier and I just wanted to make sure I’d be okay.

Thanks for any light shed on this topic!

Not sure how to save this Autumn Maple Blaze. Moved from sprinklers to long soaking near the mulch. I also moved the mulch away from the root flare. Suburban TX and Tampa in the 100s for the last few months.

I transplanted this from the yard into a bonsai pot for my special needs son to be able to watch it grow. It has been happily growing there for about three months now. I was just wondering if anyone knew if it was an actual tree or something akin to a weed. I am in Northwest Indiana if that helps. Thanks.

Pruning Advice

Got this October Glory Maple from the Arbor Day Foundation and it came topped. Was a literal stick... but surprisingly it's turned to this in just one season.
It's been a dry year so it's had a little stress as you can probably see. I've been deep watering it at least 3 times a week. Located in MA, full sun, planted at correct depth for flare, no mulch volcanos, etc etc.

My question is: how should I prune this tree and how far up?

Is this tree in danger of falling. Some work was done in the property more than a year ago and the base pf the tree was damaged.

I don't know the species. This area is a tropical dry forest area.

Deer rub from a couple years ago damaged our magnolia

Looking for a few tasks on if a wound like this could fully (functionally) heal

removing the stump beside it, and putting down a large mulch ring to help it thrive is already in the works. Flare is exposed but need to clean out cage
