My arborist buddy that I worked with for years sent me this just now. These people exist, and they are proud 🤮

This guy started an outdoor services company in my area on October 19th and this was his first post on his company Facebook page. You better believe that I left a comment about him being proud that he did this job safely even though he clearly Barber chaired one of the trees.

Running some errands after work and stumbled upon this determined tree.

My Saucer Magnolia is blooming in the Midwest, USA, in autumn (October 24). Could it be because of unseasonably warm weather? Daytime highs are in the 70s; about 8-10 degrees above normal.

I am so concerned I suddenly noticed this browning in two of our Evergreens. Is this normal at all? The other ones are fine. Located in Geogia.

I am running my own version of the National Elm Trial in my yard. I planted 3 varieties of American Elm that I could get from online nurseries:

1. Princeton - planted 1 year ago (first pic)
2. Valley Forge - planted from bare root plant 6 months ago (second pic)
3. New Harmony - planted 1 month ago (third pic)

The Valley Forge was the most difficult to get going because I had to get it established in a pot before planting. However, this was the only way it was available. I’ll post an update in 7-10 years with the results!

Any tips would be greatly appreciated. I am in US zone 6b in Massachusetts. All 3 trees were planted with the root flair exposed, water regularly after planting, and mulched around the base.

I posted before about cutting this down or doing a crown reduction and thinning. I thought I would share how it looks now.

I think I am going to become a DIY arborists and over the next few years trim it directionally away from the house along with the reshaping the maple in front of it and 2 mulberry trees in the backyard. I want to remove the grass and dirt around the root mound too. Maybe put a little ring around it.

Thought I’d get y’all’s 2nd opinion on this. I have small tree in my front yard with a diverging branch shown in the photo where it splits off from the main trunk. It seems solid, healthy and won’t ever be an issue with property, so should I consider trimming it this fall?

I hired a guy to grind 4 stumps ranging from 2-3.5ft diameter. I poked around with an iron bar to see how deep he grounded them down, and the smaller ones were about 8”+, but the larger ones only seemed to be about 3” deep.

I’m disappointed because I told him we were going to add a concrete pad and landscaping, but not sure what the standard is with these larger stumps.

Went on a walk through Lincoln Woods state park and noticed all these trees had what looked like infected wounds or something? Anyone got any idea on the cause or if it will kill them anytime soon? So many of these had the same kind of malformations on them.

I put in hours of work on the acorn farm everyday, but alas the harvest never stops. I took 30 gallons to a SQUIRREL RESCUE this weekend and still have more. I fill up my 1 gallon acorn hopper at least 3 times a day while they continue to pelt my yard. I’m starting to go insane.

There is another one in the front yard that blows their load in December.

Has anyone gotten birth control for their slutty oak trees? Did it kill them? Was it worth it? How much to stop feeling like I’m in a hail storm in the backyard?

Edit: My house is the squirrel coliseum. Those tree rats are running up and down my roof all day, and eating my patio cushions by night. They cost me $250 just over a year ago with their bullshit.

We have only live here ~15 months and have zero experience with mature trees.

Edit 2: We have turf and I can’t just leave them on the ground.

Nursery just delivered this nuttall oak, should I ask for a replacement? It looks to have a fairly significant co-dominant branch.

As the Autumn continues, I am finding growths on my tree. I assume it’s a fungus. Can anyone help identify and know how to treat this?

I love this tree but im not sure what I can do to help, if anything. Bracing? Fairly new to tree health so I've got a lot to learn.

Any advice is appreciated!

And if so what should I use? Tree is about 20yrs old.

Bought a house because it's essentially surrounded by the woods and I love the smell of pine needles. I don't remember them looking this ratty when we were looking at this house back in May. I feel like I would notice this. Now after closing a lot of them look like this. Is this a problem? Or just something that happens normally? I would hate to have bought a house with 50 dead pines around it.

Contractor clipped through some roots pretty close to the tree. How much damage was done? The tree already doesnt look so great I dont think but I dont really know what Im looking at. Hoping a few knowledgeable people can chime in. Should I be concerned about this tree?

Im sure i already know the answer and they're not going to grow back but for some reason on the base of my pine tree I should say it's my Christmas tree that I have had growing in the yard for decades decided to die on the bottom in a portion of it. I'm going to guess it's probably from the Cherry Bush that was growing too close to it and maybe shaded out the light from the area?

​​ I was going to cut down the bush that was next to it but I think now that I have a feeling that that area will never grow back maybe I'll leave that bush there to kind of hide it?

Hi, I have a Kousa dogwood that I planted about 3-4 years ago. Last year I had some issues with deer scratching other trees on the property so I installed a metal mesh ring around it to prevent damage. It was loose enough but today I went to go check out the tree and noticed there were some leaves around it, not too many. But when I removed the mesh, I noticed a large area at the base of the tree that was peeling and looked different. Is this crown canker or maybe something else? What should I do? Thanks in advance !
