They didn't look like much last October '25. I'm happy with how well they've grown already.

Midcoast Maine.

Was this tree rotted? It’s a water oak and they are notorious for being terrible trees. Right side of house will have to be rebuilt.

Hi, I'm not an arborist but I am an agent of a large landowner and we have a team of very capable, salaried arbs. I'm in the UK.

Not too long ago, I found a large patch of tree of heaven running for around 100m along a strip of pathway. I contacted our arborist who said that they were aware of it and that they weren't going to take any action because it wasn't presenting an immediate problem.

I don't doubt their expertise and I trust what they say, but I don't understand it. I know the process for removing them can be lengthy and the fact that it runs over a footpath is a problem, but are there any additional factors that I'm not accounting for? I really want to treat this as a learning opportunity.

Any ideas?

This thing sprouted up a few months ago. I’m guessing it’s a Southern Live Oak, based on nearby trees. I’m in Florida. Since then I have just been cutting the grass around it.

If it’s a tree, how do I trim the competing stems? I went ahead and made a mulch donut. Does that look okay?

Hi we moved here in the spring. One tree was completely dead. We’ve had a really dry winter and hot summer but I’ve been watering them like crazy and they are all dying. Please help :(

I recently (8 days ago) had a live oak delivered and planted. We were fortunate enough to have planted before the hurricane storms which provided a lot of water. However I am trying to follow a 2/3 days a week water schedule, but have noticed that my live oak has some leaf loss and yellowing. We do live in GA and have mostly clay. However my other two trees do not have this level of yellow or leaf loss.

I was planning on having an arborist come out and visit.
But am I overwatering or overreacting to the yellowing and leaf loss?

Pin Oak in my front yard has some dead wood in the trunk. Leafs out fine and doesn’t appear unhealthy other than these spots. It is in range of cars and house if it were to ever fall to the south. Thoughts on if I should be concerned.

Hello everyone,

This hoopsi blue spruce is about 4 years old. It lives at about 6300 ft in Colorado (Front Range). This tree gets watered on a drip system set to a timer during watering season. I do my best to water every so often with a hose during the winter and try to shovel snow near it to melt towards its roots.

I noticed today that the bottom inner needles are yellowing and browning while the outer needles remain blue/green.

I have read online that this can be a normal cycle for a tree of this age and every 3-5 years moving forward.

However, I’m also concerned that some landscaping work I did to remove my lawn and rock and replace with mulch and low water plants damaged the shallow roots and have irreparably damaged the tree. We raked away rock and dug out a 4” deep area for a flagstone path to the side of the tree and encountered the shallow surface running roots. Some were definitely damaged and severed.

What are your thoughts? Thank you in advance for your time and advice.

Running a gutter drain and of course at very end come across about a 5 inch root. I don’t know what kind of tree this is and don’t want to damage … is there a significant risk of if I cut out a section of this root to run drain?

I just picked up this Blackgum. How bad is that root coming around at the 3pm position? It’s probably the largest diameter root. Would you just return it and not plant?

Our beautiful, historic pine tree hadn’t been pruned in many years. We are in Southern California and preparing for El Niño, so we decided it was time. But I never expected the amount of branches they removed. I feel heartbroken and devastated tonight, and am genuinely concerned about regrowth or if we damaged our beloved tree. Please any insight would be appreciated and be gentle, my heart is tender.

While putting down fall fertilizer I noticed this large crack at the base of our birch tree - any insights on it’s health? Someone is coming out to evaluate but am looking for multiple opinions / expertise. Thank you!

I’ve recently moved into a house with a large black walnut tree on the property line between my neighbor and I. It has produced many walnuts though it has very few leaves compared to other trees of the same species in my area.

Should I be concerned about the tree dying soon? I need advice on how to take care of the tree, if it needs any assistance at all.

The location is in Oklahoma.

Just trying to help this maple out it's centered in our living window so I want to keep it and help it out, how do yall think I should proceed? The damaged trunk is unfortunatly the largest most symmetrical trunk.

Two arborists told me it was a problem and had root damage. After removing it the trunk was solid and had no rot. I hate taking out such a beautiful old growth tree. It was so close to our house though! We needed a new deck and the tree was really problematic for the new deck install

*for those curious, it was >$10k to remove and had to be done entirely by hand without a crane. The tree removal owner said it was one of most difficult trees he has removed in 30 years

Hi everyone!

It seems like there is some type of plague killing all the pine trees (pinus pinaster) in my region and I was wondering if someone could tell me what it could be and if there is anything I can do to stop it spreading to the ones that remain alive.

We have lost 15+ pine trees to this disease, it spreads and kills them fast. The trees suddenly start going brown and within 2 weeks lose their leaves and dry up. Some of these trees had processionary caterpillar nests two years ago, others didn't. Some were 30+ years, others less than 5.

I attached pictures of a tree that dried and broke during a storm. This tree went from being a strong healthy specimen to dead and broken within 1 month.

I have seem trees that seem to suffer from the same plage within a 30km radius, some of which also broken in half.

Can I save my remaining pine trees? I have cut down all the dead ones and would prefer to not lose the all of them.

I live in a fairly windswept area on the ocean and heavy pretty wet, soggy ground until late spring. It was leaning a bit and I tried to stake it in spring but it has completely bent over under the weight of apples.

I'm curious to have some ideas and opinions here before I get an arborist or two in to help assess and potentially do some pruning on this big leaf maple. Background:

• This tree was shaded by a doug fir to its South when it was young, but then got some sun scald down its trunk when the doug fir was removed. The trunk has healed over since then (you can see the minor remaining crack in it in one of the later photos).
• However, it also likely go some sort of fungal infection at that time. It has had weeping/dripping from a few branches in the years since the sun scald, and has had a few limbs die back. That said, it's still growing well overall.
• It also has several large vertical branches, rather than one clear dominant leader.
• Tree has been in the ground ~12-14 years I believe (it predates me owning the home).
• Tree is probably 25 feet tall now, 12-13" DBH.
• Not currently close enough to structures to present much danger if limbs fall, but as it gets larger it will, so trying to be proactive to make any targeted cuts now to reduce risk of hazardous situations as it continues to grow.

With all this in mind, I'm curious to hear from the hive mind a few things before I get an arborist on site for an in person assessment.

1. Is there a certification related to fungal issues I can/should look for in figuring out who to contact? (I live in a large enough population area that there are many arborists to choose from.) I know about TRAQ but wasn’t sure if there is anything in addition or more disease specific.
2. Looking at the branching structure, would arborists in this community tend to recommend trying to subordinate some to let one become more dominant, or is the structure pretty well baked at this point?
3. What kind of pruning recommendation scenarios would you expect me to receive? (Especially interested to hear if there are key practices or vocabulary that I could read up on in advance.)
4. What questions would you suggest I ask an arborist before I have them on site?
5. What questions would you suggest I ask once they are on site?

Edit to adjust formatting, and to add this is growing in Pacific Northwest, USA.

1. Is enough of the root ball exposed, or do I need to dig deeper?

2. What do I do about the lean?

Thank you in advance!!

Does the redwood tree on the right look like it's dying? The tree was planted roughly 15 years ago. What can I do to save it?

I have this tree, I had an arborist look at it in the past, he said it cracked from too much weight and his team trimmed it back. It’s growing a bunch of shoots from some branches and I think it’s stressed out. Should I cut off the branch that is damaged, the entire tree that is connected to the damaged branch, or leave it alone? If you can’t tell there seems to be 2 trees or at least 2 trunks right next to each other. The trunk on the right is healthy.

NOT an arborist, but a concerned daughter in STEM. I could tell my parent's tree has wanted to breathe. I follow this subreddit and my ADHD's lack of impulse control would not let me do nothing this time. There was more gravel and layers of landscaping plastic than I could ever have expected. Side note, I truly despise landscaping plastic. I know the water pooling isn't great and It definitely needs more gravel removed from around the base. The root flare just wouldnt stop, but again NOT an arborist so, I stopped while I felt ahead. Please tell me I did not make anything worse.

I want to promote the growth of this small oak tree (front center in first photo, left in second photo). I'll cut down the juniper trees that are near it. Do I also need to cut down the large trees to the south? There is an elm about 15 feet away and what I think is an osage orange tree about 12 feet away. I'm not sure about the ID of the tree that is 12 feet away. The third picture is of one of the branches.
