Pine Tree Health

• Upvotes

Hello!

We have two pine trees in our backyard and over the last year or so we've noticed some of the branches and sections of the trees look to be in rough shape. To an untrained person I would assume that these branches are dying? Do we need to cut some of it away for new growth? Maybe hard to tell in pictures but hoping it's not parasite related or something in that realm.

These trees provide a natural buffer from neighbors so we want to keep them around as long as possible!

We live in Central Iowa and are coming out of a very wet September.

Home was built in the 90's and as far as I know these trees have been here ever since.

If I need to provide further pictures I can!
Thank you!

Eastern Redbud in Central AR

Hey, folks! Any idea why my tree would look like this? In its second or third year, never seen it so bad. Under watered or over watered? Just the scorching heat we've been having? I think my neighbor's wife waters it every night or two when she waters hers. (I'm on the right)

Central Iowa - Flamethrower Redbud

We planted this redbud about 18 months ago.
It’s growing nicely but I have a concern about the leggy, floppy leader at its top.

The leader is rather long and curves downward

Should I leave it? Splint it? Prune it?

I don’t plan to do anything till the leaves fall but need help about how to best handle it.

Due to how the branches grew on this dogwood, water is pooling between them and it seems like it's getting deeper over time. Anything I can or should do here?

Gardener butchered the trees in our yard

TLDR: Is there a way to make this better? What can I say to the landlord?

Background info. We own a house in another state, had tree work shortly before we moved by certified arborist. Trees looked great post trim.

Moved here this spring for a job. Rented this house at an exorbitant rate. Loved the back yard, tree in picture was heavily overhanging the roof to house and garage, provided a lot of shade, but wasn’t great for structures. Obviously the trees are old and were pollarded for years, but when original owner died (or perhaps sometime before) this had stopped. I don’t think they’ve trees were trimmed for the three years landlord owned the house. I mentioned to the landlord that he should look into getting the trees properly trimmed when the time was right.

I came home from a camping trip with my toddler to this, and a tree in front that looks equally as bad. It is bad? Right? I mean I don’t like the way the garden goes the shrubs and bushes either just trimming never pruning so you get dense dead leafless areas.

I know at its core this is not my circus, but my back room is now several degrees hotter, my patio lost its shade. And the trees which brought me such joy look like shit.

Help?!

ELI5 - How do I get my Norway Spruce Back to Health? Is it Even Possible?

Thumbnail gallery
2 Upvotes

ELI5 - I'm in eastern upstate New York, about 10 miles southeast of the Adirondacks

Not sure what to do as I've never taken care of a tree. But I like a project so I'm going to try

Tree is about 55' tall and the trunk is 6.5' in circumference, just above the dirt

I cut off some of the lower branches that only had pine needles on the very end of the branch. Was that bad? Or can I cut off the rest that are like that? I just assumed the tree was dying of old age so may as well, now I'm not so sure

Soil is sandy up here, maybe you'd call it loamy? I included a pic of the soil. Tree gets lots of sun starting with sunrise. We get tons of rain up here. Cold winters

I took included some pics of the fungi that I found growing in the soil. Not sure if it matters

In the pics you can see a mulberry and a locust tree growing right up through the branches of the spruce. Are they harmless or are they hurting the spruce?

I have spent HOURS ripping up Oriental Bittersweet. The vines but also the extensive root system. It had been growing all over the tree. I killed it but the dead vines are still wrapped all up the tree. Is that bad? I don't feel safe climbing up the tree

Moss and some weird blue stuff growing on branches. See pics

Any hope that it can grow back its needles and its "fullness". Or is it a goner?

If you can tell me what to do or direct me to helpful links that would be great! LMK if you need more pictures!

Gas company wants to trench

Thumbnail gallery

Trying to get gas to the house from the street, and the guy says too many rocks to mole through so they would need to trench 2'. They want to go right between the biggest ones which seems like a terrible idea for the trees.

The red line is where I'm thinking would be best. The thin tree in the foreground right next to the red line is already nearly dead so it's fine to go, and the short one past that is also not in great shape so I'm fine with it if it doesn't survive. But that still passes within 5' of another tree and within 10' of those two bigger ones.

How much of a gamble am I in for?

Hey everyone, question about the health of this tree. I moved into this home last year and had to trim some rotten limbs off of this bad boy. I believe it is some species of maple but am unsure.

The cracked limb is from a storm a few weeks ago. And the fungus/mushroom growth is new on one the dead limbs that was trimmed.

Should I cut my losses and have it cut down?

Ecological impact of Norway maples

Thumbnail gallery

For the longest time I thought this tree was a sugar maple. After some research it appears to actually be a Norway maple. We live in an urban neighborhood of Missouri, and only have room for two trees on our lot. We thought we had a tree that supported local wildlife and insects, and then to learn the Norway maple is actually invasive was a bummer. I'm not going to cut it down and replace it just because it still provides excellent shade in the summer, but I'm not going to lie I'm going to look at differently now that i know its technically invasive.

Do I have too much to prune?

Post image

Silver maple. I believe four years old. Probably 12-14ft tall. The middle branch is by far the tallest, with two smaller branches, one on either side. I've kept the smaller ones trimmed back (they go about half-way up) with the intention of taking them off completely, but I'm a little nervous it may be cutting out too much mass to do without harming the tree.

Are we in deep trouble?

Last year I was asking about this tree and if there were issues with the roots being too close to the house. Now I have a new concern… Compared to what it looked like last year it looks like it’s dying. I did have to dig up one of its big roots that was next to the house but otherwise nothing else has changed. Any thoughts?

Attached our photos of what it looks like now and what it looked like last year.

Best way to prune this tree to minimize risk of damage when Super El Nino comes to Los Angeles?

Thumbnail gallery
0 Upvotes

I bought this house back in July and it has grown significantly (see last picture for what it looked like back then).

With Super El Nino coming to LA soon, I'm worried about damage to the tree and my house/neighbors' houses if branches fly off or something like that.

I'm getting quotes from local arborists that are licensed, bonded, and insured. But I wanted to ask this subreddit for advice to ensure the arborists I talk to are competent and don't try to upsell me on things.

Also, once someone prunes the tree, is it possible for me to maintain the tree myself? If so, how could I do that?

Maple with root rot & trunk cavity in wet soil — Seeking advice on treatment & structural risk

Thumbnail gallery
1 Upvotes

.

Tree & Site Context:

Tree Type: Maple

Location / Climate: Northeast US (frequent rain / wet soil)

Conditions: The tree was previously receiving regular sprinkler water (sprinklers have now been turned off completely), but recent heavy rainfall keeps the soil quite damp.

Issues Noticed: Confirmed/suspected root rot and a pre-existing trunk cavity / hole.

Questions:

Fungicide / Treatment: Given the wet soil and frequent rain, I’m considering a systemic basal bark application of Potassium Phosphite (e.g., Agri-Fos + Pentra-Bark) rather than a soil drench. Does this sound like the right approach for root rot recovery under wet conditions?

Trunk Cavity: The tree has an existing hollow/hole in the trunk. I know not to pour anything inside it, but should I be concerned about moisture pooling in there during rainstorms?

Structural Risk: With both root rot and a trunk hole present, what are the key red flags I should look out for regarding structural stability/fall risk? It is in my backyard, tree is mostly hanging towards neighbour's farm.

Pecan Trees with Sudden Limb Drop.

These are trees on my children’s school playground in central Texas. They’ve dropped 3 good-sized limbs in the past two months. Supposedly a certified arborist told them to do this. I assumed the mulch was supposed to extend to the drip line with no tree ring. What say you all?
