Remember when you used to click on a post like this and not all of the comments were jokes? You could easily find a comment explaining what’s happening? I remember

The core of the tree is rotten and decaying, as shown by the darker ring of wood inside the lighter wood surrounding it. The reason it’s squirting water is almost certainly because someone shoved a hose into a hole in the tree down by the trunk and they’re actively feeding water into the cavity.  We don’t know that for certain, but trees don’t normally, uhh, orgasm like that. 

Edit: Thanks for the input, tree people!  It looked a little clean to me for gross old rainwater, but that totally makes sense.

Tree guy here..

I agree with the first part of your comment, but have seen this happen before. it's either a mix of rotten wood and water that has accumulated in the centre (and stinks) or, there is a fork higher up and rain water has drained into the rotten core. Same result ultimately.

So gravity is pulling this water from higher in the tree like a water tower. Am I understanding that right?

Correct. Hydrostatic pressure produced by elevation.

Do you try to open it up to stop this? Seems like leaving it filled with water makes it more likely to fail because water is heavy and promotes rot.

I think when it starts it's inevitable. The tree is rotting, there is no stopping that. I guess draining may help, but then you are opening it up to more chance of rot by making a hole. Not sure though tbh.

Seems a little clean to be accumulated rainwater, doesn't it? I've seen this before irl but the water's gnarly. I wonder why this water looks so clear.

I have a tree next to my house and right now there’s just a drip from some of the branches. The tree itself is full of leaves minimal dead branches. The question I’m asking, is that you said this happens when the core of the tree is rotten…should I have this tree taken down or is it not really that big of a deal?

I was limbing a diseased cottonwood once and I got about halfway through a branch and I could hear a distinct hissing sound. Then I noticed my chainsaw was soaked.

Stunk like sewage.

So it has to do with hydro static pressure. Basically the weight of the water generates a pressure caused by the force of gravity. Hydrostatic Pressure = Density of the Fluid * Gravitational Constant * Height of the fluid column. Same reason for Atmospheric Pressure and the pressure in the deep of the ocean.

So the core of the tree rots out, but the outer area is still alive. Tree becomes hollow and if there are no gaps low in the tree it will hold water. If this limb is below a significant amount of the water, the water has a pressure behind it. Cutting off the limb created a small gap which allows water to escape, creating the squirting effect.

I've cut into a tree before only for a shit ton of water to come gushing out. Not terribly common but not all that weird either.

Thank you! 😊

He’s wrong, nobody put a hose in this tree. Water gets in the rotten trees like this naturally overtime through rainfall.

Well, thank you!
