You noticed it after the last heavy rain. The grass and soil around the base of the tree look different. Something is pushing up from underneath. There might be a crack running through the ground near the roots, or one side of the tree base looks like it is rising while the other side looks like it is sinking. It is not something you remember seeing before and now you cannot stop looking at it.
This is worth paying attention to. Here is what is actually happening and what it means for your tree.
What You Are Actually Seeing
The ground lifting or cracking around the base of a tree is almost always related to the root system. When you see soil pushing up or separating around a tree, it usually means the roots on one side are moving. And roots move when the tree is moving.
In most cases what you are looking at is the beginning of what happens when a tree starts to lose its grip on the ground. The root plate, which is the network of roots that anchors the tree in the soil, is shifting. One side lifts as the other side pulls down. The soil above those roots moves with them.
This does not happen all at once. It happens gradually, and by the time you can see it from the surface something has already been going on underground for a while.
Why Summer Rain Makes This Worse in Spring Hill
Hernando County gets significant rainfall through the summer months and into September and October during storm season. That matters because saturated soil behaves differently than dry soil.
When the ground is waterlogged the soil loses much of its ability to hold a root system in place. Roots that were reasonably secure in dry conditions have less resistance when the soil around them is saturated. A tree that seemed stable during the dry season can start showing movement after a stretch of heavy rain.
This is why homeowners often notice the ground lifting around a tree after a significant rain event. The soil shifted when it was saturated and when it dried back out it did not return to exactly where it was. You are seeing the evidence of that movement in the surface of the ground.
A tree that is already showing root movement before storm season is worth having someone look at. Once serious wind arrives it does not take much more to finish what the soil saturation started.
Is This Always an Emergency
Not necessarily, but it depends on what is going on with the tree and where it is sitting on your property.
A tree that is showing slight ground movement in an open area away from structures may have some time. You want to monitor it and have it assessed but it is not always an immediate crisis.
A tree that is showing ground movement and is sitting near your house, your pool cage, your fence or your neighbor’s property is a different situation. The risk changes completely when there is something in the fall zone. A tree that shifts enough to come down does not come down slowly. It comes down all at once and it lands wherever physics takes it.
The same applies to trees that are showing other warning signs alongside the ground movement. A tree that is also leaning noticeably, has dead sections in the canopy or has bark damage near the base is showing multiple signs of instability at the same time. That combination is worth acting on.
If your tree has been leaning a little more each year that is a related pattern worth understanding. We wrote about why trees keep leaning a little more every year if you want to read through what drives that.
How This Is Different From Normal Root Exposure
Sometimes homeowners confuse ground lifting around a tree with surface roots that have simply grown up over time. These are related but different things.
Surface roots that have gradually become visible as the soil around them compacted or eroded are common in Spring Hill and across Hernando County. They can be a nuisance and a tripping hazard but they are not the same as active ground movement. If the roots have been visible for years and nothing has changed they are probably not indicating instability.
Ground lifting that is new, that appeared after a storm or rain event or that you can watch changing over weeks is different. That kind of movement is active, not just the slow exposure of existing roots.
We wrote separately about why tree roots start showing above the ground if you are trying to figure out which situation you are dealing with.
What to Do If You Are Seeing This
Take a few photos and note when you first saw the change. If the movement is happening near a structure or if the tree is large, call someone and have it looked at in person. There is no way to assess root stability accurately from photos alone and there is no substitute for someone walking the property and looking at the tree from every angle.
Spring Hill Tree Specialists handles tree removal for trees that have lost stability including large trees near structures.

Frequently Asked Questions
Is ground lifting around a tree always a sign it needs to come down?
Not always. It depends on the tree, how much movement is happening and what is in the area around it. Some trees show minor root movement and remain stable for a long time. Others need to come down. The only way to know is to have someone assess the specific tree in person.
Can heavy rain cause a tree to fall even if it looked fine before?
Yes. Saturated soil reduces the ground’s ability to hold a root system in place. Trees that were stable in dry conditions can shift or fail when the soil around them is thoroughly waterlogged, especially if the root system was already compromised in some way.
How do I know if the ground movement is new or has been happening for a while?
Look at photos of the area if you have them. Ask neighbors if they have noticed anything. New movement often coincides with a specific rain event or storm. Movement that has been gradual over years tends to look more settled, with grass and vegetation growing over the affected area.
My tree is leaning and now the ground is lifting on one side. How urgent is this?
That combination is worth addressing sooner rather than later, especially if the tree is near a structure. Leaning combined with ground movement on the side opposite the lean is a sign the root plate is shifting. Have someone look at it before the next significant storm.
Should I call a tree service or a different type of professional for this?
Start with a tree service. We can assess the tree and the root situation and tell you honestly what we are looking at. If the situation involves structural damage to your property from roots that is a separate conversation but the tree assessment is the right first step.
Not Sure What You Are Looking At? Have Someone Come Out.
Ground movement around a tree is one of those things that is hard to evaluate from the outside. A photo does not tell the whole story and neither does a description. If you are seeing something around your tree that did not used to be there, the straightforward thing to do is have someone walk the property and look at it in person.
