Many homeowners will defend their yard with as much dedication as a wild animal staking out their territory.

A person's yard can mean many things to them; it is their own little patch of the great outdoors, a space to relax, or a way to show off to neighbors and passersby their enviable landscaping skills. Above all else, it is a piece of land they can call their own, and within reason, they should be allowed to do what they want with it without others encroaching on it and invading their space.

Without a doubt, it takes skill and dedication to keep a yard looking good no matter what the gardener's preferred aesthetic is. Lawns require constant maintenance, so much so that lawn care is a $76 billion business in the US. On top of that, any kind of flowers, trees, and even decks are going to require attention to keep on looking their best.

With this in mind, it is not that surprising that people can get a little territorial about their gardens. It takes a lot of time and money to keep on top of them, and homeowners want to be able to enjoy the fruits of that labor without interruption. So long as they are maintaining their yards in a way that doesn't have a negative effect on others, everybody deserves to be able to appreciate that space in peace. Their neighbors should be able to mind their own business and keep their own maintenance practices to their own property.

Unfortunately, neighbors getting into disputes over their yards is a tale as old as modern homeownership. Some people are nosy and disagree with how their neighbors choose to keep their outdoor space, and others care so little that it starts to cause an issue for those around them. It's also not uncommon to feel like next door's maintenance (or lack of it) somehow has a negative impact on yours, leading to all kinds of rivalries and arguments that can become pretty ugly if they are not kept in check. At the end of the day, these are just random patches of grass, but they are their patches of grass. They are allowed to feel protective over it if they are given a good reason to be.

A or B: My neighbor's $3,800 robot mower kept crossing into my yard and damaged my garden. I added $95 of edging on my side, and now he wants me to pay for the repairs

My neighbor and I share a straight property line between our front yards. Last spring, he bought a $3,800 robotic mower that uses a boundary wire. He was pretty excited about it and showed me how he could control it from an app.

Around the same time, I planted a small native pollinator garden on my side of the yard. It was just some native flowers and grasses that cost a few hundred dollars and took me a weekend to put together.

Technology can be wonderful when it comes to saving time on arduous outdoor tasks, but that doesn't mean that it doesn't have its downsides. This is what a pair of neighbors quickly found out when one bought an expensive robot lawnmower for his backyard.

The mower was supposed to stay within strict boundaries, but it kept straying into the neighbor's yard and damaging the pollinator garden they had invested heavily in. They knew they had to take action against it, but that also ended up providing a further headache for everyone involved.

A few weeks later, I noticed his mower had crossed over the property line and damaged some of the plants. I sent him a photo, and he apologized and said he would adjust the boundary settings.

The problem only began to escalate.

The same thing happened again a few times over the next month. Each time he said he would recalibrate it, but eventually the mower went further into my yard and damaged a larger section of the garden. My doorbell camera captured multiple instances of it crossing the property line.

I checked the property records to confirm the boundary and installed $95 of metal landscape edging a few inches inside my own yard to protect the garden. The edging was completely on my property, and there are no HOA rules against having it.

About a week later, my neighbor came over and said his mower had hit the edging and damaged the blades. He showed me a repair estimate and also asked me to cover the cost of renting a replacement mower while his was being repaired.

The neighbor wasn't happy with their solution to the issue.

He believes I created a hazard near the boundary and should have warned him before installing it. I think his mower repeatedly entering my yard and damaging my plants is what caused the whole situation. Another neighbor told me I should just split the cost to avoid creating bad blood over a lawn dispute.

A) I pay part of the repair cost and move the edging back to give his mower more clearance. A few hundred dollars is not worth creating a long- term feud with a neighbor. B) His mower crossed onto my property multiple times and damaged my garden before I installed anything. I refuse to pay for the mower repairs and use the camera footage if he tries to make me responsible.

He wasn't considering the damage the mower had already done.

Pawtuckaway B and send him a bill for the cost of the damaged plants from your garden. If you want to keep relationship then bring up how you have several hundred dollars worth of damaged plants that you didn't request that he pay so call it even and move on.

cenosillicaphobiac B. His failure to properly adjust the boundaries of the mower was 100% the cause of his mower getting damaged when it once again tried to encroach on your property, destroying it. Hit him with the tally for the plants that his mower destroyed and see if they cancel each other out.

treehuggerfroglover C.) You pay nothing for the damage his mower sustained while crossing into your property, AND he pays you for the estimated cost of the damage the mower did to your plants

Conversation hadn't got them anywhere.

DeniedAppeal1 B. You gave him notice on multiple occasions and the problem just kept getting worse. Clearly talking to your neighbor was not a viable solution.

GTS250 He has kept mowing your property you didn't want mowed. Sharpening some blades is cheap at the price.

CrazyParrotLady5 B. This man knew his robot mower was crossing boundaries and did nothing to prevent the damage from happening. You fixed the problem by adding a boundary. This is his mower and his responsibility. You did nothing wrong.
