Can You Trim a Neighbor’s Hedge That Crosses Your Property Line?

Unsightly hedges creeping onto your property can be quite the nuisance—especially if you’re someone who prefers tidy landscaping. Not only is it an aesthetic issue, but it can also quickly lead to disputes with neighbors. So, can you trim your neighbor's hedge, or should you leave it be? We spoke to legal experts to get to the bottom of this conundrum.

The Legality of Trimming a Neighbor's Hedge

When it comes to cutting a neighbor's hedge on your property, local and state laws vary. “In general, the law allows a homeowner to cut back any branches or leaves that hang over the [property] line, as long as you stay on your land,” says Danny Karon, university lecturer, trial attorney, and author of Your Lovable Lawyer's Guide to Legal Wellness.

Therefore, you don’t need to get your neighbor’s permission to trim what is on your property. “It just has to be reasonable, and you can’t trim anything that's fully located on the neighbor’s property—so it’s always smart to just check your local laws first,” Karon warns.

However, it's always best to chat with your neighbors before breaking out the hedge trimmer. “Ownership of trees and hedges is determined by the location of the trunk, not the branches,” says Jase Jacobson, arborist and owner of Clean Cut Trees. “Even if your neighbor's hedge is reaching way over your property line, it doesn't belong to you. If you kill the plant in the pruning process, your neighbor may have grounds to claim damages.”

Your right to prune also comes with additional rules to follow, according to Mindy Stern, partner at Schwartz Sladkus Reich Greenberg Atlas LLP—rules that could land you in court if ignored. “For example, you must stay on your side of the property boundary,” she says. “You cannot step onto your neighbor's land or reach over the fence to trim without explicit permission.”

Should You Ask First? 

“Whether it’s legal or not, it’s always a good idea to just be cordial and have a calm, polite conversation with your neighbor,” Karon says. “This can often avoid a lot of headaches down the road.”

In fact, coming to an agreement with your neighbor ahead of time can provide several benefits during property line clearance. “You can avoid confrontations, get permission to access their property, and preventively prune past the property line,” Jacobson says.

How to Ask

It's important to be neighborly. “A five-minute conversation is always cheaper than months or years in court,” Stern says. “Start by asking nicely and without any demands. If the overgrowth is on both sides, offer to split the cost of trimming.”

Of course, sometimes neighbors are unreachable or perhaps unwilling to discuss. “In that case, sending a formal, certified letter outlining your plans will be required,” says Gilbert Morales, real estate attorney and associate at Williams Teusink. “Regardless of how you communicate with your neighbor, you want to convey that you will be trimming the hedges only to your property line and no further. You will also want to share the date and time that the trimming will occur. The more coordination you can achieve with your neighbor, the better the outcome.”

If you’re still unsure about your rights, Karon says a quick call to a property lawyer can go a long way. “You should put your concerns in writing, and for bigger jobs, hire a professional to do the trimming who might also have more information on local ordinances,” he says. “Make sure to take a lot of photos, document everything, and put agreements in writing.”

Tips for Trimming a Hedge

The most common hedges planted along property lines share several important characteristics, says Jacobson. “Evergreens provide privacy and greenery during all seasons, are tall or fast-growing, and resistant to extreme heat and cold,” he says. 

These common species can be broken up into two basic groups. “Coniferous, such as arborvitae, juniper, and cypress,” Jacobson says, “and broadleaf, such as laurel and camelia.” 

Each group requires distinct pruning practices to maintain a healthy canopy and prevent overgrowth. He provides a few tips for each grouping but suggests a good rule of thumb: "Regular trimming makes for easy trimming."

Coniferous Group

When it comes to coniferous hedges, new growth occurs at the tops and tips. “You must avoid taking too much material while trimming the sides,” Jacobson says. “If you cut too deeply, leaving sticks instead of greenery, it is unlikely that the tree will recover the exposed area."

Instead, there will be a permanent bald spot. “Though it's unlikely to kill the plant, it's unsightly and exposes the tree to potential sun damage,” he says. “You only need to trim the sides once each year.”

Broadleaf Group

New growth follows the sun. “This means you can take more material from these species, but it is easier for the hedge to become unbalanced or lumpy,” Jacobson says. “If any bald spots occur during pruning, it is likely that the hedge will recover. However, the parts of the hedge that receive more sun will grow much quicker. I recommend trimming the sides twice a year.”

When to Call a Professional

Tree care and landscape companies can provide a professional solution to property line problems. “They are experienced in proper pruning techniques, will remove the debris afterward, and are well-versed in state regulations for property line clearance,” Jacobson says.

When dealing with hedges over 10 feet tall, consider using a tree care company, as they will have specialty equipment for working at higher elevations. "In general, if the property line clearance is extensive or taller than you are comfortable reaching, hire a local company,” he says.
