Unfortunately, palm tree stumps are one of the most difficult types to remove due to how their roots grow. Unlike other trees, palm tree roots grow horizontally and vertically. Palm tree roots grow as deep as three feet into the ground, although soil and growing conditions could mean they go as far as 50 inches into the earth. 

If you want to be able to repurpose the grass in the area where you removed a stump later, you’ll have to dig quite deep—and perhaps wide—to trim away all the roots.

Carefully pruning small roots no thicker than three inches in diameter won’t harm the tree. However, cutting larger roots may impact the tree's stability and nutrient absorption. It's advisable to consult an arborist or tree care professional to evaluate the root's size, the tree's health, and the potential impact of cutting. Proper tree pruning techniques and timing can minimize damage, but larger root removal may necessitate expert guidance to avoid compromising the tree's overall health and stability.

Trees should be pruned every two to five years, depending on its age and type. Young trees should be inspected and pruned every two to three years. Mature trees should be inspected and trimmed every three to five years, and fruit trees should be pruned annually with a careful eye on seasonal growth. Evergreens typically don’t need pruning, unless branches or limbs are damaged, diseased, or harboring pests.

If tree branches cross well into your property line, in many cases, these branches become part of your property, and you can trim them up until your neighbor’s property line. However, this issue will vary based on local ordinances, so you should do your research before making any decisions. Better yet, speak with your neighbor about how to handle any tree issues. 

If you don’t mind the branches, you can leave them be, but if they’re becoming a hazard, it’s definitely worth having a conversation.
