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.

The best way to protect tree roots is to avoid the roots entirely by excavating outside the root radius of the tree. For nearby projects, it’s a good idea to construct a temporary retaining wall. But that’s not always possible, depending on the project and the root system. In these cases, consider using alternative equipment like an auger to tunnel under the ground.

Remember, tree roots can damage nearby cement foundations as they grow. If a tree is close enough to interfere with large excavations, it may be better to remove the tree than risk future problems.

Some fast-acting products can rot a tree stump in four to six weeks. Keep in mind, these products contain harsh chemicals that may prevent regrowth in the area. Other products, like fertilizer that contains lots of nitrogen, can enhance the process and rot a stump in about a year. (This is compared to the ten years it can take naturally for a stump to rot.)

If it’s your property, then you can plant a tree near power lines, but it’s not the best idea. Any vegetation that grows within 10 feet or so of power lines will fall under the responsibility of the utility company, and they may trim or remove it as necessary. If you do move forward with your plan, try to choose a smaller ornamental tree, plant it as far away from the power lines as you can, and keep it trimmed to avoid future problems.
