The best way is to start controlling tree height long before it grows too large, via careful pruning through the years. But that’s not always possible. If a tree has become too high or too large, use selective pruning to remove the most troublesome branches, one by one, without topping the tree. Gently shaping a tree like this can, over time, correct problems. You can also find growth inhibitors to spray on a tree to stop it from growing too rapidly, but use these sparingly if at all.

Early signs that a tree is struggling include premature leaf shedding and lesions or other strange markings. Peeling bark, dead or rotten branches on the ground, and a conspicuous lack of leaves can all be signs that a tree has started to die. By the time a tree starts leaning, it’s usually too far gone to save.

Yes, cutting a tree's roots can cause it to fall, particularly if major support roots are severed. In extreme cases, trimming roots can affect the tree's structure and stability. Many crucial roots are located just below the soil's surface. If you make severe cuts to roots more than 2 inches in diameter, you risk impacting the tree's water flow and its ability to withstand severe winds or storms. Even cutting roots less than half an inch in diameter under or outside the tree's canopy can cut off its water supply, causing it to decline, die, and eventually topple.

Palm tree stumps can take as long as seven to ten years to rot naturally. Whereas some tree stumps rot within a year, palm trees tend to last longer due to their deep root networks. Chemical rotting (described above) can help speed the process up so your palm tree stumps rot in under two months.
