Common Tree Health & Disease Service Questions

When a palm tree no longer produces new fronds and old fronds start turning yellow-brown, that’s a sign the tree is dying. However, transplanted palm trees can show these signs for the first several months as they re-establish themselves. It’s best to keep watering and not give up on the palm tree until a couple of seasons have passed and you’re sure it’s not coming back to life.

Covering exposed tree roots can be safe, or even beneficial, when done correctly. Adding a layer of mulch or soil can protect roots from erosion, maintain moisture, and moderate soil temperature. However, it’s important to avoid piling soil too high around the tree’s base, as this can suffocate roots and harm the tree.

You can tell if palm tree fronds are healthy by looking at the color. A healthy frond has a deep green hue. However, yellow fronds or yellow spots indicate your palm tree may have a nutrient deficiency. Brown means the fronds have died and should be trimmed off the tree.

Any type of construction that damages a tree’s roots via soil compaction can be dangerous, and is one of the primary causes of mature tree death in residential areas. Simply putting lots of weight on the ground around the tree, like construction supplies, trailers, and equipment, can kill roots near the surface. Of course, installing new foundations, patios, or utility lines can cut through nearby tree roots. Accidentally striking a tree with equipment or supplies is rarely a problem, but can cause damage of its own, too.

Palm trees are unique in that their roots don't grow straight down; they grow horizontally. Typically, palm tree roots go down between 12 and 36 inches deep. The roots grow far and wide from the base of the palm tree to absorb as much water and soil nutrients as possible. In addition, the horizontal roots are also very strong—keeping palm trees stable and helping them sway during storms.
