Roots are the lifeline of any tree or shrub. Most of a tree’s roots grow in the top 12″ of soil, with the fine roots in the top 3-5″ of soil. Careful monitoring can prevent several problems.
How root problems develop
• Too much or too little moisture
• Poor soil drainage
• pH too high or low
• Planting improperly – too high or too low
• De-icing salts
• Herbicide damage – weed control
• Construction on root damage
• Adding soil to roots
• Compaction (vehicles or pedestrians)
Warning signs of root problems
• Lack of root flare
• Fungal growths on roots or trunk
• Yellow, dwarf or light green foliage
• A heavy crop of berries, cones, or acorns
• Stunted twig growth
