If I Raise My Soil Levels Around My Trees Will They Die?

Q: If I raise the soil level around my trees about two feet, will they die? 

A: If you cover your mouth and nose with a wet washcloth, will you find it hard to breathe? Tree roots require the ability to “breathe”. They need to get rid of harmful gases generated in the normal process of root growth. They also need access to oxygen and carbon dioxide. In general, raising the soil level more than six inches, harms tree root respiration, particularly if most of the roots are covered. Consider using planters held above the soil on short legs if you want to grow flowers under the tree.
