APPENDIX

Planting Guidelines

3. Trees 2.5” in diameter to up to 4” in diameter shall be provided with a minimum of three bubblers.

4. Trees 4 to 6 inches in diameter shall require four bubblers.

5. It is recommended for trees greater than 6 inches or larger to use drip rings for irrigation and tree establishment.

Good Example: Drip irrigation is great for established trees; it is low in water waste and applies it directly to the root system.

Poor Example: Drip irrigation wrapped around the tree trunk of an established tree. Water applied on the tree trunk and root flare can introduce disease and decay; restrict tree diameter growth and possibly lead to tree mortality.
