Boost Tree Health |
 |

and stimulates root development. This
increases root-to-crown ratio which
can increase stress resistance and
speed recovery from stress brought
on by drought, pollution, and
temperature extremes. |

reduction and lets you: |
• |
Reduce growth where trees are planted
too close together or in tightly landscaped areas. |
• |
Manage growth of trees planted too
close to homes, decks, foundations,

• |
Maintain scenic view with less trimming. |
• |
Manage size and improve vitality of trees
in vaults, along sidewalks, in parking
lots, or in interior spaces. |
• |
Extend trimming cycles, reducing labor
time and expenses. |
• |
