1. BARK
Outer bark, provides protection. Inner bark or Phloem, moves food (sugars) and hormones. |
2. WOOD OR XYLEM (All tree wood)
Sapwood, contains active conducting vessels in the outer three rings and is used for water and nutrient movement and food storage. Drilling into sapwood disrupts the negative pressure required for effective nutrient movement. |
3. CAMBIAL ZONE
Area between the bark and the wood (not shown to scale). Cambial zone accepts injected chemicals which are then absorbed by the outer ring of sapwood, without damage to the sapwood. |
4. PROTECT YOUR TREES
The Direct-Inject systems inject chemical directly through the bark without damaging sapwood. |
5. STOP DRILLING DAMAGE
Drilling wounds compartmentalize, permanently damaging the tree's ability to move and store nutrients. |
