Linear Applications:
In a linear application, the tree root barrier should be installed per the directions below:
1. Before the tree is planted, connect the root barrier panels to a length of 6 feet. If multiple trees or a row of trees are to be planted, be sure to allow the barrier to extend at least 3 feet to on either side of the first and last trees in the row.
2. Dig a trench along the sidewalk or patio centered on the planting site, 6 feet long and appropriately deep so the top of the root barrier will be 1/2" to 1" above the finished soil grade or flush with the level of the sidewalk or patio, whichever is lower.
3. Place the pre-assembled panels in the trench. Center the root barrier on the planting spot so it extends for 3 feet on either side of the tree trunk. Be sure that the ridges on the root barrier panels are facing the tree. Double check that the root barrier panels are 1/2" to 1" above the soil line.
4. Backfill while taking extra care to keep the root barrier in place.
