A. Prepare the initial planting hole as illustrated below. This is based upon the combination of desired barrier diameter, depth and gravel. Consider if drainage devices or amendments are needed to correct any adverse soil or planting conditions. Please note that we recommend digging an additional 12" (30cm) for largest possible rooting area below the depth of the barrier, and then compacting this space again, either with the original excavation materials or soil amendments as necessary. This ensures that the roots will be able to penetrate the ground below the barrier, yet will not settle below grade with watering.

B. Assemble the appropriate number of DeepRoot Universal Barrier panels. The vertical root deflecting ribs on the panel must face inward, toward the root ball. (This is very important, otherwise the roots will become girdled by traveling around the smooth walled surface.) 

C. Next place the barrier in the center of the planting hole, keeping in mind that the double top edge of the barrier should be positioned approximately 1/2" (13mm) above grade. This helps retard potential root overgrowth. Failing to position the top edge above grade can allow root over-growth which can lead to uprooted hardscapes.

D. Backfill and compact with soil inside the barrier or planter to the level where the bottom of the root ball will be when positioned correctly with the crown of the root ball approximately 1" (26mm) above grade.

E. Remove the tree from its container, or cut away the top portion of burlap and position in the center of the barrier or planter. Complete the backfill of the soil inside and gravel outside. Distribute evenly to maintain the shape of the barrier and compact the backfill every 4"-6" (10cm-15cm). Roots will die quickly if left exposed to the elements so keep exposure of the roots to a minimum.

F. If staking or guying is required we recommend using the soft, safe and economical alternative to traditional wire and hose, ArborTie. If the tree(s) will be subject to maintenance work such as lawn mowing or weed trimming we strongly recommend the installation of ArborGard+ Tree Trunk Protectors which are placed around the base of young trees to protect them from damage by weed trimmer, lawn mowers and small rodents.

G. Water and follow proper tree maintenance practices. Trees do require care and nurturing after planting. Consult with your local supplier for proper care procedures for the species you are planting. The planting instructions given here are by no means a comprehensive guide. Rather they are general guidelines to planting with DeepRoot Barriers and a survey of current planting methods. Conditions will vary however and it is recommended that an Arborist be consulted before planting.
