Premature failure of container irrigation systems due to clogged inlet holes are a thing of the past with BioGuard squares from Planter Technology. Simply drop the 3" square of coated fabric into each water inlet cup of any container irrigation system. Trifluralin, the active ingredient, is released from the nodules on the fabric and forms a root barrier just above the water inlet. Roots stop as they grow into the zone. No more digging up plants that have clogged their own irrigation systems, or root pruning plants with aggressive root systems. Long lasting - won't wear out, break down, or decompose.For Exterior and Interior applications. Saves hours of long-term labor. 6 squares per pack. |
