We recommend using a temporary supplemental overhead irrigation system to establish plant material in conjunction with the subsurface system.
Temporary supplemental overhead irrigation can be stopped once roots have grown into the irrigated zone. Approximate grown-in periods include:
2-6 weeks for shrubs, perennials, and groundcovers during the growing season or until plant material roots have established in Eco-Mat irrigated zone
2-5 weeks for sod during growing season or until plant material roots have established in Eco-Mat irrigated zone
When installing sod, ensure proper contact between the sod soil and the wetted backfill soil by rolling sod with a sod roller after installation. Temporary supplemental overhead irrigation is highly recommended when sod is first installed to promote root growth and prevent the drying and shrinking of the sod rolls. Temporary supplemental overhead irrigation is necessary when germinating seed. Run overhead and subsurface irrigation together to ensure proper establishment and root growth. Cease overhead irrigation when roots appear to be established. When installing a plant that has a root ball deeper than the desired Eco-Mat depth, cut fabric in an X or H shape and fold upwards away from the soil. Excavate below the mat to the depth of the root ball and plant normally.
