3. As with all types of irrigation it is critical that the root balls are not allowed to dry out during the plant establishment period Initial postplanting irrigation is critical so it is necessary to over irrigate to ensure water transfer between the landscape soil medium and container plant root balls When planting sod or hydroseeded grasses establishment can be accomplished without supplemental overhead watering by making sure the soil is hydrated to field capacity prior to planting thoroughly rolling the sod to ensure optimum contact between the sod and the soil medium Use multiple start run times up to 10 times per day until the sod has knit into the soil Take care not to let the sod dry out during this period using multiple start times as described above to establish seeded or hydroseeded grasses 21 Landscape Dripline Design B Installation Procedures NOTES Installation Steps Assemble and install filter remote control valve and pressure regulating valve assembly ies according to detail numbers 1 and 2 p 23 Assemble and install supply header s according to detail numbers 3 5 4 and 6 p 24 25 Tape or plug all open connections to prevent debris contamination Assemble and install exhaust header s in accordance with detail numbers 7 and 8 p 26 Tape or plug all open connections to prevent debris contamination B Install dripline laterals Tape or plug all open ends while
