Holden vehicles, in addition to nameplate, are designated by a series code. For example, the 1971â1974 Holden Kingswood has been assigned the series code  HQ , and the 2002â2004 Holden Commodore,  VY . Often these series codes are not arbitrary.In the case of the VY above, the V stands for the GM V platform that underpins it.he VY series of Holdens were not restricted to the Commodore; VY Berlina and Calais cars were also marketed.
Water the grass seed for 5 to 10 minutes immediately after seeding. Set the sprinkler timer to water the grass seed 5 to 10 minutes three times a day, beginning before sunrise and ending in midafternoon. Continue this cycle for one week to 10 days or until seeds sprout. Check for puddles, runoff and dry spots in the soil.
New grass won't grow where fresh herbicide exists. Using a pre-emergent weed killer on your grass helps keep pesky weeds from marring the lush, even look of your lawn. Whether you use granule or spray types, don't plant grass seed for several weeks after applying the herbicide.fter you seed, wait until you've mowed the new grass at least four times, which could be six to eight weeks after seeding, before adding herbicides.
