Can i give weed slayer contained by bright sward 4 weeks antiquated?
Answers: as long as it is not a preventer. a preventer would prevent the seeds from germinate. but a killer works by absorbing into the larger leaves of weed. the grass leaves are typically to small to absorb ample killer to inflict damage. but if you of late seeded you might want to make available it another couple of weeks. try pulling the weeds instead right immediately.
Yes you would want to wait until the blades are longer. Any weed assassin will but a strain on seedlings or your grass.
Give a couple months and try a selective weed murderer.
