if i covered the lawn beside top soil and spread grass seed would that murder the dandilions
Answers:    No. They would be delighted to come up right through the topical soil and new grass.

Either verbs them out by hand, win one of those dandelion forked-knives that cuts the root off vast underground, or get a broad-leaf weed murderer spray that should easily wipe out them.,
No, dandelions are a root plant. If they're not de-rooted, they'll come back. Get a weed contract killer, should do the trick.
