replacing hedges

[maxd]

My parents have a hedge in their back garden which backs on to some waste ground.  Last year my dad sprayed weedkiller in the waste ground to get rid of grass that was choking the hedge, but he succeeded in killing off part of the hedge as well.  If they remove this part of the hedge do they need to treat the soil before they can replant?  

Thanks

Most all commercially available weed killer purchased from Home and Garden supply stores work through the plant structure and do not affect the soil.  Actually, this is a requirement for manufacture of the chemical.  Additionally, most are only active for 24 hours.  The soil should be fine for replanting the hedge.  Tell Dad to be more careful next time (they love hearing that from their kids).  Weed killers shouldn't be applied during the heat of the day since they tend to drift more with the heated air.  Here, (U.S.) the aircraft agricultural applicators limit the application on farm crops to the hours before about 10:00AM or 70 degrees F so as not to have the chemical drift onto neighboring trees or homes.  The wind must be less than 5 knots for most applications...

Clanad is correct but beware. SOME weedkillers can live in the soil for us to 2 YEARS. Find out which type he used and check the directions on a bottle in the shop. Good luck
