I find that very hard to believe. On limestone gravel it will be netralised on contact. It might just about work on a good day in full sun on particularly feeble weeds. Just a guess; wouldn't sub-zero winter soil temps in Ontario probably kill any shallow rooted annual and perennial weeds on a gravel drive (laid over a solid subbase, and kept clear of insulating snow). So in the growing season there would only be newly germinated seedlings which are very vulnerable. Janet |
