什么是"power rake"? Rona or Home Depot 的网站都找不到.听说Moss Control对狗有毒,有人用LIME杀MOSS吗?
Yes, you should be able to find the power rake (a more formal name may be called power dethatcher) in the Rental Section in both Rona and Home Depot.
Generally speaking, you don't have to re-seed the lawn after you power rake it. But it's a good time for you to fertilize it with lawn food.
Moss Control should not be very harmful for dogs or human, but some people do not like it. Be careful while you apply it to your lawn if there are kids around.
