Killing Lawn, Not Worms
So I spent the morning pulling 100 weeds and there's gotta be at least 1000 more to go (my backyard is 5,000 sq ft). As I'm doing this of course I'm concerned that too much of my life this spring will be spent pulling weeds. But worse, I'm worried that more weeds will move in before any grass seed starts to grow (it seems a little too early in the year for grass seed to start sprouting - I'm in the Toronto area).
Anyway, about half my yard is nothing but weeds and bare spots. Those areas worry me the most. Instead of trying to pull the weeds in those areas by hand, would I be able to kill them if I covered these areas with old carpet? I would leave the carpet down till late August, and then put some topsoil and sod down. Would that "technique" kill the weeds and not the worms - I'm really concerned about preserving the life of as many critters in the soil as I can.
Or would it be better to put some cardboard down, then some topsoil, and then lay some sod when it becomes available in mid May? By the time the cardboard broke down underneath the topsoil and sod, the weeds would be dead (wouldn't they?). Maybe using cardboard instead of using carpet would be healthier for the critters underneath. But another question remains - is it better to put sod down in May or in late August?
Thanks for whatever direction you can provide. I'm hoping one of these options will work.
