Greetings,

I have a large sand box playground in my back yard about 25' x 40'. Have
swings and slides and such for the kids. Last summer and fall I was very
busy and could not find the time to keep it weeded. Consequently, it got
overgrown and rather messy. This year I do not want to let it get so out
of hand.

I have pulled the weeds already, but is there anything I can do to the sand
to keep them from coming back? Or at least minimize them? Would tilling
in some lime help? I wanna kill the weeds there, not the kids.

Thank You for your time.
