I have a bad clover problem here in the DC area. As much as I hate to use

Do you have black medic? The most effective time to treat weeds is in
the spring.

Would I do damage to my grass if I sprayed a weedkiller on right before we
left, so as to minimize our exposure to it?


Follow directions carefully. Use sprays on a windless day.
