What can I use to kill weeds on a tennis court and also on a long driveway. I've tried roundup but it just doesn't do the job. The weeds are back in a short time. I'd really appreciate some help.
Thanks.
Hey Rae, Round Up is only effective on plants which are actively growing and has no on-going residual value. You need one of the "Long term" herbicides.
Pathweeder from Yates is designed to sterilise the soil for a whole year.
Here's a link to the Garden Shop where you can purchase it:-
