Which is best?
For complete weed control a concentrate will do as good a job as ‘ready to use’ and vice versa. Use them according to the kind of treatment required.
You may have noticed that weed killers are not made of the same chemicals. A lawn weed killer is a carefully selected group of active ingredients designed to kill a certain group of creeping and broad leaved weeds. Not all weed killers will kill all your lawn weeds hence you need to use a range of active ingredients to give yourself the best chance of good weed control.
I could give you a list of what kills what but as there is a limited range of active ingredients for home use then a little common sense is all that is required. Use one group of chemicals for ‘full lawn treatment’ and another group for ‘spot treatment’. If you only need to ‘spot treat’ then have two different ones on hand or when one runs out buy a different one to replace it.

New Lawns
When treating new lawns the manufacturers have the following recommendations:
- Scotts Verdone - 2 months after sowing though I'd be inclined to give it 3 months
- Vitax Lawn Clear - 12 months after sowing or turfing (must be strong stuff!)
Hopefully it goes without saying that growth should be good and the grass healthy before applying weed killer.
Always read the label. Use pesticides safely
