Q&A Home

Janie from Port Ludlow, Wa writes,

We have a large yard. Is there a weed control product (Caseron) that lasts a year?

If so, which month is best to apply? The Caseron does not last an entire year. I know you need to put it down before the weeds begin to grow again, but I'm hoping we don't have to apply it twice a year. It sure helps prevent weeds growing; which saves on Roundup usage. Thank you for answering the question and any advice you might have.


Unfortunately there is not a weed control like Casoron that will provide you year long prevention from weeds growing, the only products that provide year long control are bareground herbicides such as Pramitol. Casoron is labeled to give season long control, but you will need to reapply because it does not have and post emergent qualities. Dimension 2EW gives pre and post emergent control for labeled weeds.
