Weedkillers based on paraquat are not persistent - they are inactivated on contact with soil. The trade name in the UK is Weedol.
Glysophate based weedkillers are another option. They rely on absorption through the leaves and eventually kill the roots. Again not persistent in the soil but needing 2/3 weeks to penetrate and kill perennial weeds.
Avoid total herbicides, sometimes called brushkillers. They are truly nasty chemicals, very persistent in the soil and sometimes containing traces of dioxins.
A good garden centre will advise.

Surely you might think ........The label on the product will tell me the answer. Reasonably you might understand why they made the chemical, and deduce some are meant to kill all growth for a long period of time and some would be developed for agricultural uses ,so that only things planted after application will grow.Some will only kill certain plants. etc.
If you dig up the area after you spray it you will expose new grasses and weeds that lay dormant under the surface to a new environment and they will grow right back.
Go read labels and chose your weapon by pre emerge or post emerge products. and don't throw away your weed pulling gloves.

Yes and No Think about it. Farmers spray weed killer on there fields before and after the till the soil. I would wait approximately 1 week to ten days before you plant. The spraying could be done in the early spring therefore giving you plenty of time to plant your garden.....Good Luck

You won't be able to plant there for at least 6 to 12 months, depending on the type of weed killer you used, as the weed killer takes that long to completely evaporate.
Hang on in there!!

If your using weed control it's safe to plant appox., 10 days after an application, If your using a vegatation control such as ROUNDUP, the newer version of this product allows your to plant with in 48 hours

Depends on the weedkiller, I'd ask them in the garden centre which is the best to use for clearing a flower bed, some weedkillers last longer.

no I don't think it's true. You would have to use something pretty deadly and not approved by the gov't if that's the case. Most killers say 24-48 hours before planting

It depends on the weedkiller used - some last longer than others. Check the container before you use it.

Herbicides can be selective and non selective, depend what you're targeting. The residual effect isn't twelve months though, more like one month or less if it rains a bit.

I've never heard of that but it sounds feasible
