Weed killing gel.

In my main flower bed I'm having a bit of a weed problem and every time I pull one it pops its head back out a week later.
Does anyone know if it's safe to use a gel weed killer to just touch the weed leaves or will the chemicals contaminate the soil and harm my flowers?

 

Hi ya, I & others on here have tried the roundupgel, it's not the greatest product on earth but if you are very persistant you should get some results

 

The gel type stuff is expensive. You could save yourself some money by getting a small sponge (a make up sponge is good), a thick pair of rubber gloves and dab the weedkiller on with the sponge (or paint on with a small paint brush)

 

Are they perennial weeds or annual, if the latter they will disappear of their own accord soon, both will reappear in Spring, that`s when I would treat them, removing any seed heads now if possible. Any weedkiller needs applying in a dry spell for the plant to absorb to its roots, not likely now the weather has broken for Autumn.

 

With the domestic stuff you need a nice dry spell for the chemical to intake, pro chemicals need as little as an hour depending on the product used. What you need is an active growing plant for best performance and there is a residue factor on products like roundup all be it a short time scale but worth noting.
Small weeds in borders if treated can be painted on or sprayed using a hood. This time of year the performance will be much slower on most plants targeted.

 

Thank you for all the replies you've all given me lots to think about
