Can my idea kill weeds for good?

As we know you spray a weed and the top dies and then it's back. But for those of you that have pulled a weed you will notice it looks a lot like a vain with fluid inside.

What about getting a needle and injecting weed killer in to that vain? Surly it would travel around the weed and lil it at a cellular level?

Is this worth trying?

Thanks

That is just what modern weed killers do do! The words (on the tin) "Systemic weedkiller" may give the game away. The killer juice courses through the plants system and kills it totally, or so the adverts would have us believe. Cheers, Tony.

 

Any glyphosate based weedkiller should do the job, but I find Round Up best.

It won't get rid of weeds once and for all though. There'll be gazillions of seeds in the soil, and glyphosate doesn't touch seeds. It does at least tackle the tougher, established weeds, then the good old fashioned hoe should be enough to keep the seedlings under control.

 

I believe that's how the Environment Agency is dealing with Japanese knotweed; by injecting directly into the stem. It seems the results are encouraging, although it still takes time.
