Help -Weed problem

Hi - I was hoping someone could help me. I installed a patio area a few years back with a chipped border. And every spring there a certain type of weed that comes through. It’s really tough to get rid of and tend to die off around autumn. My question is does anyone know the names of this, and how to treat it to prevent it coming back. I’ve uploaded picture with it shooting and the end result. Much appreciated, thanks Andrew

 

Hi Andrew, the first one I dont really know but may be horsetail, at this stage I think this is where they release spores? but have had a couple of them grow between pavior and flags too, I basically use weedkiller on them, but yes they come back.

The second picture i am pretty sure is Horsetail/Marestail, in fact I was on a week or so ago asking about them as I had young ones sprouting and wasn't 100% per cent if they were horsetail

Looking further in to the horsetail treatment, Glyosphate seems to be the preferred treatment, I used Resolva extra strong as it was all I could get and it worked (I can usually get Glyoshpate professional stuff, but lock-down has snookered me for that at the moment)

But by all accounts it's not a case of sticking on weedkiller and thats it, you need to try and keep killing as they come through and seemingly it can take up to 3 to 4 year to get bad infestations under control?

I'm pretty new to this, but I'm sure some of the more experienced and knowledgible folk will update to confirm or correct my info if wrong?

PS: put in a search on how to kill horsetail weeds and it will take you to plenty of websites ((being new to forum I cant post external links)
