Hi, would anyone know what this fern/bush is and why it has taken over our front garden?

We trimmed the main plant as it looked like the top branches had died. Within a few days small plants were coming up everywhere and have now taken over the front garden, please help as we need to get our grass back..

 

Looks a bit like Rhus,

It speads like crazy especially once you cut out the main plant.

Think I'd use weedkiller, (glyphosate) if you want to get rid of it permanently.

 

Thanks for all your help, its spreading all over the place. Part of the grass is owned by our council, should i contact them for advise?

 

Thanks again for your help, should i contact my council.

 

In my experience,no, you will make a smallish job huge, just spray it as Pete suggested over a weekend

 

Er, Marley, you will be pleased to know that Rhus typhinus IS Sumach.

 

Hi Marley, no need to delete, we both posted without the knowledge of the others post.
Sumac is the same plant.
Rhus being the Latin name.

jem, I'd not both with the council, just hit it now with the glyphosate, in a month or so it will be too late.
You might need to kill a few remaining shoots next year.

 

Ill take your advise Pete, can you get glyphosate anywhere?

 

Often called "round up" but there are other trade names, the actual chemical is Glyphosate, have a read before buying.
It will kill any grass also, but it has the benefit of becoming in active once it touches the soil.
So there is no harm to the soil and next spring you could reseed the grass area.

 

If you do not want to kill the grass then use a Lawn Weedkiller. Verdone do a good one and it does work on Tree suckers.
