My nemesis - Snowberry

So 4 years we bought a house that the garden hasn't been touched for 10 years. Needless to say the snowberry was rampant. Stupidly I chopped it down and I swear I could hear it laughing evilly .Within a week or two it had grown like nothing I had seen before. I've had the digger in and it's got rid of most of it but there's some deep thick roots which I've chopped as much as I can with the root slayer. My question (s) is if I put a weed membrane down and lay lawn will it still come through? (more in hope than expectation for this quick fix) Or which I've read on a few forums to put thick black plastic down, which I guess I will have to have top soil then lay lawn. Any other ideas (dont want to use weed killer or nothing too strenuous I'm getting too old!!

 

Glyphosate?

 

Sorry my fault, the ground is organic so l didn't want to use weed killer

 

Digging presumably is your only option then I would think.
Although its not a plant I have ever dealt with.

 

If by snowberry you mean symphoricarpus, it doesn't give up if you mow it, it just relocates itself to a more inaccessible area of the garden.
Sometimes the only option for a pernicious weed or shrub, is a chemical intervention. if you don't like using stuff like that for whatever reason, then it's constant digging to remove it

 

We bought in 1978 and still have it but thankfully we have been able to reduce it by cutting right back as far as we can. It does appear in the road side hedge but as this is also cut back it is kept back. We don't use chemicals.

 

Ideally lawned, yes - I just wanted to know the best way to stop the (explicit swear word ) snowberry attacking the whole garden again.
I know it needs to be dug out but being a senior its too much for me - some of the roots the digger got out were around 5cm thick. Like I said the garden had been left for a very long time.

 

Look on the bright side:

1. It is one of the food plants for death’s head hawk moth.

2. It was introduced to Britain from the USA to act as game cover. Invite a friend to make the most of the cover and try out some new games.

 

It is an absolute swine as I know from personal experience.
I have it at the back of a flower bed and just keep cutting it back.

If you don't want to dig or use Glysophate, I think the black plastic/membrane is your only option. From what I've read online, you need to make sure not even the tiniest chink of light can get through, and it may take up to a year,

 

Ha that really made me laugh - thank you

Ha - that certainly make me laugh
