none if its growing in your garden,you can let it grow if you like-if its growing on a farm then allowing it to spread is a breach of cross compliance. if its growing within a meter of a watercourse you need pa6aw and permission from environment agency to spray it.

Ok thanks

What about if I was offering the service?

just keep all your records in order as to what you've sprayed,with what and when and you should be ok i'd say. obviously the spray you use has to be passed by maff etc. as being ok to use

I would be carefull when you speak to clients about treating knotweed that they may think spraying may get rid of of it completely depending what chemical you use.

I treat a fair few areas with roundup and I explain to the client it keeps it at bay but will not eradicate it completely.we spray once a year it gets knocked back but it comes back the following year.

There is something that treats knotweed completely but I was told you cant replant anything for 2 years.

If you are doing knotweed with roundup would be worth letting client know this as they may think once treated that's it and when it comes back they will be on the phone to you.

Round up can be effective but you need to treat 3 times a year for 2 or 3 years, clearing the dead winter canes and spraying the new growth early in the season is pretty effective, or using stem injection if spraying isn't a viable option.

look at himalayan balsam aswell- causing big problems in a lot of places-you might get contracts with councils or the environment agency to get rid of it
