Weeding a Gravel back garden

[theheadlander]

I purchased a house with a large graveled back garden a few years ago. I have tried to keep the weeds at bay but now they are getting out of control.

There is grass and Japanese knot weed now trying to take over. I have been using a number of known brands of weed killer but nothing seems to be working.

If you are sure its knotweed then be wary and get it under control asap.

There are a number of dedicated killers for it which are most effective but are all licensed pesticides so not available to the general public. If you want to get someone in they will be able to treat it so that you will absolutely eradicate it but it will be expensive.

Generally to keep on top of it make clean cuts with sharp secateurs about a foot up from the ground and burn the cut stems. Then get some sbk brushkiller or other woody specific weedkiller and pour a little down the remaining stems.

It will take several seasons to properly eradicate and if its in an inconspicuous area ongoing management is realistically much easier.
