Getting rid of Borage

Borage is as bad as mint for spreading and taking over the garden. Digging up all the roots would do the job,but not an easy solution if its taken over.You need to get those roots so something systemic like RoundUp is a good weedkiller,sprayed when the plants are growing well it would be taken down.Just need a lot of care about surrounding plants that you want to keep.

Yes, I would also go with RoundUp, use a large piece of Cardboard as a sheild for other plants in close proximity.

The other way of protecting plants in the area when spraying round up is to cut the bottom out of a large plastic plant pot and spray through it, the idea is that the mist only goes where you want it to go and not on valued plants

Thankyou for the replies to my queston. I am going to have another go at digging it up and applying some Round Up to the plants growing out of the path.

In France borage is used as a green manure - dug back in, but before it (prolifically) self seeds and it's also good on the compost.
