Border infested with wild garlic - what to do?
We are redesigning a large coastal garden and will be relaying the lawn and renovating the borders. The problem is that the borders are full of wild garlic and we need to get the place clear of it before we replant. Many of the shrubs will stay where they are so we can't just scrape off the top 300mm of contaminated soil. The area is too large to hand dig. Should we spray? And with what product bearing in mind the need to replant within a couple of weeks.
Any advice?

Hi Janine
Had a client with a similar problem. Wrote to RHS who advised treating it like bluebells that take over - i.e: spray with glyphosate when in leaf, and continue to spray regularly - do NOT allow the plants to flower as they spread as easily by seed as by bulb. To be honest, this worked to a certain extent, but we still had it popping up for the next few years, which I dug up in clumps as they appeared. The Roundup cleared 75 - 80% tho. Best of luck cos I know it's a pig of a plant

Not sure when this work is to be done, but glysophate does not work when it is cold.
We have found that digging up the bulbs is by far the best way of dealing with them,
