Neutralising effect of lime on Roundup on beds?
My neighbour's 'gardener', I use the term loosely, persistently uses Roundup on her beds. No wonder nothing grows there. Now he has just strimmed the David Austin rose bushes I bought her in memory of her late mother, destroying lots of buds that were just coming and leaving the plants with ragged stems. My neighbour is furious and is going to sack him. I would like to plant lots of spring bulbs for her as a surprise, I've read that garden lime can neutralise the effect of Roundup. I also plan to buy some compost to improve the beds - do you think that will be enough for the bulbs and anything else I might plant to thrive? Thank you.

According to Scotts, the manufacturer of Roundup (glyphosate) weed killer, its safe to plant ornamental flowers, shrubs, and trees the next day; and they say you can plant grasses and edible plants and trees after three days.
As weed killers go, glyphosate is considered relatively safe, because of how quickly it breaks down. However, when using a glyphosate weed killer such as Roundup, I’d always give it a few days to do its job and be gone before you start digging.
I wouldn't personally plant any annuals or perennials for a week or so afterwards but bulbs will be fine.
@Helen Bang - hopefully, your neighbour's roses will recover too if she gets rid of him. Most of them are pretty robust. The problem with many 'gardeners' nowadays, is that they aren't gardeners.
