Killing crocus bulbs

....so we are redoing a garden for the new owners. There is an area about 30' x 80' that was a flower bed. The new owners want it to be a lawn...all fine so far.

I wanted to get it prepared and the turf down nowish, but the ground is so waterlogged i cant get on it to do the prep. However loads of small crocus bulbs have come up. Can I successfully use Roundup on them?, Or am i going to have to dig up every individual bulb....ie hundreds?

Thanks

Adam

  • Why bother doing anything? They'd look lovely in a lawn in the Spring + you should get rid of them for good once you've mown them down on the first grasscut, they'll soon die off anyway so the "problem" should go away.

      because the client is adamant they dont want the bulbs coming through the new grass :(

        just mow them -- it may take a year or two but without leaves left on for long enough the bulbs will run out of energy and die -- poeple that cant handle crocus in grass are a bit weird IMO

    Pretty difficult to kill with a herbicide. glyphosate + sticker adjuvant would work well if you can spray before turf is laid - but best results at the end of the season rather than beginning. Burn down (but no bulb kill) through Finalsan (non-glyphosate) pelaronic acid - again before turf laying.

    Post turfing - mowing, as Dan says, is your only option or digging out -  as crocus are a monocot  -  so not controlled by a selective herbicide!

  • The most successful way to get them out is to use a hand spade and dig at least six inches wider than the bulb and to dig deep enough to get all the roots.

    Weed killers can kill crocuses but but with water levels high it would be more resistant to it.

    Chemical control should only be used as a last resort, as organic approaches are more environmentally friendly.

    I sent the bill for this week's session in, explaining removing these bulbs is going to take many hours. The wife who demanded their removal has been overuled and the husband has said just turf it and she will have to get used to them coming through :)

    • At least sense has prevailed. Not wanting crocus to come through when the garden is at it's worst and the lawn is virtually dormant seemed a strange request.
