Do my grape hyacinths have to go?

BerkleyBerkley Posts: 331
I have a large collection of sempervivum in my rockery, which give me a great deal of pleasure. But they are now completely covered by grape hyacinths. These will disappear very soon of course - but are they harming the houseleeks - and if so, should I get rid of them? Presumably I'd have to dig everything out?

    I wouldn't think they would compete - the muscari will die back down and lay dormant beneath the soil til next spring.  Sounds like a good combination to me image

    The Stone Age didn’t end because they ran out of stones ......

    Forgive my ignorance, but how will they spoil the houseleeks?  Aren't they just like daffodils that you can plant things on top of for later in the season??

    I'm with Verdun. I agree they're an invasive weed. Pretty enough, but so are the flowers of bindweed, ditto Celendine are pretty in their way too, but weeds nonetheless.

    muscari will multiply quite beyond reason but if you rip the foliage off as soon as they finish blooming it slows them down considerably-i wouldnt be without them-and they make excellent mulch-the white muscari have good manners and are wonderfully pretty

    I read somewhere the other that the gardener gives them a hair cut, .just remove some of the leaves until you think its tidy.  The bulbs will still come up next year.

    They do get a bit out of control and you can move them to other places otherwise they will take over.

    I like both but I wouldn't let the Muscari in with my Sempervivums............they won't actually kill them but they will bulk up and take over.  Also as the Muscari leaves die down they will drape themselves over the Semps............to have a nice display of your Semps, you will then need to pull off all the rotting Muscari leaves.  Apart from anything else, the 2 species like different conditionsimage

    I'd been thinking of removing some large clumps of grape hyacinths in a new border I made last autumn.  So I took them out and planted the area up with some free bulbs I got, including some called muscari.

    I have to admit I laughed when I saw them start flowering last week.  Another lesson learnt.
