Dead Head Alliums?

Should I remove the heads of alliums when they have flowered or just leave them?

I want to make sure I have another good display next year.

Thanks.

    I prefer to leave them - they look fabulous frosted in the winter - I've never noticed it affect their flowering.  I do give them a dose of  Fish, Blood and Bone after flowering and make sure it gets well watered in.image

    I agree with Dove, just leave them be. If you're lucky & live in a drier part of the country, or we get a really dry summer, the skeletal seed heads do look wonderful.

    Living in the NWest, not known for being dry, although we've have 2 weeks without rain...., I pick them & use as a dried flower arrangement. Sometimes I spray them with gold/silver paint for using as a Christmas decoration, but only if I have a really good dried seed head. J.

    It may be that the birds like them too.

    And you often get self sown seedlings all over the place too.

    Interesting point about leaving the seed heads. On some bulbs, Tulips, Narcissus for example, removing the dead flower helps the bulb keep its strength for next season, but with Alliums, it is already too late. They flower after the leaves have done their job and begun to die. In fact the flower stem is almost disconnected from the bulb altogether,

    it depends on what type of soil u have and how big yr garden is. if they like yr soil, then u will get loads of seedlings like grass seedlings and they can take over and swamp the spring display so if u have a small town garden, then its a bit of a nuisance and deadheading will be a better option.

    Hence why garlic and elephant garlic going to seed is never a problem for me.. I look at it as free flowers, and no nasty effects on the crop, bees love garlic flowers too.

    Thx for the advice - I won't deadhead my first planting of alliums.  

    Any alternative to fish blood and bone though?  My dogs like it which is not good!
