How do I get rid of  rampant alstroemeria in flowerbed? Dug deep in spring and filled bin with tubers...several weeks later they're back! Several prized plants beside them so wary of spraying weedkiller. Help!!

    My daughter had the same problem, the one with the dark leaves and deep orange flowers. 
    All you can do is keep digging it out.
    Here, in my garden it just stays where I put it, I’d love it to spread around.

    I have just spent an hour pulling out the same orange alstroemeria flowers. They were well behaved for years, staying where I put them. This year they have taken over! They are easy to pull out - and I will try to dig them out in the autumn.

    Good luck digging them out...I went down 2 spade depths and they still recovered!!

    And the info says the roots are fragile  :/

    I’m so envious! I love alstroemerias, but had assumed they were delicate and hard to grow. I have a suitable bed they could take over, I’ll get some next trip to the garden centre.

    Any piece of those ones left in the ground will regrow. 
    If you can't dig them out, you'll have to use a weedkiller, carefully applied. It's perfectly possible to do that. Do it on a still day and apply to the foliage from close up. It's then unlikely to affect other plants nearby. Resolva [the 24 hour one] is better than any other as it works very quickly. You can always enclose the foliage in a plastic bag to keep them separate too - in the same way as doing bindweed.

    I had it in a previous garden but it was useful as the rabbits didn't touch it.

    I hope mine spreads,  daughter gave me roots which I planted around the garden,  although they’ve just started to flower, they haven’t spread a bit, still the same size plant that I put in .
    I don’t think I have the climate for them,  usually if @Fairygirl can grow it, so can I.

    Thank you Fairygirl, I'll try that method with weedkiller. Don't like using it but they're inhibiting other plants around the bed.

    We had it in a previous garden @Lyn, but it was in a pair of beds , one either side of the front door, and enclosed by a gravel driveway, so it could only go so far. I did get it spreading into the gravel drive a bit though, but it wasn't a massive problem.

    I think I was just in time digging mine out, it's now in a pot. They were beginning to spread. I'm keeping an eagle's eye on the spot to check if anything pops up. Initially I was elated with the Alstroemerias (these are a fairly red variety) but I'm not so sure anymore ... it's seems almost artificial in it's machine-like production of flowers that last for ages; it becomes a bit sameish. Maybe it will work well with the flexibility that a pot gives.
