Vine Weevil

I have found vine weevil larvae around root of my Heucher. Can I save by using nematodes now or should I discard it?

    I'm afraid I resorted to chemical means. Nematodes might be  a bit inhibited by the low temperatures at this time of year. Also the grubs will be quite mature and will have done serious damage. Are your plants in pots? If so you can do a drench of Provado. 

    I take it you've picked out the grubs. If there is any root left at all, stick them back in again and hope for the best.

     

  • Thank you plant pauper, i will try Provado, I have picked loads of  grubs out and about half the root remains.  It is in a pot,

    Verd's said everything I was going to say, but I'd agree with Tetley - I think heavier soil is better for preventing attacks.  I definitely have some vine weevils in this garden but my Heucheras seem untouched.

    It's a place where beautiful isn't enough of a word....

    when I repotted my hostas and agapanthus in spring ,, many of them had been severely munched by the little bleeders.

    I've lost a couple of primulas to them as well and the worrying thing about that is that they weren't in pots, they were in open ground

    I think mine are in the ground rather than pots pp. No potted plants have any damage to them but the rhodie at the front door has, and a few other shrubs. The heucheras are all fine, but I'm 'watching this space'... image

    When you use the vine weevil killer in a pot, put the pot in a basin to catch the run -off  and then you can pour it into another pot.
