Hi I adore Heucheras and have a few, I was thinking of purchasing more but a couple of my prized plants have been ravaged by the vine weevil larvae, I have salvaged parts of the plants but it won’t be long before they fall prey to the bugs again, I was reading nematodes a good option?
Any other tips or clues how to get rid of them ?
Kind Regards Linda
Met 52 isn’t as good as we all thought! (That needs changing really )
So here is our recommendation now
Vine weevil control
This time of year all the Vine weevil are hatching and looking for somewhere to live and feed.
The adults love a leathery leaf so tend to head towards viburnum, rhodo, azaleas acuba, acers, etc to feed in the evening at dusk.
You will know they are there because the leaves will have notches on them
So in the day if you go out to the eaten nibbled trees and pop a couple of umbrellas up side down.
Then go out at dusk and shake the bush /tree see if they will drop off into your upturned umbrella
If they do take them back to the patio tip them out and have a lot to dance on them …remember they are not dead until they crunch!
Repeat this throughout the summer.
If the neighbours look at you funny invite them to do the same in their garden …the more the merrier!
Then come August and September get nematodes (online and garden centres) and water that on them.
In spring it’s always a good idea to keep a close eye open for any loosening of the crown (leaves) if they feel very loose dig them out and wash off the roots looking for the white crowns.
Hope this helps
