Vine weevil damage on plants
Wednesday, August 13th, 2008I have discovered some vine weevil damage to plants in my front garden. The vine weevil is a grey beetle that damages cultivated plants in its adult and larval stages. The adults eat notches into the edges of plant leaves and seem to prefer plants with crunchy leaves like shrubs, although I have found damage to Heuchera as well as Epimedium in my own garden. Their larvae lurk below the soil and concentrate on eating the roots of plants preferring Sedum, Fuschia and Heuchera. Plants in pots seem especially popular with these pests.
If you think you may have vine weevil damage you could try using one of the organic methods of control that work by introducing a predator nematode nto the soil that attack the larvae and kill them.
The soil needs to be warm and preferably wet because the microscopic swim through the water in the soil to reach the weevil larvae. You can often buy the nematodes from large garden centres or over the internet and simply mix it in a bucket of water and apply it using a watering can to the affected areas and pots.
I have been using them for the last few years and although I still find a few weevils I see far less damage than I did before I began treating for them. I prefer using the nematodes rather than chemicals because they don’t target any other insects that could be beneficial.
