Vile weevil is a problem throughout the country. If you have difficulty identifying it, this blog by 'Scottish' who lives in the Edinburgh area should help dispel any anxiety. It is also a timely warning that the adults are busy laying eggs and the grubs are doing their worst below ground.

Don't be fooled by appearances!

Other than the obvious colour difference (and not counting the Aquilegia seedling in the second picture) you could be forgiven for thinking that both these pictures were of a healthy plant – right?



Heuchera Caramel July 2013



Heuchera Caramel October 2013

Well, so was I!! Until earlier today that is! I have walked by this scene countless time over the past few weeks. In fact, I’ve even been praising myself on how great this Heuchera has been performing this year.
Something just didn’t look right – it seemed to lack a bit of lustre, if you know what I mean. I bent down to feel the soil underneath perhaps it needs a water.
As I slipped my hand underneath – it immediately became apparent what the problem was…..



If we look a bit closer – the culprits!



Before dealing with the plant, I removed a fair bit of soil/compost from the ground – only 2 more larvae were found



I took the plant indoors – the object was to split the plant up and completely wash through what was left – removing any more I found



I should add at this point that by dividing up and washing through completely, making sure you get into every little bit – you will do the plant no harm. As I’m sure others will agree.
If you would like any more information on the Vine Weevil and her larvae – here’s a link to the RHS page which is full of information. http://apps.rhs.org.uk/advicesearch/AtoZ.aspx#v
Here she is……The adult



…..here she was!



Torn apart and washed out – ready for repotting



From the one plant, I was left with 10 divisions. They will/should root easily enough. I’ve left some of the leaves on until they start regrowing.
In my experience, I’ve found I had greater success with dividing heuchera and planting them directly into the soil but since I had so many I split what I had 50/50.

5 potted up



the other 5 planted in shady spots around the garden. Where they can be left to do their own thing until spring.




The larvae didn’t go to waste either….

Popped into Mrs Robin’s feeder



I had no sooner turned my back and they were gone – I do hope she enjoyed them.



When all was finished I went round all the Heuchera growing in the garden and gave each one of them a little tug – all are firmly rooted in the ground and touch wood, they stay that way!

An update to this info is
1. that you can pop the grubs in bleach to kill them but that will not work with the adults.
2. There are commercial products available for getting rid of vine weevil but they work best in containers rather than in the open ground.
3. Some may only work at certain soil temperatures. Always read the information leaflets that come in packs.
4. some may not be suitable for use on succulent plants like Sedums.
5. The eggs are hard to spot. If you find grubs in a pot treat the soil with boiling water to kill the eggs. 
6. If you must keep the soil do not put it in your compost bin. 
7. Vine weevil beetles eat irregular holes in leaves of plants during the Spring and Summer. If you see the holes go round in the evening and use an open umbrella to catch beetles as they drop to the ground to escape detection when you gently shake the affected plant. Squash any you find. They are quite slow moving. 
8. You are more likely to see the vine weevil grubs in the Autumn and Winter when the eggs hatch and they munch their way through your plant roots before emerging as beetles in Spring.
