I thought I would post this about what happens to heuchera when weevils eat the roots.

I was looking over the garden today and saw that this heuchera was a little wilted. I new it was not a lack of water.
I slight tug on the heuchera and it comes up with no roots

This came out a bit blurry but you can see no roots.

This a weevil. They eat the roots and boar up the fleshy stems.

Not any more. Squish!!! there was more than one.

Not all is lost. I was able to get 4 clean cuttings from the heuchera. With any luck I will have 4.

Don't throw the hechera out, you may be able to save them.

I don't know anything. I have to have my glasses on and really look at the stems to find the weevil. Sometimes cutting the stem will show them. Chris, it happens but if the cuttings take I will have 3 to share. Big Grin Hilarious!

Hi Bob - Yesterday I saw root weevil larvae in the soil when I moved Redstone Falls and dug some others to check and found many. I need to research what type of nematodes and when to apply. It's getting frustrating as there is always thrips and aphids to deal with on daylilies, rabbits munching daylily foliage at nose level, and the voles are back. Last year I had to apply milky spore for grubs which ate a portion of the grass. Just never ends.

This is an older post, but here I am... Does anyone know of a treatment for the root weevil larvae other than pulling up the plants? I tried pouring near boiling water over the plant, which I read about, but it didn't seem to work that well. Also, any ideas for treatment for rust short of tearing off all the affected leaves? ( which is almost all of them on some of the plants).

Have you tried a systemic solution? They sell Bayer granules at Lowes that might work if you sprinkle some around the base of plants and water. They are for roses so I would use less per plant. It's worth a try.

Hi Clint, boy, small world! I'm just passing thru, don't know how many forums I can swing long term. Sad

I do have some of the Bayers for my (one) rose bush. I guess it's worth a try. I also read about nematodes - has anyone used those?

Sorry Patty, I don't have any experience with root weevil. But I sure wish you luck in getting rid of them. If you find a solution, please post it here.

I guys. I have found these to products to be affective.
Thumb of 2013-04-07/springcolor/175444

The infuse is for the rust. I started using this last year and I have noticed a big difference this year. Much better. You need to cut all the infected leaves off, then spray with the infuse. I even go as far as removing a bit of the top layer of soil and add new compost.
The other is for the weevils. However most of my heuchera are in pots. Seems to work good. We will see as spring moves forward what happens. If you notice one is wilting its probably weevils. If they are that far, the only thing you can do is what I posted above.
