Heucheras.A quick question

Yes, I have Washerwoman.
After my sis-IL recommended them for all-year-round cover and colour I started to collect them . Some were in pots, some in the ground and I was surprised to find some of the ones in the pots just lifted from the roots! One or two in the garden beds seemed to have survived (the ordinary ones).

I think it is due to vine weevil although I never saw evidence of the little creatures.
I got rid of the damaged ones and sterilised the pots.

They won't grow in our garden either. We've tried different colours but only the green one is doing okay. No idea why, whether it's the soil or being in Northumberland, so sorry, no advice from us.

Washerwoman the same thing happened with a purple one I bought from Waitrose - the crown of the plant completely detached from the roots.
But there were signs of life in the form of tiny rootlets so I split the thing into about 5 pieces, some I put straight back into the garden & some I put into pots.
All are now thriving so I ended up with 5 plants for the price of 1.

Same here, one blew out of a garden pot completely on a windy day and lay like a jellyfish on the path.Repotted it and it happened again. Planted it in the ground, and it withered away.It was a marmalade one.Out of three now in the garden, only the green one is any good, won’t bother with any more in future.

That's interesting. So it's not just me !Will find an alternative for any others that fall apart.I reckon garden centres must be making a fortune from them.The newer rusty red colours really catch the eye initially but aren't worth it it seems.

The dark burgundy ones seems to be OK in my garden beds but the marmalade one was a victim of whatever it was. SisIL suggested vine weevil and she is quite a gardening expert.

I agree with the vine weevil theory. I have a marmalade coloured heuchera called, 'Ginger Ale'. I'll be keeping an eye on it although there is no evidence of vine weevil infestation in my garden.

Fingers crossed.

You can buy stuff from the garden centre to water affected plants with. It is expensive but worth it if you have say large camelia's or other plants that in themselves would be expensive to replace.

We have had threads on vine weevil over the years and my bet would be vine weevil is a distinct possible cause as heucheras are prone to them but usually in pots. I have had infestations of vine weevil over many years and cannot eliminate the little b----s.

Good luck if it is

I found nematodes, bought from the internet, were a good way of knocking back vine weevils. My first treatment lasted about ten years before I needed to repeat this year.

I've had no success with them in my fairly large sandy garden and have now given up on them. One or two survived the spring/summer but then lost in winter.

No problem with them until we moved here where they just don't thrive. Soil is much the same but obviously not . One lasted just a year, the other two. No vine weevils as far as I know but maybe I just haven't spotted them.

I love them but I only have the darker variety that survives here it's snails that feast on them and on my hot poker, it's so frustrating..

Sounds like vine weevil to me too. I have had this problem with Fuchsia & Begonias in the past & just had to buy the chemical stuff to use which is now banned. Last year when I had overwintered my Begonia's in a shed, found the nasty little grubs when I was repotting so had to throw all the corms away. I had been overwintering them for several years with great success so was a bit cross. I asked on here about nematodes & had several positive responses so bought some from Amazon as I did not want to lose all my Fuchsia's as well as I have many in pots. Used as directed I am hoping this has solved the problem for a while a least.

One of the big show Heuchera companies "Plantagogo" is about 5 miles from where I live in south Cheshire and has open days .
One of the owners suggests getting rid of vine weevils by cleaning out the roots by using cocktail sticks to stab the grubs and dispose of them.
Or use vine weevil nematodes.

I lost a marmalade one, thought it was something I had caused to kill it. Such a shame as it was my favourite of all heucheras but I am willing to try another one this year so, thank you for the tips re vine weevil.

The purple and green are thriving which were alongside the marmalade so really no idea why it died.

Huechera grubs happily chomp the roots of this plant leaving the top of the plant to topple over and die.
Do look up the varieties.
Some are much more prone to being eaten
