Distorted leaves on Cyclamen persicum var. autumnale -

Unfortunately most of the leaves of my one and only plant of the autumn flowering variety started like the smaller one shown here. Some of them grow to a normal size but a little bit later all wilt.
Although I never came along them - I guess the cyclamen mite caused the problem.
I would be glad if there is a grower of cyclamen who could tell me whether I'm right or if there could be another reason for this phenomenon.

Kris very nice congratulation and well done.
Is the rock garden protected from above by a tree or similar or do the cyclamen get rain on-top of them directly?


Joakim

Thanks Joakim

We have a very sunny rockgarden.There are no trees .I have different ciliciums on different spots in the rockgarden.They not like to much wet I suppose but between the rocks and crevices they get no to much.
Most of them get no protection against to much rain  (we get in winter a lot of rain most of the years).
The result is that most of them are not so pretty in the (late) autumn/winter.They survive and  flower well but the leaves never looks very good under that condition in some years.So now I protect the ones with the best leaves......against to much rain from above........
Looks very nice Kris !
I didn't think C. cilicium could survide outside here !

You must try this one Luc.If they thrive in our area ,I suppose they wil grow also in your part of the country as you are living more in the direction of the coast ?

Today by controll one pot os my Cyclamen I found one of this beasties which kills by night my Cyclamen leaves and flowers .....

In Germany I think we call this Eulenraupen .....maybe Anthony can help us with the correct name  ???

Have other members this pest too ?

Hans - I have had this pest. I call them 'cutworms' but I am not sure if this is correct. They seem to hide in the soil by day & emerge at night. I think they are the caterpillars of winter moths but Anthony will know for certain.

I am having problems with this caterpillar at the moment too,it is an Angle Shades Moth (Phlogophora meticulosa) caterpillar and I usually get an infestation about this time of year. I find that looking for them at night with a torch is usually effective, carefully look on the underside of the leaf because they drop off at the slightest movement, they usually hide in grit during the day. The species worst affected seem to be Cyclamen graecum and C. persicum.

Hans,
Don't know the latin name but ' Eulenraupe ' is correct - cutworm also. If you hesitate to use an insecticide start a search in the neighbourhood of the damaged plant (don't forget the soil) and catch/kill the little beasty.


Distorted leaves on Cyclamen persicum var. autumnale -

Unfortunately most of the leaves of my one and only plant of the autumn flowering variety started like the smaller one shown here. Some of them grow to a normal size but a little bit later all wilt.

By the way - no solution for my problem?

Hi ,

thank you to all !
It seems I'm not alone with this problem .

I use the same methode like Melvyn ...by nigth with a torch and a long pinzette .....

I dont believe that any insecticides work ....

Gerd : I think you have to use a Akarcid like Kiron or anything .....

Thank you to all
Hans

In my experience insecticides do not work once the beasts reach this size. When I had a bad infestation some years ago I  captured some of these pests & put them in plastic boxes with various insecticides - both powder & liquid. They were unaffected.

I found this cyclamen at my favourite florist yesterday.  A fascinating form which, assumedly, the flowers remain only partially opened due to the enlarged calyx-like growth.  I rather like the umbrellas of deep cyclamen purple.  I take it this is a C. persicum selection.

Sorry for the lousy foto.  It is so overcast out, a good shot is impossible.  Manno, I hate dark, wet, cold weather!

Hans, I'm quite sure pyrethroides do - please google for Karate Zeon (Lambda-Cyhalotrin). It is effective even during colder weather.
Another question is - is it worth the trouble to spray?

Thank's for the hint concerning the Cyclamen - I treated with an acaricide!

Gerd ,

I have looked today on a database for plant protection :
all this insecticides against Eulenraupen are not allowed for private gardeners .

I agree with you ...it is not worth the trouble !
Yesterday I have conrolled all my pots of Cyclamen .....I saw no other cutworms ( but I suppose there are any )

I think the caterpillar above is that of a yellow under wing. The caterpillar sleeps by day in pot contents
