Cyclamen Problems

Pests and diseases are afflicting our Cyclamens and consequently me.
First, de disease, which is only supposed yet.

Two or three years ago I got two Cyclamen graecum tubers from the UK. Somebody wanted to get rid of his Cyclamens, which were down at the heel.  I thought I may try two graecums. I potted them up and admired their beautiful leaves every autumn since then, namely no flowers yet.
This picture was taken in October 2009:

This year they started to grow rather late and slowly, as I showed in an earlier post, despite of the watering. And finally they pushed some ugly, distorted leaves:




I decided to get out the tubers and look into the compost maybe I could find the reason. But the tubers were healthy, hard, the compost had a good drainage and was just moist, and also the roots seemed to be OK, though they have not grown too much during these years.


Especially this one looks rather odd with so much dead leaves on the top of the tuber, and scarce roots:


I showed the pictures to a friend of mine, he suggested to make also a section of the root to see if there is a fungal disease. It seems like healthy:


I found no vine weevil larvae, which can eat all the tuber, as you can see here.
So, we thought it could be a virus infection. I potted the up again in fresh compost with more sharp sand, and give them another year to live. Will see next year if I should discard them or not. Whatever happens, I separate them from other plants.


The other trouble is the caterpillar(s) of some moth, which have disfigured my cyclamen seedlings:









Yesterday I found a culprit. I put it in a pillbox for my friend, who will grow it to see which species is it exactly. In half an hour it ate a large part of a florist's Cyclamen leaf:


Here it is decked out in all its finery:


I don't know if there are any more, I would like very much to find them before they gobble up all my seedlings' foliage...


The following is neither pest, nor disease, just the poor light. This Cyclamen persicum cultivar is becoming a weeping plant, and I must say I quite like it :)



Finally the good news.
One of those chewed seedlings, a Cyclamen pseudibericum has three buds, predicting the coming spring:

We Must Prepare for the Winter

Sadly.
This autumn was very rainy and cold. The autumn colors are not so wonderful as usual as the leaves suffer from all kind of awful fungal diseases because of the much cold rain. Our lime tree has lost all his foliage by now, which in "normal" years had happened only by the end of October.
I don't want the alpines to be wet any more, so we put the cover on the troughs in the garden. We cooked up something new this year, my husband made it and I believe him that it is stabile and okay.



At last the leaves of Cyclamen graecum are showing up. I've got these corms two years ago, in rather bad condition though with some healthy roots. But until now I did not manage to convince them to flower. I think these are only leaves again:
