Hi NiNi,

the symptoms you just described could be caused by a fungus.
There are several reports of a fungus called Colleotrichum
which has caused simular damages in collection all over germany.
Colleotrichum is very hard to fight and cannot be cured by
any known kind of fungicide.
All infected plants need to be removed from the collection.
As I said, if it is this one !!
Fungi are very hard to identify, so if it is getting worse, you should contact
your local pest control office or agriculture ministry.
Maybe they can help you to name the enemy.

Please keep in mind: This is just my suspicion.

Greetings and good luck for 2009 !!
Timm

Thanks for your answer
Can I try to take preventive action to apply to the still-in-health-plant?
You talk about a fungus that caused damages in germany and I bougth all my plants there http://www.tillandsia-shop.de/, in germany too. If it is really a fugus, can it contaminate a plant without immediately breaks out? because I would like to keep alive my others plants which I all buy there...

I am a little scarry about your answer but thank's for it, its help me. Thank you very much.

just a small litlle question, absolutely not about the fungus :
I don't like mounting at all (esthetically and handily) but all the site and the books I read always spoke about. Do you think that mounting is better for the plant growing?

According to www.colletotrichum.org garlic powder can be used to control it. But check that it has no salt or added ingredance in the one you buy. Experiement first. I have uses fungicide powder for collar rot and plants have recovered. You can look up on the above site.

thank you mod, I was precisely hesitating between watering by spraying or by under watering.

bristow48 :arrow: How can I use garlic powder? How much must I blend in a litre ?

Well, most folks I know prefer mounting because they find it esthetically
If you don't mount them, how do you cultivate them ??????
In pots ????
NiNi hat geschrieben:Do you think that mounting is better for the plant growing?

Its a simple as that: That's the way grow in their habitat.
Some species prefer a little soil around their feet though,
but the species you mentioned above should be all mounted.

Greetings Timm

In its powder form, dust it on, using a small paint brush. On a test plant if works, use it on the others. Ensure it is pure with no add salt look on the packet. If it dozen work as you french would say k sara sara.

Hi NiNi,

well if you keep your Tillandsias like that, it is no surprise to me that you are
having trouble with fungi. In my opinion it is way too wet.
Keeping them on a glas filled with water causes constant humidity around
the base of the plants. Those Tillandsias don't need that much water.
They need watering and should soon dry afterwards.
To get you an idea: I have mine mounted on a piece of wood and they get
water once a week during wintertime !! I have some grayish species like
lorenziana or purpurea for testiing in a cooler greenhouse
at temperature around 10°C.
They have not been watered since October 1st 2008 and look just fine.

So you might give this a thought.

Greetings, Timm
