A young Herrenhäuser Gärten plant
Picture of Virus Herrenhäuser Gärten
Monika I think we all have some virused plants here in USA because so many growers are propagating virused stock and not tissue culturing. So do you cull all virused plants even if they don't contort or deform in their growth habits?
Monika and Eclipse, is the Pressel book wrong when it says that virused plants cannot be rooted? and what is different about polyvirus?
I cull all plants that show signs of Virus infection.
I had all plants checked in a federal labratory several years ago and almost all were infected. I talked about tissue culture with my Dr. friend, I really did consider this type of cultivation. Its to expensive. To get my whole stock free of Virus it will cost about € 50.000 plus the cost each year for renting a place at the labratory plus the costs for raising the young plants. A isolated greenhouse is needed to grow them until they are ready to sell. I had considered to throw all plants away and repeat the crosses to get free stock through seedlings. But the new stock must be kept in an isolated greenhouse. Otherwise they will be quick reinfected again. Be truthful, that is a number too large for me. I am a little breeder, nuts about Brugmansias and never earned a Dime with them. My little nursery is paying the costs for running my hobby.
We have many things in common Kyle; even being not to good buissness people. I gave over many years young plants away for nothing. Every year the same people came asking about plants until I found out, that they considered it to be much cheaper to get every spring young plants for nothing instead overwintering. Thats when my husband got angry and from then on, I asked a small price for good sized plants.
And got rid of these people.
Thanks Monika for posting pictures of virus infection in Brugs. They was very informative in themselves and I studied them to compare with the diseases I know here from Sorø.
I have another garden, where I sometimes move apparently infected plants to, in order to see, how they behave. The yellow x flava (posted elsewhere here) have been there three times, but luckily it turned out to be nutrition deficit. The leaves was in one instance mottled, but very different from the pictures you posted here or have in your book. In all instances, where I doubted, what happened to the x flava, it was grown in greenhouse mid summer and in high level of air humidity and sandy soil. It helped to add lot of magnesium and a little mangan. btw. the calyxes on this hybrid has to be forced open by hand, if not the flowers should be trapped inthere and (rarely) come out cribbled.
Monika - would you take a look at these pictures I posted a while back http://davesgarden.com/showthread/177887.html

I was all fired up to trash these plants and then I felt I was being rather paranoid. What do you think? They're not the best photos but I hope you can see what I'm talking about.
I feel i could have a virus on HG, used the schultz transplant with b vitamins and rooting solution. the hg froze back, sat inside a few weeks and i watered. when i got it outside it was very pale, now it looks kinda funny. but the leaves coming back on my confederate rose look kinda like that, too. will fertilize in a few days and wait and see.
Culling all plants with virus's is a very good way to cull as well...Just pulling this back up as I think its a good idea and wanted to draw some attention to this. I think fast growing early blooming is a definite plus...but the real underlying issue is hardiness and fertility.
