Thanks again Ken. Yes the appearance now has become less specific, but earlier on the pattern included mosaics and chlorotic spots more typical of a virus.
Thank you for sharing the information. I’m curious, you mentioned you left the diseased plants for about a month so you could watch the “for science”. Were you not concerned of insects spreading the disease to healthy plants?
Hi Andrea, thanks for your question. Well yes, it is a worry but my experience is that viruses tend to limit themselves to a single variety, so the worst outcome is a loss of all plants of that variety, numbers were small otherwise yes I would have taken much speedier action. I hope yours are and remain virus free.
A brilliant and informative episode clearly explained. I've learnt now to 'quarantine' my newly bought plants in the first year in a separate bed. It is so common as you say unfortunately.
Thank you. We are supposed to get a frost here in New York and I’m going to check my plants for virus before the leaves turn brown! That is sad. WEJ is a really difficult variety to get ahold of here! It seems like it isn’t hard to find imported but when I try to order from a grower it is sold out before I can check out (a matter of minutes). Thank you for sharing this! I already reordered them for next year, but my Painted Desert and Pam Howden look like this. I will use more caution thanks to you! ❤️
Thanks Adrienne, I can see you are a keen dahlia grower. WEJ tubers seem easy to get hold oh here in the UK, but I am not sure yet if I will risk growing them again. The virus seemed specific to this variety so fingers crossed no more plants will be affected. Frost not due this week here, but can't be far away! Kind regards, Peter
Hi Steven thanks for your question (I noticed you posted the same question against two videos so I will post the same answer in both.) It is not usual to change to soil after removing a plant with a virus, but you not place the same variety back into that soil. Dahlia viruses tend to be limited to one variety only (although it's not impossible to spread to others) . If it affects one plant only, then remove that plant immediately and burn or dispose and sterilize all instruments used. Carefully monitor nearby plants for the remainder of the season for similar symptoms and be ready to act quickly. Viruses are incurable but can be managed in this way to limit their damage. Hope this helps
Mine are nice and big and green but they have deformed leaves. I wasn't sure if it's a nutrient problem or virus? I think judging from your detailed video it may be a nutrient issue though. Thank you :)
Hi Valkyreve, thanks for your comment. Deformed leaves can be due to many causes so you should look for other signs such as leaf colour change or signs of infestation. I would say nutrient deficiency is low down on the list of possibilities from experience.
@@MoorfieldFarmFlowers Oh.. now I'm scared again :p They seem green enough, no yellowing and apart from grasshoppers and cabbage moth caterpillar thingies, no other bugs.
Hi thanks for your question. We replant in the same beds each year, although we rotate the varieties in any one spot. In instances of disease such as Virus or Gall, it is normal practice to avoid using the same spot, or attempt to replace the soil. Hope you have a great season.
Hi Maria thanks for commenting, I sympathize with you they can make a horrible mess of petals. The only method of control I would use is the upside down plant pot and straw on poles to reduce numbers.
Thank you. Will check my dahlias too.
Thanks for commenting Jacqui.
Many thanks for your advice, I have never seen this virus before. Regards Ken

Thanks Owen, yes that's good advice as newly bought stock can bring in a virus.

When you have removed the virus plant and tuber from the ground do you treat the ground it was in, or remove the soil in that area as well

Viral infections do not live in the soil. Bacterial infections (such as crown gall) would require changing soil.

Thanks Yesid
I’m growing dahlias in containers. Do I need to throw out the soil that the contaminated plant was in?
Hi Thanks for your question. Most growers would advise that, yes. I hope things work out for you.
Mine are nice and big and green but they have deformed leaves. I wasn't sure if it's a nutrient problem or virus? I think judging from your detailed video it may be a nutrient issue though. Thank you :)

@@MoorfieldFarmFlowers Oh.. now I'm scared again :p They seem green enough, no yellowing and apart from grasshoppers and cabbage moth caterpillar thingies, no other bugs.
I wish I could help more. other options are: water deprivation, physical damage (heat or cold) and herbicide contamination.
@@MoorfieldFarmFlowers Thanks so much for replying with your advice. Much appreciated :)
You're welcome :)
Can you replant dahlias in the same spot?
Hi thanks for your question. We replant in the same beds each year, although we rotate the varieties in any one spot. In instances of disease such as Virus or Gall, it is normal practice to avoid using the same spot, or attempt to replace the soil. Hope you have a great season.
My problem is the earwigs eating and laying their eggs on my Dahlias.
