PegMc I've scrolled through all of the Dahlia Virus photos online and didn't find anything that looks like this. The closest I got was a photo portraying a magnesium deficiency but that doesn't seem to fit either. This is one of my seedlings. Another one looked identical to this and I destroyed it. This time I decided it best to ask. It would have been smart if I'd taken it away from those danged pink lights. The white is not quite snow white, but darned close. The green of the leaves is a solid dark-ish green. Thoughts?
Krista PegMc I don’t have the answers you’re looking for but wouldn’t it be amazing if you just hybridized the first (technically second) dahlia with such dramatic, variegated foliage?!
Bessie PegMc in another discussion thread there's a conversation regarding fertilizer. That reminded me, What became of the plant that was sick? I had some plants with similar symptoms, and at this point they look normal. I read that Manganese deficiency can be brought on by over watering and ph imbalance. I think my plants had been over watered The four plants I grew that looked similar to yours outgrew the problem and are now at this point looking normal. I did continue to fertilize them.
Cosey I had a seedling that would randomly throw a white leaf. The white leaves just burn up in the field under natural UV. These iffy photosynthesizing plants never do well. But what can hurt from trying? 🤷
Juliarugula I haven’t had a dahlia with foliage like this, but many other plants that throw out occasional white foliage tend to burn up in the sun like Cosey said. I probably wouldn’t bother. But if I did plant it out of curiosity, I would be prepared for certain death. (Dramatic Bum bum bum..)
Bessie Ok, I wasn't going to put in my opinion, but since others have ... I would fertilize with a product that contained manganese. The young leaves being white, with green veins is a textbook manganese deficiency.
