This profile contains verified disease data from extension databases. Regional field notes and expert review are in progress.
Camellia leaves show genetic white or pink stripes or viral irregular white spots, mottles, and ringspots depending on cause. Viral variegation produces symptoms that vary yearly and irregularly across branches. Neither genetic nor viral forms harm plants; some growers desire them. Use virus-tested stock if unwanted. Check soil pH and provide supplemental iron if yellowing becomes problematic.
If the viral variegation is not desired, then purchase virus-tested (and found to be free of all known viruses) plants to start. Check soil pH which should be between 5.5 and 6.5 if yellowing leaves are a common and consistent problem on bushes.

Management
Cultural Controls
- Water management that minimizes excessive water around the root crown is critical for management of this disease. Locate orchards on well-drained slopes if possible. Tile orchards or sites with poor drainage. Plant on a raised bed to help keep water away from trunks. Use resistant rootstocks.
