Why does your Rosa Yellow Ovation have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
In miniature roses, yellowing between the veins (interveinal chlorosis) while veins remain green is a classic sign of iron deficiency, often caused by high soil pH preventing uptake.
Excessive moisture in the small, dense pots used for 'Yellow Ovation' leads to anaerobic conditions, causing the roots to rot and preventing the transport of nutrients.
A lack of nitrogen causes older, lower leaves to turn a uniform pale yellow before eventually dropping from the canes.
While typically known for dark spots, the fungal pathogen *Diplocarpon rosae* can cause premature leaf yellowing as the plant attempts to shed infected tissue.
