Why does your Mini rose Lipstick Jewel have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Miniature roses are highly susceptible to root rot if the potting medium remains saturated. Excess moisture displaces oxygen in the soil, leading to chlorosis (yellowing) of older leaves as the roots fail to transport nutrients.
As a heavy feeder, 'Lipstick Jewel' requires consistent nitrogen for chlorophyll production. A lack of nitrogen causes the lower, older leaves to turn pale yellow first while growth remains stunted.
If the soil pH is too high (alkaline), the rose cannot absorb iron. This results in interveinal chlorosis, where the leaf tissue turns yellow but the veins remain dark green.
Tiny spider mites thrive in the warm, dry conditions often preferred by miniature roses. They pierce cell walls to feed, causing leaves to lose chlorophyll and eventually turn yellow or develop a bronzed appearance.
