Why does your Calathea crocata have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyCalathea crocata is native to tropical environments and requires high humidity levels. When the air is too dry, the plant struggles to maintain moisture in its foliage, often causing leaves to lose their vibrant color and turn yellow.
Excessive moisture in the substrate prevents oxygen from reaching the roots of the Firestarter. This leads to fungal pathogens attacking the root system, which manifests as yellowing leaves that may feel soft or limp.
As a rapid grower, Calathea crocata can deplete essential minerals from its potting medium. A lack of nitrogen specifically causes older leaves to turn yellow as the plant redistributes nutrients to new growth.
This species is sensitive to the fluoride, chlorine, and salts found in municipal tap water. Accumulation of these minerals in the soil can cause leaf chlorosis and tip burn.
