Why does your Maranta arundinacea variegata have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyMaranta arundinacea is highly susceptible to fungal pathogens like Pythium if the rhizomes stay too wet. Excessive moisture prevents oxygen from reaching the roots, leading to yellowing of older leaves as the root system fails.
As a tropical rhizomatous plant, variegated varieties have higher metabolic demands for nutrients. A lack of nitrogen or magnesium prevents chlorophyll production, causing the characteristic yellowing between leaf veins.
Variegated Maranta species lack the dense chlorophyll of green varieties, making them more sensitive to transpiration stress. Dry air or infrequent watering causes the leaf margins to yellow and eventually crisp.
While variegation requires light, too much direct sunlight can damage the delicate variegated cells in Maranta arundinacea. Intense light causes the pigments to break down, resulting in yellow or bleached patches.
