What's Wrong with My Chinese Evergreen?

Chinese Evergreen has fine roots that suffocate quickly in waterlogged soil. When they rot, the plant pulls nutrients back from the lowest leaves first, and yellowing climbs up the stem. The broad leaves mask the early stages, so by the time yellowing is obvious the roots may already be in bad shape.

Chinese Evergreen is a tropical plant from Southeast Asian rainforests and cannot handle temperatures below 60°F. Cold air from a vent or drafty window triggers rapid yellowing, often affecting multiple leaves at once rather than moving up from the bottom like overwatering does.

As Chinese Evergreen matures and produces new leaves at the top, it sheds the oldest ones at the base of the stem. This is normal. If just one or two of the lowest leaves are yellowing while new growth looks healthy at the top, the plant is fine.

Chinese Evergreen evolved in humid Southeast Asian rainforests and struggles when indoor air drops below 40% humidity. The leaf tips brown and crisp first because they are the furthest point from the water moving up the stem.

Chinese Evergreen is one of the more fluoride-sensitive houseplants. Fluoride in municipal water accumulates in leaf tissue over time and causes tip browning that looks similar to humidity damage, but often appears on younger leaves too rather than just the oldest ones.

Chinese Evergreen's broad leaves lose water steadily. When the pot dries out completely, the plant cannot maintain pressure in its stems and the leaves go limp and hang. Recovery is usually fast once the plant gets a thorough drink.

Cold drafts below 60°F cause rapid tissue damage in Chinese Evergreen's tropical foliage. The plant droops suddenly and the affected leaves may also yellow or develop water-soaked patches within a day or two of exposure. If the soil is not dry but the plant is drooping, cold is the first thing to check.

Chinese Evergreen is marketed as a low-light plant, but the pink, red, and silver varieties need more light than the plain green ones to keep their color. In dim conditions the new leaves come in duller and greener as the plant prioritizes chlorophyll production over pigmentation. The effect is gradual and most visible on new growth.

In direct sun, Chinese Evergreen's patterned leaves lose contrast as the pigment breaks down. The variegated areas wash out to a pale, bleached look and the leaf surface may feel dry or slightly papery. This is the opposite problem from dim light but it affects the color the same way.

Fine webbing on leaf undersides and pale stippling on the upper surface are the main signs. Chinese Evergreen's broad, slightly waxy leaves can hide an early infestation until webbing appears along the midrib. Dry indoor air in winter is the trigger, and the dense leaf canopy gives mites shelter to multiply.

White cottony masses in the joints where leaf stems meet the main cane. Mealybugs are attracted to the soft, moist leaf axils that Chinese Evergreen produces and hide deep in the crown where casual inspection misses them. They suck sap and leave sticky honeydew that trails down the stem.
