Why Did The Leaves Of My Zebra Plant Became Dark?

Is your zebra plant placed in drafty or dry location?

Zebra plant is prone to suffer from root rot when potted in containers without proper drainage. Too much water leads to rotting roots, stems, and leaves and blackening of leaf surfaces when the disease progresses far enough. Avoid root rot by only planting in pots with drainage holes and by keeping the soil consistently moist, but never soggy.

Sometimes, root rot can occur even if your potting soil is well-drained. This usually happens when the owner water his plant excessively. Zebra plant needs consistently moist soil, but never allow it to be flooded. You can achieve this by checking if the top inch of the soil had dried up before watering. Water only when the top inch is dry to the touch.

Zebra plant is susceptible to two types of leaf spots, both of which cause these symptoms. Severe leaf spot usually isn’t a problem for houseplant growers and can often be resolved by eliminating overhead watering.

Zebra plants often suffer scorch, with drying, browning and cracking leaves, when they are placed in drafty or dry locations. Because they appreciate high humidity and warm growing temperatures of at least 65 degrees Fahrenheit, you must be sure to keep them somewhere warm and wet. If your house has low humidity, try placing zebra plant pots on a tray filled with pea gravel and water, refilling as needed to keep water at the gravel line.

When zebra plants are chlorotic, their older leaves often get darker than usual while younger leaves appear a lighter than usual or even yellow. If leaf darkening is accompanied by yellowing, chlorosis may be the problem, which usually results from a nutrient deficiency. For zebra plants, use an all-purpose soluble fertilizer diluted to half the recommended strength every month.
