Named Watermelon for its similarity of appearance to the rind (skin) of a watermelon. Leaves are oval in shape with a mixture of green and silver stripes, attached to thin non-woody red stems. They grow up to 9-10 inches tall.
A bright room with the plant placed in a shaded spot is ideal, without direct sunlight. Yet, too much light fades the bright colors of the variegated foliage. West, east or even south facing window is best. Direct, intense sunlight will burn the leaves.
Peperomia Watermelon is a tropical plant that prefers humid conditions but is prone to stem rot in soggy soil. Water the plant deeply when the top of the soil feels slightly dry. Let the pot drain completely and never allow the plant to stand in water. In fall and winter, water sparingly and allow more time between each watering so the soil has time to dry a bit more than usual. If the air is dry in summer or heater is on in winter, increase humidity by setting the container on a tray with a layer of wet pebbles.
During the growing season in spring, use a diluted liquid fertilizer once every 2 - 4 weeks until the end of summer.
Watermelon peperomia does not tolerate freezing temperatures. Bring it in as soon as night time temperatures drop to below 10 C.
