Mother-in-law's tongue (Sansevieria) is a succulent plant that will add interest indoors all year round with a minimum of time and attention. Mother-in-law's tongue, also known as snake plant because of its dark green, sword-shaped leaves, will do fine in nearly any environment and can even withstand occasional neglect from busy gardeners.
Plant mother-in-law's tongue in a container with good bottom drainage. Use a commercial potting soil formulated for cactus mixed with half perlite.
Place mother-in-law's tongue in full sunlight. Although the plant will grow in lower levels of sunlight, it will thrive in bright light.
Allow the potting mixture to dry out between waterings. Usually, mother-in-law's tongue should be watered no more than once a week. During the winter months, water sparingly, no more than once a month. Mother-in-law's tongue, like all succulents, is prone to rot in excessively moist soil, especially in cool weather.
Fertilize in early spring, early summer and early autumn, using a general-purpose liquid fertilizer for indoor plants. Withhold fertilizer during the winter months.
Repot every one to two years, as the plant's roots grow rapidly and can break the pot if it becomes root-bound. Move the plant to a container one size larger.
