Haworthia emelyae var. picta belongs to one of most attractive species and is sought after by collectors for its beautifully marked solitary rosette, the leaf tips are nicely spotted and turn a tan colour in strong light. Vaguely reminding in outline for a Haworthia retusa, this handsome little gem differs by the prettily marked leaf faces and the etchings of white showing well against the darker green of the leaves. It is for this reason the plant was named, picta “the painted”.
Haworthia are of easy cultivation and relatively low maintenance, which makes them a good houseplant, and can be an excellent subject for the beginning succulentophile (they can grow easily on window sills, verandas and in miniature succulent gardens where they are happy to share their habitat with other smaller succulent plants, or in outdoor rockeries). Haworthias are winter growers and are dormant in the hottest summer months. Growth rate: Haworthia picta is one of the slowest-growing species. Soil: They are tolerant of a wide range of soils and habitats, but prefer a very porous potting mix to increase drainage. A non-acid soil is ideal. You can grow a plant in a 10-15 cm pot for years and have perfectly happy plants. For best results, use a shallow pot. Exposition: The plant needs light shade to shade, but will take full sun part of the day. (with some sun exposure the leaf develops a nice reddish tint and remains compact). Watering: During the hot summer months, the soil should be kept moist but not overly wet. During the winter months, water only when the soil becomes completely dry. Wet soil quickly causes root and stem rot, especially during chilly winter months. No water should ever be allowed to stand around the roots. Low ambient humidity is always needed. Fertilization: The plants are fertilized only once during the growing season with a balanced fertilizer diluted to ½ the recommended strength. Hardiness: Although the plant will survive mild frost if kept dry (hardy as low as -5° C) it should be protected from severe cold and prolonged frost conditions.
