Dinteranthus wilmotianus are mimicry succulent plant with reduced leaves which look like, both in colour, texture and shape, the grey stones and pebbles found in their natural homes. Their very particular structure and colours have developed in order to allow them to live in the harsh conditions of their natural environment. It is usually solitary or few branched, with 3-5 branches each with a single leaf-pair in the resting state.
Dinteranthus are summer growing species with dry rest period over winter but they do not shows an apparent dormant season like Lithops. Easy to grow they need a very open mineral, fast draining mix with little compost and a high degree of grit, coarse sand, small lava gravel or pebbles. Give them the maximum amount of light you are able to give them, but care should be taken about exposing them to the full blast of the sun rays in summer (The only exception to this is seedlings in their first year that enjoy a shades place) . Such tiny plants can easily get scorched or broiled and their appearance spoiled (this may not matter in the wild, where the Dinteranthus have probably shrunk into the ground and becomes covered with sands). The basic cultivation routine is: Gives some water all year, more in Spring and again in autumn. Keep rather dry during coldest winter month and start watering regularly after the old leaves completely dry. (Usually late March or Early April) Water freely during the growing season, soak the compost fully but allow it to dry out between waterings. Some growers fertilize frequently, some hardly ever. Nearly all problems occur as a result of overwatering and poor ventilation especially when weather conditions are dull and cool or very humid. If too much water is supplied the plants will grow out of character, bloat, split and rot. Keep them in small pots as solitary clumps or as colonies in large, shallow terracotta seed pans. When in doubt DON'T WATER. Where the resting season is in the winter and central heating gives very dry air in the home, give a light top spray once a week to simulate the desert dew and prevent excessive dehydration. Overwinter them preferably not below 5° C (but they endure some freeze if very dry).
