Genus that brings together some cactaceae, generally globose in shape and of small size, originating in Central America. They have low tubercles, with spiny areoles, and often curved ribs; in spring they produce small flowers in shades of yellow and pink, whose pericarp often bears some scales, more rarely fluff. In summer it produces roundish little fruits and small dark seeds, sometimes crested. T. pseudopectinatus has thorns arranged like a comb, hence the name. T. krainzianus is dark green with spiral ribs.
T. ysabelae has white flowers suffused with pink, and slightly curved spines: T. lophophoroides has a similar appearance to a lophophora, in fact.
Particularly like very bright positions, even if they develop without problems even in partial shade. THE Turbinicarpus they must be placed outside in spring and summer, while in the cold months they are admitted to a protected place, at home or in a temperate greenhouse, even though they can easily bear even light and short frosts, especially if the soil is dry.
They need frequent but moderate watering in spring and summer, checking however that the soil dry between one watering and another; in the cold months it is advisable to thin the waterings, especially if the plant is cultivated in a place with temperatures below 10 ° C; if you decide to repair them in a cold greenhouse it is advisable to completely suspend the watering throughout the winter, to allow the plant to go into the resting phase. In the vegetative period, from March to September, provide the fertilizer plant for succulent plants dissolved in the water of the watering every 15-20 days.
Turbinicarpus: The type of soil
Like many other cactacee also i Turbinicarpus they do not need particularly fertile soils, the important thing is that the substratum is very well drained, to avoid water stagnations that are very harmful to fat plants in general, usually used in deserts; to obtain an ideal compost we can mix peat, sand and universal soil in equal parts, with additions of coarse material, both on the bottom of the pot and in the soil itself, we can use expanded clay, perlite or pumice stone for this purpose. species produce numerous basal shoots, which can be detached from the mother stone to constitute new up-to-date seedlings; otherwise the multiplication can take place by seed, in spring. Pests and diseases: if the watering is excessive, the appearance of root rot can be favored; sometimes the turbinicarpus are attacked by aphids or cochineal.
