Light: Escobaria love to be in a very bright exposure, but generally not to direct light of sun: the risk, especially during the hottest hours of the day and during the summer, is to get sunburned. Soil: The soil to grow Escobaria, needs to be well drained, porous and aerated. Despite being small in size, the plants develop a branched root system with extremely thin and fragile tubercles: the fragility of the radical apparatus constitutes a preferential route for the development of mold and rot, in the presence of moisture excess. Temperature: The average winter minimum temperature, in general, should not fall below 42 to 46 °F (6 to 8 °C), unless individual exceptions; adult plants can withstand frosts also very intense, but only if the temperature rises again quickly. Some species, due to the natural environment in which they were born and grew up, developed characteristics of extreme resistance (Escobaria minima resists up to 18 °F (-8 °C), Escobaria vivipara and Escobaria missouriensis resist even down to -4 °F(-20 °C), in completely dry soil conditions and low humidity): for this reason the Escobaria are considered, with precautions, as winter resistant.
