Cultivation and Propagation: Parodia formosa is an easy to grow tropical cactus, more cold tolerant than most and less fussy regarding soil conditions. Growth rate: It is a relatively rapidly growing and easily flowering species that will make clumps given the best conditions. Soils: It likes very porous standard cactus mix soil. Repotting: Use pot with good drainage. Watering: Water regularly in summer, but do not overwater (Rot prone), keep dry in winter. Fertilization: Feed with a high potassium fertilizer in summer. Hardiness: Reputedly sensitive to frost, but less so if kept on the dry side prior to, and during, cold weather (hardy to -5° C for short periods). However warmth throughout the year will increase the grower's success (8-12°C during rest season). Exposition: Outside bright but partially filtered sunlight or afternoon shade, inside it needs bright light, and some direct sun. Subject to sunburn if exposed to direct sun for too long. Tends to bronze in strong light, which encourages flowering and heavy wool and spine production.
