Pelecyphora Valdeziana Description: Turbinicarpus valdezianus is one the smallest and slowest growing Turbinicarpus with tiny feathery spines that obscure the body of the plant, it is usually solitary but sometime form clusters of few branches.
Stem: Young plants are spherical, then cylindrical with a narrower base and short spirally arranged tubercles, the apex is completely covered by the plumose spination. Typically half of it is underground with a big tap root. The plants are about 3-5 cm high and 1-2 cm in diameter.
Spines: Turbinicarpus valdezianus is a pectinate-spines species, but the the pectinate spines are not in the two neat rows as in Turbinicarpus pseudopectinatus, the ca. 25-30 spines, are dense, feathery and white, about 0.5 mm long, spreading flat around the areoles.
Flowers: One to 5 diurnal, at plant apex. This species is found scattered in small populations in several locations and the colour of the flowers is variable ranging from pinkish-white to bright pink with darker magenta or reddish-brown midveins.
Blooming season (in habitat): T. valdezianus is an early bloomer (February – March).
Cultivation and Propagation: Turbinicarpus valdezianus is not particularly difficult on own roots, but very slow growing.
Soils: It likes very porous standard neutral or slightly alkaline cactus mix soil.
Repotting: Use pot with good drainage.
Watering: It should be watered during the growing season, but waterings should be rather infrequent to keep the plant compact, and avoid it will become excessively elongated and unnatural in appearance. Keep dry in winter or when night temperatures remain below 10° C. Water it less than average if in bigger pots, small pots preferred. Furthermore it has a tap root, and watering it properly is often difficult, because it tends to crack open or rot if over-watered. Careful watering away from the body of the plant will allow the areoles to keep their wool.
Fertilization: Feed with a high potassium fertilizer in summer.
Hardiness: It is hardy to -4°C for a short period if kept on the dry side prior to, and during, cold weather. However warmth throughout the year will increase the grower’s success (8-12°C during rest season). Assure a good ventilation.
Exposition: Outside bright, hot conditions or afternoon shade, inside it needs bright light, and some direct sun. Strong light keep the plant compact and low and encourages flowering and heavy wool and spine production.
