Turbinicarpus valdezianus (10 seeds)

This is one of 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.
 
Cultivation: It’s a fairly easy species to cultivate, but very slow growing. It needs a very well-drained soil, and requires strong sun to part sun where it obtains a flat natural look. Waterings should be rather infrequent to keep the plant compact, and avoid its becoming excessively elongated and unnatural in appearance. Furthermore it has a tap root, and watering it properly is often difficult, because it tends to crack open or rot if over-watered. Keep dry in winter, or when night temperatures remain below 10° C. It is hardy to -4°C for a short period.  Assure a good ventilation.

All seeds are fresh of this season and obtained from my personal collection.

(NOTE: cactus seeds could be sown in any season under control environment, however if you wanna go with nature then best time to sow the seeds is early spring/summer )
