====== MK ======

===== Description =====
The "MK" designation refers to a series of distinct Trichocereus clones (including MK01, MK08, MK09, MK111, and MK333) distributed by the grower Matt (MK). Because "MK" represents a collection of diverse clones rather than a single cultivar, botanical characteristics such as rib count, spine length, and epidermis color vary significantly depending on the specific numbered clone. 

===== History & Origin =====
The majority of the MK collection is reported to have originated from an older European collector who spent decades traveling to South America to collect wild cuttings. Matt (MK) reportedly acquired a single cutting of each clone from this collector shortly before the original collection was destroyed. The clone "Monika" is also associated with this source, having been obtained from the garden of a woman named Monika, though it does not carry an official MK number.

===== Cultivation Notes =====
No clone-specific cultivation requirements were detailed in the community discussion. Standard cultivation practices for Trichocereus species are recommended: utilize a highly porous, well-draining soil mix, provide deep watering only when the substrate has completely dried, and ensure ample direct sunlight to maintain typical glaucous coloration and robust spination.
