TPM (Rooted Plants)

TPM: This acronym commonly refers to "Trichocereus Pachanoi Monstrose" or sometimes "Trichocereus Peruvianus Monstrose."

What does "Monstrose" mean?

"Monstrose" describes a type of abnormal growth in cacti where the plant develops in a contorted, bumpy, and oddly shaped manner, rather than the typical columnar growth. This unique morphology is due to the emergence of multiple lateral meristems (growing points) instead of the usual single, tip-driven expansion. It can be caused by various factors, including:

• Genetic mutations (which is the case for TPM)

• Physical injury

• Viral mutations

• Environmental stress (though the underlying genetic predisposition is key for consistent monstrose growth)

Key Characteristics of "Cactus CV TPM":

• Unique Aesthetics: TPM cacti are highly sought after by collectors for their distinctive, often "funky" or "brain-like" appearance, with irregular bumps, notches, and sometimes smooth patches.

• Reversion and Cresting: A fascinating aspect of TPM is its tendency to "revert" to normal columnar growth at times, or even to "crest" (cristate growth), which is another type of abnormal development where the apical meristem expands linearly, forming fan-like or wavy patterns. A single TPM plant can display all three growth forms: normal, monstrose, and crested.

• Hardiness: Like many columnar Trichocereus species, TPM is generally quite hardy and tolerant of varying conditions, including cold snaps (as long as the soil is dry in winter).

• Growth Rate: Many growers report that TPM is a fast-growing cultivar, often producing many "pups" (new shoots) and gaining size quickly.

• Common Origin: While "TPM" can generally refer to any monstrose Trichocereus pachanoi, a widely recognized clone often seen in nurseries and big box stores is attributed to Altman Plants.

Care and Cultivation:

• Light: Keep in part-shade when young, gradually increasing sun exposure as the plant matures. Established Trichocereus species can handle full sun.

• Watering: Water regularly during the growing season, but allow the soil to dry out between waterings. Reduce watering significantly in colder months or when the plant is dormant. Avoid overhead watering in cold or humid conditions to prevent rot.

• Soil: Requires well-draining soil mixes, often a mix of soil and perlite or other mineral components.

• Fertilization: Fertilize regularly with a balanced fertilizer (like fish emulsion/seaweed at half strength) during the growing season.

In summary, "Cactus CV TPM" refers to a specific, highly variable and aesthetically appealing monstrose cultivar of Trichocereus pachanoi (or sometimes peruvianus) that is popular among cactus enthusiasts due to its unique growth patterns and resilience.
