San Pedro Source Trichocereus Terscheckii

This cactus requires bright, direct sunlight to thrive. A south-facing window is ideal, as it needs several hours of unfiltered sun daily to maintain its structural integrity and avoid etiolation, or stretching.

No, this plant is not pet-friendly. It features sharp, prominent spines that can cause injury if touched, so it should be placed in an area that is inaccessible to curious pets and children.

As a highly drought-tolerant species, it requires very little water. Allow the soil to dry out completely between waterings, and significantly reduce frequency during the winter months when the plant enters dormancy.

While the Trichocereus terscheckii can reach 10-20 feet in its natural habitat, its growth is significantly slower and more contained when grown in a container. It will remain a manageable size for an indoor space for many years, though it will eventually require repotting as it matures.

Use a well-draining cactus or succulent potting mix. You can improve drainage further by adding perlite or coarse sand to ensure water does not pool around the roots, which is critical for preventing rot.
