Propagation is a rewarding endeavor, allowing enthusiasts to expand their Trichocereus collection and even share their passion with others. Whether you're a seasoned hobbyist or a novice eager to delve into the world of cacti propagation, this guide will illuminate the path for you.

1. Propagating from Cuttings

Selecting the Cutting: Choose a healthy segment of your Trichocereus cactus. Ensure it's free from pests or diseases. Popular choices for propagation include Pachanoi, Bridgesii, and Peruvianus.

Preparation: Use a clean, sharp knife to make the cut. Let the cutting dry for a few days to form a callous, which prevents rotting when planted.

Planting: Once the callous has formed, plant the cutting in a well-draining soil mix. Bury about a quarter of its length into the soil.

Watering: Wait for a week before watering to ensure the cutting has started rooting. Then, water sparingly until the plant establishes itself.

2. Propagating from Seeds

Sourcing the Seeds: Varieties like Scopulicola and Chalaensis can be propagated from seeds. Always ensure you source seeds from a reputable vendor, like The Succulent Source.

Planting: Use a mix of sand and compost as your substrate. Spread the seeds evenly and cover them lightly with sand.

Watering: Use a spray bottle to keep the soil consistently moist but not waterlogged.

Germination: Place the container in a warm, shaded area. Patience is key, as some seeds might take weeks to months to germinate.

3. Grafting for Faster Growth

Grafting involves attaching a piece of one cactus (scion) to another (rootstock) to encourage faster growth.

Selecting Scion and Rootstock: Varieties like Monstrose or Crested can benefit from grafting. The rootstock should be robust and well-established.

Technique: Make flat cuts on both the scion and the rootstock. Attach them, ensuring the vascular tissues align. Secure with rubber bands until they fuse together.

4. Tips for Propagation Success

• Soil: Ensure it's well-draining. Cacti are prone to root rot if they sit in waterlogged soil.
• Light: While Trichocereus cacti love light, newly propagated plants should be kept away from direct sunlight to prevent scorching.
• Patience: Especially when propagating from seeds, patience is paramount. Some plants might take longer to show signs of growth.
