KR 04 (Cuttings)

All cuttings will be thick and ready to root. Please allow 5-7 days to dry if fresh cut.

'KR04' is a specific cultivar of Trichocereus, often discussed in communities dedicated to these cacti. While it shares many general care and propagation requirements with other Trichocereus varieties, there are some anecdotal observations about its specific characteristics.

Here's a breakdown of what's known about 'KR04' cuttings:

General Characteristics of Trichocereus (and 'KR04' by extension):

Columnar Growth: Like most Trichocereus species (e.g., T. Pachanoi, T. Bridgesii), 'KR04' is a columnar cactus, meaning it grows upright in a column shape.

Appearance: It's generally described as a "short spine pach" (a type of T. Pachanoi). Some users note it's not always the most visually striking compared to other varieties, but it can grow flawlessly.

Origin: While specific origin details for 'KR04' are not widely published, Trichocereus Pachanoi (San Pedro cactus) is native to the Andes mountains in Ecuador, Peru, and Colombia.

Hardiness: Trichocereus are generally hardy and can withstand temperatures lower than many other cacti, especially if kept dry during cold periods. They prefer fertile, free-draining soil.

Growth Rate: Trichocereus can be fast-growing, with some varieties growing up to 30 cm per year. While one user found 'KR04' to be slow initially, others reported it as a good, vigorous grower, especially when grafted.

Specific Observations about 'KR04':

Rooting: Some growers have reported that 'KR04' can take longer than average to root, but once established, it grows well.

Resilience: It seems to be relatively resistant to fungal and humidity issues for some growers, even thriving outdoors in humid climates like North/Northeast Texas. However, one grower noted it was "very fickle, prone to root rot and humidity spots" before grafting. This suggests that good cultivation practices are crucial for its health.

Growth on Own Roots vs. Grafted: While it can thrive on its own roots, some growers have noted faster growth when 'KR04' is grafted onto a more vigorous rootstock (like Trichocereus brevispinulosus or PC San Pedro).

Alkaloid Potency (Anecdotal): There's discussion in forums about its potency, with some reporting it tested well (e.g., almost 3% mescaline), while others found it less impressive than faster-growing, slightly lower-potency varieties.

Cultivation and Care for 'KR04' Cuttings (General Trichocereus Care):

Cutting Preparation:

Choose a healthy, mature segment of the cactus, ideally 6-24 inches long.

Make a clean, straight cut with a sharp, sterile knife.

Callusing: This is crucial. Place the cutting in a bright, well-ventilated, dry location for at least 2 weeks (or until a firm, white callus forms on the cut end). This prevents rot.

Optional: Apply rooting hormone to the callused end.

Planting the Cutting:

Soil: Use a well-draining cactus mix. A common recommendation is at least 50% inorganic material (pumice, perlite, horticultural grit, sharp sand) to 50% organic material (potting soil, compost, coco coir). Good drainage is paramount to prevent root rot.

Potting: Plant the callused end about 1-2 inches deep (deeper for taller cuttings to ensure stability). You can use rocks or bamboo stakes for extra support until roots develop.

Initial Watering: Do not water immediately after planting. Wait 4-8 weeks (or until you see signs of new growth or feel resistance when gently tugging) to encourage root development. The cutting will use its stored water and may shrivel slightly, which is normal.

Ongoing Care (Once Rooted):

Sunlight: Trichocereus prefer full sun during their growing season (spring to early fall). Introduce them gradually to full sun if they've been in lower light to prevent sunburn. If grown indoors, a south-facing window with good airflow and supplemental grow lights is recommended.

Watering: Water thoroughly when the soil is completely dry and the cactus feels slightly softer or deflated. During the growing season (April to October), this might be once or twice a week. In fall and winter, reduce watering significantly or stop altogether as the plant enters dormancy. Overwatering is a common cause of rot.

Fertilization: Fertilize during the growing season (spring and summer), typically every other watering, with a balanced NPK fertilizer or one with lower nitrogen. Avoid fertilizing in winter.

Temperature: Protect from frost (below 30°F / -1°C). Bring indoors or use frost blankets if temperatures drop.

Pests and Fungal Issues: Inspect regularly for pests like mealybugs, scale, and mites. Ensure good airflow to prevent fungal issues. Well-draining soil and fungicides can also help.

Propagation Methods:

Cuttings (as detailed above): This is a popular and effective method.

Grafting: Attaching a 'KR04' cutting (scion) onto a robust rootstock can promote faster growth and is often used for less vigorous or sickly specimens.

Seeds: While possible, growing from seeds is a much slower process than propagating from cuttings.

In summary, 'KR04' is a Trichocereus cultivar that, while perhaps not always visually striking, has a good reputation among some growers for its resilience and potential potency. Successful cultivation hinges on providing excellent drainage, appropriate sunlight, and careful watering, especially during the rooting phase and dormancy.
