Trichocereus bridgesii (Echinopsis lageniformis): A Comprehensive Guide to Cultivation, Identification, and Professional Management
Trichocereus bridgesii (commonly referenced in modern literature as Echinopsis lageniformis; also known in the commercial sector as "Bolivian torch") is a columnar cactus native to Bolivia, highly valued for its elegant growth habit, vigor, fragrant nocturnal flowering, and excellent adaptation to dry high-altitude climates. At TRICHOLAND, we produce selected material for nurseries and landscaping, with a special focus on uniformity, health, and performance in intensive cultivation.
This guide compiles expert management advice for advanced enthusiasts and professionals, covering taxonomy, identification, habitat, high-performance substrates and watering, nutrition, cold tolerance, propagation, plant health, differentiation from related species, and an annual work calendar.
Taxonomy and Names
- Genus: Trichocereus (often included in Echinopsis in current treatments).
- Commonly accepted name: Echinopsis lageniformis (syn. Trichocereus bridgesii).
- Synonyms and affinities: some sources include nearby synonyms such as Echinopsis scopulicola and regional forms; treatment varies by author.
- Common names: "Bolivian torch"; various vernacular names are registered in Bolivia.
- Common misspelling: “bridgessii.” Correct form: bridgesii.
Origin and Habitat
- Distribution: departments of La Paz, Cochabamba, Tarija, and Chuquisaca (Bolivia).
- Altitude: approximately 1,000–3,300 m a.s.l., found on slopes and ravines with well-drained stony soils.
- Climate: distinct dry and wet seasons, high radiation, broad daily temperature range, and seasonal rainfall.
Description and Identification
- Growth habit: bushy to tree-like, occasional branching; typically 2–5 m in height under ideal conditions.
- Stems: light green to glaucous-blue, 15–20 cm in diameter, with 4–8 well-defined ribs.
- Areoles: large, spaced ~1.5–3 cm apart.
- Spines: 2–6 per areole, unequal, honey to brown color, length ~0.1–7 cm (more robust in mature plants).
- Flowers: white, large, fragrant, nocturnal; with a long floral tube; ~15–20 cm in length.
- Fruits: spherical, with trichomes; ~4–6 cm in length.
Cultivation Requirements
Light and Exposure
- Light: full sun after gradual acclimatization. In nurseries, provide a shading mesh of 30–40% for young or recently transplanted specimens for 2–3 weeks.
- Indoor/Greenhouse: target PPFD 250–400 µmol/m²/s for maintenance; 400–600 for rapid growth with appropriate ventilation and nutrients.
- Wind: tolerant; guide until the base thickens in exposed locations.
Temperature and Cold Tolerance
- Optimal: 18–30 °C (active growth above 15 °C in the substrate).
- Resting: below 10–12 °C reduces activity; keep drier.
- Frost: safe cultivation recommended in USDA 9a–11. With expert management, mature specimens in very well-draining substrates can tolerate dips down to −4/−6 °C if dry. Avoid frost on wet soil.
Professional Substrate (Pot or Container)
Goal: rapid drainage, high aeration, and moderate retention for deep and spaced watering.
- 60–70% mineral fraction: pumice/volcanic gravel 2–8 mm, or washed coarse silica sand.
- 30–40% organic fraction: fibrous blonde peat or coco (medium mixture) + 10–15% screened mature compost.
- Correctors:
- Dolomite/Calcium carbonate: 2–4 g/L if using acidic peat (adds Ca/Mg and stabilizes pH).
- Mycorrhizae and Trichoderma during propagation for root vigor.
- Silicon (diatomaceous earth powder/orthosilicic acid) in microdoses for tissue firmness.
- Target pH: 5.8–6.5 (tolerance ~5.5–7.2). Avoid compacted or saline substrates.
- Drainage: pots with multiple holes or slats; a layer of aggregates in the base does not substitute for a proper substrate.
Watering
- Spring–Summer: deep watering, allowing 50–80% of the substrate volume to dry between watering. In pots: 1 watering every 5–10 days depending on temperature, radiation, wind, and container size.
- Autumn: space progressively; prioritize light watering on warm days if residual heat remains.
- Winter: in cold climates, keep almost dry. In frost-free areas, very occasional and light watering.
- Water quality: low EC (0.75 dS/m) and moderate alkalinity. If the water is hard, acidify to pH 5.8–6.2 to prevent chlorosis.
Nutrition and Fertigation
- Working dosage during active growth: 50–100 ppm of N per application every 2–4 waterings with low-N formulations and high K (e.g., 3-5-7 / 4-7-8) + chelated micronutrients (Fe, Mn, Zn).
- Conductivity in solution: 0.8–1.2 mS/cm at peak growth.
- End of summer: reduce N; prioritize K, Ca, and Si for tissue maturation.
- Salt leaching: every 6–8 weeks, abundant irrigation with clear water.
- Avoid urea as the main N source; prefer ammonium nitrate/calcium nitrate.
Pots, Transplanting, and Structure
- Container: deep with excellent lateral aeration; performs well in slotted/air pots.
- Transplanting: when the root ball occupies >80% of the volume (approximately every 2–3 years). Best time: late spring–summer.
- Support: cane/stick and elastic ties to avoid strangulation until the base is established.
Propagation
Cuttings (Preferred Method in Nurseries)
- Selection: healthy segments of 20–40 cm with firm tissues.
- Cuts: clean and slightly beveled, using disinfected tools.
- Curing: vertical, in bright shade and ventilation for 10–21 days until a dry callus forms. In humid climates, dust sulfur on the cut.
- Rooting: place on very mineral and slightly moist substrate; first moderate watering after 2–4 weeks or when roots are visible (>2–3 cm).
Seeds
- Substrate: fine and sterile (e.g., 50% fine silica sand + 50% screened peat/coco). Disinfect with heat.
- Sowing: superficial; maintain high humidity under a dome; provide intense diffuse light.
- Temperature: 22–28 °C. Germination typically occurs in 7–21 days.
- Management: progressive ventilation from the 2nd–3rd week; first nutrition very diluted after one month.
Grafting (Advanced)
- Accelerates the growth of seedlings or rescues valuable material. Rootstocks: Myrtillocactus geometrizans, Trichocereus spachianus, and other vigorous Trichocereus species.
Pruning, Shaping, and Managing Growth Habit
- Descoping to induce branching at the desired height (ideal for landscaping specimens).
- Sanitation: make cuts in dry and warm conditions; apply sulfur and keep dry until callus forms.
- Renewal: segment aging columns and replant bases to rejuvenate.
Pests and Diseases
Common Pests
- Cotton mealybug (both aerial and root): inspect areoles and neck. Control: 70% isopropyl alcohol, potassium soap, and horticultural oil in rotation. For the roots: wash the root ball and transplant to clean substrate. In larger production, consider biological control (Cryptolaemus, Anagyrus).
- Spider mites: frequent in heat and low humidity conditions. Prevention: ventilation, morning showers in summer outdoors and light oils; in greenhouses, introduce Phytoseiulus persimilis.
- Thrips/scales: monitor and apply local-authorized targeted treatments.
- Slugs and snails: use physical barriers and perimeter baits.
Diseases
- Rot of neck/root due to excess moisture and cold: clean until healthy tissue, disinfect tools, apply sulfur/copper on cuts, and cure in dry conditions. Adjust watering and drainage.
- Leaf spots (anthracnose, etc.): improve aeration; use contact fungicides where authorized; avoid night wetting of the stem.
- Iron chlorosis: typical with hard water pH>7. Adjust watering pH and apply Fe-EDDHA.
Common Problems and Solutions
- Etiolation: insufficient light or excess N. Gradually increase irradiance and balance fertilization.
- Sunburn: after sudden changes to full sun. Acclimate for 2–3 weeks with shade.
- Edema: overwatering with cold substrate. Water during warm hours and improve drainage.
- Cracking: hydration spikes following prolonged drought. Stabilize watering frequency and volumes.
Annual Calendar (Northern Hemisphere; reverse for Southern Hemisphere)
- Mar–Apr: resume watering; first light fertilizations; transplanting and cutting.
- May–Aug: peak growth phase. Regular deep watering; full nutrition; weekly phytosanitary control.
- Sep: reduce N; prioritize K/Ca/Si; check supports before stormy weather.
- Oct–Nov: space out watering; prepare for dry wintering; protect from cold rains.
- Dec–Feb: dormancy; maintain almost dry; monitor for root mealybugs.
Differentiation from Related Species
- T. pachanoi: generally has less spination (0–7 short spines), greener color, and 6–8 rounder ribs. Bridgesii usually displays longer and more pronounced spines.
- T. peruvianus (E. peruviana): high variability; clones may be more glaucous and have intermediate to long spines, with areoles often spaced further apart in many cultivars.
- T. macrogonus: often has more spines (up to ~20 spines/areole, with long central spines), with a more slender growth habit in some clones.
- E. scopulicola: treated by some as closely related to lageniformis; typically has fewer spines and a smoother appearance. Differences are subtle and a matter of taxonomic debate.
Forms and Cultivars
- Monstrose/crest forms (TBMs, cristatas): slower growth and unusual morphology; highly valued in collections. They require even more mineral substrates, very careful watering, and extra protection from cold rain.
- Other cultivars of collector interest: lines with variations in spination, coloration, and vigor.
Use in Landscaping and Design
- Installation: slopes, rockeries, and xerophytic beds. Leave 80–120 cm between specimens for natural growth and branching.
- Soil: plant on raised beds/plateaus of 15–30 cm for drainage. Use spaced drip irrigation in dry/hot climates.
- Combinations: Agave, Dasylirion, Yucca, xerophytic grasses, Tephrocactus.

- Rot of neck/root due to excess moisture and cold: clean until healthy tissue, disinfect tools, apply sulfur/copper on cuts, and cure in dry conditions. Adjust watering and drainage.
- Leaf spots (anthracnose, etc.): improve aeration; use contact fungicides where authorized; avoid night wetting of the stem.
- Iron chlorosis: typical with hard water pH>7. Adjust watering pH and apply Fe-EDDHA.
Common Problems and Solutions
- Etiolation: insufficient light or excess N. Gradually increase irradiance and balance fertilization.
- Sunburn: after sudden changes to full sun. Acclimate for 2–3 weeks with shade.
- Edema: overwatering with cold substrate. Water during warm hours and improve drainage.
- Cracking: hydration spikes following prolonged drought. Stabilize watering frequency and volumes.
Annual Calendar (Northern Hemisphere; reverse for Southern Hemisphere)
- Mar–Apr: resume watering; first light fertilizations; transplanting and cutting.
- May–Aug: peak growth phase. Regular deep watering; full nutrition; weekly phytosanitary control.
- Sep: reduce N; prioritize K/Ca/Si; check supports before stormy weather.
- Oct–Nov: space out watering; prepare for dry wintering; protect from cold rains.
- Dec–Feb: dormancy; maintain almost dry; monitor for root mealybugs.
Differentiation from Related Species
- T. pachanoi: generally has less spination (0–7 short spines), greener color, and 6–8 rounder ribs. Bridgesii usually displays longer and more pronounced spines.
- T. peruvianus (E. peruviana): high variability; clones may be more glaucous and have intermediate to long spines, with areoles often spaced further apart in many cultivars.
- T. macrogonus: often has more spines (up to ~20 spines/areole, with long central spines), with a more slender growth habit in some clones.
- E. scopulicola: treated by some as closely related to lageniformis; typically has fewer spines and a smoother appearance. Differences are subtle and a matter of taxonomic debate.
Forms and Cultivars
- Monstrose/crest forms (TBMs, cristatas): slower growth and unusual morphology; highly valued in collections. They require even more mineral substrates, very careful watering, and extra protection from cold rain.
- Other cultivars of collector interest: lines with variations in spination, coloration, and vigor.
Use in Landscaping and Design
- Installation: slopes, rockeries, and xerophytic beds. Leave 80–120 cm between specimens for natural growth and branching.
- Soil: plant on raised beds/plateaus of 15–30 cm for drainage. Use spaced drip irrigation in dry/hot climates.
- Combinations: Agave, Dasylirion, Yucca, xerophytic grasses, Tephrocactus.
Technical Summary Sheet
- Origin: Bolivia (La Paz, Cochabamba, Tarija, Chuquisaca).
- Altitude: 1,000–3,300 m a.s.l.
- Height: 2–5 m in mature cultivation.
- Stem: 15–20 cm in diameter; 4–8 ribs.
- Flower: white, nocturnal, fragrant, 15–20 cm long.
- Substrate: highly draining; pH 5.8–6.5.
- Watering: deep and spaced during warm weather; almost dry in cold.
- Fertilization: low in N, high in K, with micros; 50–100 ppm N per event during the growing season.
- Zones: USDA 9a–11 (punctual tolerances below 0 °C in dry conditions and with expert management).
Best Practices for Nursery Production
- Density: beds 30–40 cm apart for initial growth in 20–25 L pots; expand in the second year.
- Fertigation: 0.8–1.2 mS/cm at peak; foliar corrections in microdoses (Fe, Zn, Mn) based on analysis.
- Hygiene: quarantine new arrivals for 3–4 weeks; disinfect beds and tools; use new substrate for each propagation.
- Clonal Selection: lines with moderate spination for retail; lines with high vigor for landscaping.
Quick FAQ
- How much light does it need? Full sun with acclimatization. Indoors only with strong lighting and good ventilation.
- Does it tolerate frost? Brief and dry frost is better above −3/−4 °C. Recommended USDA 9a+.
- How often should I water? When at least half of the substrate is dry; almost dry in winter.
- How does it reproduce? Very easy by cutting; by seed with sterile handling and heat; grafting to accelerate growth.
- Why is it turning yellow? Due to pH/hard water or iron deficiency. Adjust watering pH and apply Fe-EDDHA.
