Trichocereus bridgesii, also known as Echinopsis lageniformis or Bolivian Torch cactus, is a fast-growing columnar cactus native to Bolivia. It has long, sharp spines and produces large, fragrant white flowers that open at night. Trichocereus bridgesii is popular among cactus enthusiasts and collectors for its unique shape, rapid growth and ease of cultivation. In this guide, we will show you how to grow Trichocereus bridgesii from seeds or cuttings, and how to care for this amazing cactus.
Growing Trichocereus Bridgesii from Seeds
Bolivian Torch seeds are easy to germinate if you provide them with the right conditions. Here are the steps to follow:
- Fill a seed-starting container with a well-draining cactus mix. You can make your own by combining one part sharp sand, one part organic matter and two parts white pumice. Alternatively, you can use a commercial cactus mix and add some perlite or vermiculite to improve drainage.
- Sprinkle the seeds evenly on the surface of the mix. Do not cover them with soil, as they need light to germinate.
- Mist the seeds lightly with a spray bottle. Avoid watering too much or too forcefully, as this can wash away or damage the seeds.
- Cover the container with clear plastic wrap or a glass lid to create a humid environment. Place it in a warm and bright spot, but not in direct sunlight. The ideal temperature range is between 70 and 90 degrees Fahrenheit (21 and 32 degrees Celsius).
- Check the container daily and mist the seeds if the soil looks dry. You should see signs of germination within one to five weeks, depending on the freshness and quality of the seeds.
- Once the seeds have sprouted, remove the plastic wrap or lid and place the container under a grow light or in a bright windowsill. Keep the soil moist but not soggy, and water every three to five days.
- Fertilize the seedlings once a month with a diluted liquid fertilizer (5-5-5 or similar) during their active growing season (spring and summer).
- Allow the seedlings to grow in their original container for one or two years, until they are big enough to transplant into individual pots.
Growing Trichocereus Bridgesii from Cuttings
Another way to propagate Trichocereus bridgesii is by taking stem cuttings from a healthy plant. This method is faster and easier than growing from seeds, but you will need access to an established plant. Here are the steps to follow:
- Choose a healthy and mature stem that is at least 6 inches (15 cm) long. Cut it off with a sharp and sterilized knife at an angle, making sure to avoid damaging the rest of the plant.
- Let the cutting dry for a few days in a shaded and well-ventilated area, until a callus forms over the cut end. This will prevent rotting and infection.
- Prepare a pot with a well-draining cactus mix, as described above. Make a hole in the center of the soil and insert the cutting about 2 inches (5 cm) deep. Firmly press the soil around it to support it.
- Place the pot in a bright spot, but not in direct sunlight. Water sparingly, only when the soil feels dry to the touch. Do not fertilize until new growth appears.
- After a few weeks, you should see signs of rooting and new growth. You can then move the pot to a sunnier location and resume normal watering and fertilizing.
Caring for Trichocereus Bridgesii
Trichocereus bridgesii is an easy-to-care-for cactus that can thrive indoors or outdoors, as long as you provide it with enough light, water and nutrients. Here are some tips for keeping your Bolivian Torch cactus happy and healthy:
- Light: Bolivian Torch loves full sun and can tolerate high temperatures. However, if you live in an area with very hot summers, you may want to protect your cactus from sunburn by placing it in light shade during the hottest hours of the day.
- Water: Echinopsis Lageniformis has a high water demand compared to other cacti, especially during its active growing season (spring and summer). Water deeply and thoroughly whenever the soil feels dry to the touch, and let it drain completely before watering again. Reduce watering in fall and winter, and stop completely during dormancy (when no new growth is visible).
- Soil: Trichocereus bridgesii needs a well-draining and aerated soil that can prevent root rot and fungal diseases. Use a cactus mix as described above, or add some coarse sand, pumice, perlite or vermiculite to a regular potting soil. Repot your cactus every two to three years, or when it outgrows its container.
- Fertilizer: Trichocereus bridgesii benefits from regular feeding during its active growing season (spring and summer). Use a balanced liquid fertilizer (5-5-5 or similar) diluted to half strength, and apply it once a month. Do not fertilize in fall and winter, as this can cause excessive and weak growth.
- Pruning: Trichocereus bridgesii does not require much pruning, except for removing dead or damaged stems. You can also prune your cactus to shape it or to propagate it by cuttings, as described above.
- Pests and diseases: Trichocereus bridgesii is relatively resistant to pests and diseases, but it can still be affected by mealybugs, scale insects, spider mites, root rot and fungal infections. Inspect your cactus regularly and treat any problem as soon as possible. Use a cotton swab dipped in alcohol to remove mealybugs and scale insects, or spray with insecticidal soap or neem oil. For spider mites, use a strong jet of water to dislodge them, or spray with miticide. For root rot and fungal infections, cut off the affected parts and treat with fungicide. Avoid overwatering and improve drainage and ventilation.
Conclusion
Trichocereus bridgesii is a stunning cactus that can add beauty and interest to your home or garden. It is easy to grow from seeds or cuttings, and it requires minimal care once established. With enough light, water and nutrients, your Bolivian Torch cactus will reward you with spectacular growth and blooms.
