Temperature & Mild

After the main year, San Pedro thrives in direct sunlight, while seedlings may suffer sunburn in direct sunlight.

Overall, Trichocereus pachanoi thrives well in light shade throughout the hot summer months.

You should gradually expose a plant that has spent the winter indoors to direct sunlight, since they may become sunburned if transplanted directly.

Crops growing indoors will require additional illumination from develop lamps.

A healthy San Pedro can withstand temperatures as low as 50° Fahrenheit (10° C) with the rare transitory dip as low as 15.8° Fahrenheit (-9° C).

This resilience to cold can also be increased by utilizing Valerian flower extract.

After one year, seedlings can be securely moved to pots.

Grooming and Maintenance

 

  • Trichocereus pachanoi can be trimmed for grafting or pupping as well.
  • Because larger crops grow faster, you’ll need to snip 12″ inches or more.
  • For a healthy plant, no other upkeep is required.

  • A bottle with sprigs
  • Seeds that are less than ten years old (inside one yr are probably the most viable)

Planting the Seed

  • Stage the soil and gently push it down to provide a stable foundation for the seedlings.
  • Sprinkle the seeds over the soil and let them to settle on top.
  • Mist the soil and canopy lightly with water and cover with lids or plastic wrap.
  • Place the containers in a sunny location where they will not be exposed to direct sunlight.
  • You might alternatively use an LED light rated at 150 watts or more.
  • More about increase in artificial light.
  • The temperature should be kept between 77° and 86° Fahrenheit (25° – 30° Celsius).
  • Seeds should germinate in two to three weeks.
  • A seed that does not germinate in 6 weeks or shows signs of white mould on the seed itself is likely to die.
  • Open the cover and let the dirt dry before starting over.

If you find signs of fungus gnats, you should also open the lid to allow them to dry.

Mold indicators in the jar should be washed away using the spray bottle, and the jar should be allowed to dry before reclosing.

Beware: the market is flooded with low-quality seeds.

When planning to self-germinate, you need check the seed’s age.

The younger they are, the greater their chances of successful germination.

NOTE: Vegetation grows from offsets.
