Sow,
plant, or repot in
spring or fall when the temperature is 15 to 20 ℃ . Keep air humidity high when seeding. Use plastic film to cover the soil and remove it after the seeds germinate.
Use permeable clay flowerpots for potted
plants. Too large a flowerpot accumulates water easily, while too small a flowerpot limits the development of roots. Before planting, expose soil to blazing sunlight and disinfect to kill pathogens.
If planted in the garden,
blue cereus prefers
an area with full sun and loose soil. Remove all weeds and replace the soil if needed to ensure good water permeability and avoid root rot. Wear gloves or use tongs when planting to prevent your fingers from getting pricked. You can also wrap the
plant in a towel to help you move it.
