The San Pedro cactus is native to the Andes mountains of Ecuador and Peru. The curanderos, or shamans, of Peru have used the cactus in a ritual drink since 1000 B.C. The cactus is hardier than most cacti, and can withstand a greater range of temperatures. The San Pedro cactus can be grown in temperate areas unlike many other cacti, and does well indoors. In Ohio, the winter climate would not be appropriate for the San Pedro cactus, but it can be grown indoors and brought outside in the summer.
Create your soil mix by mixing equal parts sand and compost. Measure enough pumice to equal the amount of sand and compost mixture. Blend the mixture together well.
Make sure your clay pot has a drainage hole in the bottom. Fill your pot with the soil mixture until it reaches ½ inch from the top edge of the pot.
Mix your San Pedro seeds with about ¼ cup of cactus soil mix from a nursery. Spread the seed mixture over the soil surface evenly.
Use a spray bottle to gently mist water over the surface of the soil until it is moist. Let the soil dry before watering again. Continue to keep the soil evenly moist for the first six months of growing your cactus. Avoid flooding your plants with water because this may dislodge the seed, which are very small.
Cover your pot with a plastic bag to increase the humidity around your cactus seeds. The San Pedro cactus prefers a temperature of 70 to 90 degrees F with a high humidity to germinate.
Place a full spectrum grow light over your seeds and give them 16 to 18 hours a day. Once your plants are a year old you can take them outside into direct sunlight during the summer months in Ohio.
Feed your cactus once it becomes established in the pot with a low nitrogen fertilizer such as 2-7-7 once a week. You can also use fertilizers that are especially formulated for cactus plants. Reduce watering to once a week in the summer, and once a month in the winter.
