Growing Echinopsis Pachanoi is easy especially since this versatile cactus is very forgiving and only needs a little water and some nutrients. The best thing about San Pedros is that they don’t mind cold weather as long as the temperatures don’t drop below 15°F (-9°C). So, if you live in a temperate region, you won’t have any issues with growing San Pedro cacti outdoors.
In its natural habitat, this cactus gets a lot of natural light and its soil is more nutrient-rich than the regular cacti soil mix. If you grow this cactus in a container, you can feed the soil a little, but not too much, because it’s still a cactus.
Cacti don’t need a lot of water to grow healthy and happy, but just like any other plant, they do need some care, love, and attention. When growing Echinopsis Pachanoi indoors, make sure you place it on a well-lit window sill, preferably on the south-side, and water it more often on hot summer days.
San Pedro cacti prefer a dry environment and, like most cacti, they are very sensitive to overwatering, which is the number one cause of cacti demise. Because they naturally grow in the Andes Mountains, at high altitudes, San Pedro cacti thrive in temperate environments, so if you live in USDA Hardiness Zones 8b-10b, you can grow these beautiful ornamental plants outdoors.
When planted outdoors, San Pedro cacti will need more frequent watering in summer, and minimal watering in the cold winter months. Cold temperatures can prevent the water from evaporating, and your cacti might sit in damp soil for too long. This, in turn, can lead to root rot, which must be avoided at all costs.
A major difference between Echnopsis Pachanoi and other cacti is the fact that it requires some nutrients from time to time. You can purchase specific cacti nutrition that has high amounts of phosphorus and potassium, and low amounts of nitrogen. The ideal NPK value for cacti fertilizer is 4-7-7 and 2-7-7.
You can easily propagate Echinopsis Pachanoi cacti from offsets, which grow abundantly around the base of the mature plants. To remove the offsets safely, make a clear cut with a sharp, clean knife as close to the stem as you can. Place the fresh cutting on a piece of paper and let it dry out a little, cut it at the narrowest place possible, and let it callous for a few days. Once the cutting has calloused, you can safely place it in a container with drainage holes and well-draining soil.
If you plan on repotting your Echinopsis Pachanoi, it’s best to do it during the warm season. Before repotting, the soil should be dry to prevent damaging the roots. Remove as much soil as possible and clean any rotten or dead roots in the process. Keep an eye out for pests and diseases and treat any cuts with a fungicide. Put the plant in its new container and spread the roots as much as possible while adding fresh cacti soil mix. Let the plant rest in dry soil for a week and then start watering it lightly until the plant adjusts to its new environment.
Echinopsis have stiff spines, so you might want to wear gloves while handling these plants.
