Difficulty: Moderately Easy
Step1
Decide whether you want to plant cactus indoors in pots or outdoors as part of the landscaping. Cactus will thrive in either situation.
Step2
Choose cactus from a nursery that is healthy looking and does not look withered. You will have better luck in the long run if you start off with a plump and healthy plant.
Step3
Find a spot, either indoors or outdoors, that is bright and sunny. Cactus grow best with a lot of direct sunlight.
Step4
Plant the cactus in a combination of peat, perlite and sand to get the best outcome from the plant. Water sparingly and only until soil is moist, not wet.
Step5
Keep the cactus that you are growing drier in the winter and, if outdoors, it will be safe as long as the temperature doesn't drop below 45 degrees.
Step6
Take a small cutting of an offshoot from the cactus plant to produce more plants. Start plantings in small cups filled with a sand, peat and perlite mix. Transfer to pots or the outdoors after they have grown to about three to four inches tall.
