The best way to bring this piece of outdoor desert life indoors is to propagate the plant through cuttings or by seed. To propagate by cuttings, sever a few pads from the plant and let them dry on the counter, allowing the wounds to heal. Next, place the butt end of the prickly pear in a pot with dry soil and refrain from watering (to avoid rot) until you witness growth. (This technique can be used for other succulents as well, like jade plants and aloe.) To propagate by seed, rinse the pulp from the seeds, make sure they’re thoroughly dry, and then sprinkle them into a pot of moist (not wet) well-drained soil. Lightly cover the seeds with a thin layer of soil or sand, and then dress the pot in transparent plastic wrap and place it in a warm, well-lit area of your home. Then be patient—seed germination can take several weeks or months.When your prickly pear becomes root-bound or is much too big for its home, only then consider repotting. To do so, first, make sure the soil is dry. Then, shimmy the plant away from the pot by grabbing it at its base and knocking away the old soil. After treating any wounds with a fungicide, place the prickly pear into a larger pot and backfill it with well-draining potting soil. As with new succulent cuttings, don't water your repotted prickly pear right away. Allow it to reintegrate its roots first.
