For example, if your succulent becomes dormant in winter, you should repot it in late autumn. The new pot can be filled with new, fresh soil. You may also want to add succulent fertilizer. You can use a mixture of pumice, clay, or pine bark to grow succulent/cactus plants in humid areas. Choose a well draining soil, or amend the soil to add drainage. This can be done by removing the soil at its base and placing it in soil that will preserve its moisture. If the breakage is severe and it appears that some segments have separated from one another, you may need to graft or replant.
