Why is it important to take care of a succulent. Succulents don't need much fertilizer, but giving them light feedings in the spring and summer will promote growth and keep them happy. During the spring season, your plant is awake from the dormant stage and begins to experience some growth. Just be sure to keep in mind that compost is not necessary for healthy Lithop growth. Succulents are adapted to survive in areas with limited water supply. In the winter months, watering should occur far less frequently due to dormancy.
