All the information you need to keep your hardy succulents healthy and beautiful. With the proper care and minimal effort, hardy succulents will bring your garden to life for many years to come.
Hardy succulents, unlike tender succulents, thrive in outdoor settings where they can receive full or partial daylight. Low-light levels during the growing season cause the plants to become pale and gangly. Cloudy days during the winter or dormant season are to be expected and do not negatively effect succulent growth.
We highly recommend you keep your hardy succulents outdoors, however if you do decide to keep them inside it is very important they be placed next to a window that receives a lot of light throughout the day.
Like any other plant, hardy succulents need to be watered periodically to grow and thrive. Press your finger a knuckle deep into the soil to feel for moisture. When their containing soil is dry, these plants should be watered thoroughly. The soil should then be allowed to dry completely before watering again. The frequency of watering depends on light and temperature levels and the porosity of the container. High temperature and light levels will cause the water to evaporate more rapidly from the soil, requiring more frequent watering. Glazed or plastic containers hold moisture longer than clay containers and will reduce the frequency of watering. Over watering can cause the roots to rot and will eventually kill the plant.
Hardy succulents should be fertilized throughout spring, summer and fall with a low nitrogen, water-soluble fertilizer such as Miracle-Gro or Shultz (10-15-10). This will promote vibrant colors and healthy growth through the growing season. A sign of over fertilization with nitrogen is the loss of the plant's characteristic color during the growing season.
Hardy succulents will grow and reproduce indefinitely. Sedum grow rapidly and will need to be trimmed back as it becomes semi-dormant in the winter or if it begins over-taking neighboring plants. Sempervivum rosettes die after blooming and will need to be removed. All plants you have removed to prevent crowding can be replanted in other containers or used in other landscaping projects.
