What about succulent fertilizer? But, the right fertilizer every few months can drastically change how succulents thrive. This will occur more often in the summer, so check back every few weeks. However, it is important to repot it every one or two years to give your plants more nutrients that will promote healthy growth. Plants can survive all year. However, animals will often become dormant in summer and may not require watering except under extreme heat. If you're in an area with extreme heats, make sure that you protect your plant.
