What about succulent fertilizer? However, the right fertilizer used every few months can dramatically change how well your succulents thrive. This will happen more often in summer so keep checking your plants every day. It is recommended that you repot your plant every year, or at least once every two years. This will provide nutrients to encourage healthy growth. Even though plants can be grown all year, animals tend to go dormant in the summer months. They don't need water except for extreme heat. You should protect your plant if you are in an area that experiences extreme heats.
