Succulents need a lot of light to thrive. Most varieties need about 6 hours of bright light a day. Indirect, or filtered light is best. Be cautious about keeping plants in direct sunlight. Some succulents cannot handle direct light and will scorch. If you are looking to keep your plants outdoors, introduce them to direct sunlight slowly.
Although succulents can handle some drought, they do need regular watering to survive. In the Spring and Summer you may find your plants drying out more quickly. Test the soil by pushing your finger in, and only water when at least half the soil is dry to the touch. Overwatering can kill succulents, so make sure the soil is dry before watering.
Succulents only require a light feeding during the Spring and Summer. Use a half-strength succulent food once a month to keep them looking their best.
