Succulents are about the easiest plants you can grow and require little care. In addition to providing plenty of light and well-draining soil, water them sparingly, divide when they get crowded, and protect from exposure to temperature extremes.
When in doubt, DON’T. The single most frequent cause of death of succulents is overwatering. If the soil in the container becomes too dry, soak the pot in a pail of water. After watering, be sure to drain out the excess water.
If temperatures are over 100 degrees F for an extended period, you may need to water twice a week. If they are in pots, water the plants thoroughly to soak the roots and flush out salts.
As a rule, succulents don’t mind crowding. Plants that have grown together and are crowding each other will appreciate being thinned out and given a bit more space. A reliable time of year to do this is when plants are beginning to grow, often in the spring and fall for the winter growers like Aeonium.
Succulents appreciate a top dressing of crushed granite, pea gravel, or gravel. This looks good and helps retain water.
Most succulents can tolerate temperatures down to 40 degrees F. During the winter months, protect from frost using frost cloths.
