Over or underwatering is the most common issue for succulent growers. But there are more problems. Likewise, a tiny pot will dry out more quickly than a large one. To help contain the mess, it is a good idea to place a newspaper or drop cloth on your desk or table. They'll have less surface area from which to lose moisture. Sometimes the stem may appear soggy, and the plant can look'sick' overall. To avoid harsh conditions, you will often find them in groups within sheltered rock crevices.
