This is good news for succulents that are still in the plastic pot. A small pot has a high evaporation rate and can hold very little water. The stems are thick and grow taller before their weight causes them to bend. They can either hang from the pot or trail along ground. Make sure you plant it in well-drained soil and a tall potter. "Old Man Cactus" (a potted cactus) is a tall cylindrical plant that's covered in modified spines. These spines resemble hair and are popular among potted cacti. These spines grow long, looking like the shaggy hair of an old man.
