This plant is a succulant and because of that, it can withstand drought very well. Also the String of pearls loves hanging on a spot with lots of light. When the ‘pearl’ is big and shiny, the plant has enough moisture. When the ‘pearl’ is shriveled, it needs some water. However, be careful with too much water, when it gets too wet, it will shrivel as well because it will start to rot. So give minimal water and nutrition.
