What am I doing wrong? For the life of me I canât keep succulents alive! This is my second go with all new plans and so far one is completely rotting and the other lost half itâs thing.. Iâm watering when the app says about once every 2 weeks, they have a growth light (which I slowly got them use to.) I love the look of them but canât keep them alive!! Whyâs causing them to loose their petals? Or rot. Itâs cactus soil, pot has drainage. Any advice would be great!
