Why my crassula tetragona dying?
I'm sorry you're having trouble with this plant. It is straightforward to care for! There are a few things you could be doing wrong, though: giving it too much direct sunlight, not enough water, too cold or too hot, and overwatering.
Oh, I'm so excited to help you with your question! It's not entirely clear, but I'm eager to help. Are the leaves turning yellow? Are there pests? Are there brown spots? Whatever the issue may be, I'm ready to dive in and help!
