While removing farina doesn’t severely harm succulents, it’s best to keep it intact. Here’s why:

It’s nature’s way of ensuring these desert-dwelling plants stay pristine even in dusty environments.
Farina vs. Powdery Mildew: Spotting the Difference
It’s crucial to distinguish between healthy farina and harmful powdery mildew. Here’s how:
- Farina: Appears as an even, consistent layer across the plant’s surface
