ZZ Plant Brown Tips?
The common causes, and how to tell them apart.
Brown tips on a ZZ plant are usually a moisture or mineral issue rather than a disease. Very dry air and inconsistent underwatering dry the tips out, and fertiliser-salt buildup burns the edges. A white crust on the soil points to salts. Snap a photo below for an instant diagnosis and the exact fix.

The 3 causes, compared
| Cause | How to spot it | Fix |
|---|---|---|
| Low humidity / dry air | Uniform dry brown tips, worst in a very dry room | Raise humidity a little by grouping plants; the ZZ handles dry air well, so only extreme dryness shows at the tips |
| Underwatering / inconsistent water | Brown tips with some wilting and bone-dry soil | Water thoroughly when the top inch is dry and keep to a steady schedule |
| Salt / fertiliser buildup | Brown edges with a white crusty deposit on the soil or pot rim | Flush the soil with plain water until it drains freely, and feed less often |
FAQ
- Why does my low-maintenance ZZ plant have brown tips?
- Even a tough ZZ shows stress at the tips first. The usual culprits are very dry air, letting it go bone-dry too long, or a buildup of fertiliser salts in the soil.
- Should I cut the brown tips off?
- You can trim them to a natural point for looks, but the tip won't regrow. Fix the cause so new growth comes in clean.
