Why are my ZZ plant leaves turning yellow?
Most often it's overwatering. Plants yellow from the bottom up when they're stressed — usually water, light, or nutrients. Check the soil first: if it's soggy, you've been too generous with the watering can.
ZZ plants store water in their rhizomes, so they rot quickly in wet soil. Yellowing leaves that pull away easily usually mean the roots are drowning. Stop watering and let the soil go bone dry.
Should I cut the yellow leaves off my ZZ plant?
Yes — once a leaf is fully yellow it's not coming back, and it's draining energy your plant could spend on new growth. Snip it clean at the base with sharp scissors. A leaf that's only partly yellow can hang on a while longer while you fix the underlying issue.
How do I fix yellow leaves on my ZZ plant?
Start with the soil. Let the top inch or two dry before watering again, and make sure your pot actually drains. Then check light — a ZZ plant sitting too dark will slowly yellow. Fix one thing at a time so you know what worked.
Why are my ZZ plant stems turning yellow and falling over?
That's classic overwatering. The rhizome under that stem has rotted, so the stem yellows and goes limp. Pull it out, trim anything mushy, and repot the firm parts into dry soil.
