Overwatering

Wet soil plus yellowing lower leaves points squarely at overwatering — by far the most common way to lose a yucca.

Diagnosis

Overwatering

What's happening

Yucca is a desert plant built to survive long droughts, and its thick roots rot quickly when they sit in wet soil. Waterlogged roots can't take up oxygen, so they suffocate and start to decay, and the plant sheds its oldest lower leaves first — they turn a soft, uniform yellow and droop before they drop.

How to fix it

Stop watering immediately and let the soil dry out completely. Slide the plant out of its pot and inspect the roots — firm and pale is healthy, brown and mushy is rot. Trim away any soft, rotted roots with clean scissors and repot into a gritty, fast-draining cactus or succulent mix in a pot with drainage holes. From now on, water only when the soil is dry several inches down — for most yuccas that means roughly every two to three weeks, and far less in winter.

What fixes it
