Yucca Cane Decline After Moving Indoors: Black Spots and Wilting

A Yucca cane (trimmed to resemble a palm) was moved from an outdoor sunroom to indoors for winter. New growth wilted, black spots appeared, and webs were noticed. The owner clipped affected leaves but the plant declined rapidly.

Diagnosis

Root problem due to insufficient light and unchanged watering routine. Yuccas need:

Small pot with porous soil
Direct sun from an uncovered window
Soil dry 1/4 down before thorough watering
Filtered/distilled water if tap water is hard

Webs are likely not spider mites (Yuccas don't attract them). The expert offers a Yucca care article via email.
