Yucca Plant Decline After Repotting and Moving Away from Window

A large, old Yucca was repotted from a small pot to a much larger clay pot, then moved from a large window to a room near a radiator but no window. Leaves turn light green/yellow, fall easily, plant thinned out.

Mistakes

1. Overpotting: Too-large pot retains water, causing root rot. Undo repotting; return to original or similar-sized pot.
2. Insufficient light: Yuccas need full sun from the sunniest window. If size is an issue, prune instead of moving.
