Saving Office Plants in Very Low Light

Wrong Plants for the Location

Dragon tree (Dracaena marginata) and likely Yucca need bright indirect light. Your "very, very little light" explains decline: leaf drop, black spots.

Immediate Actions

1. Move to brightest available spot.
2. If impossible, replace with true low-light plants: ZZ plant, Dracaena 'Janet Craig', Chinese evergreen, pothos.
3. Full-spectrum bulb helps only if directly over each plant 10+ hours daily—costly and inadequate.

Air Circulation

Poor airflow worsens fungal issues (black spots). Add a small fan if possible.
