Short answer
Ficus elastica leaves droop primarily due to improper soil moisture or sudden environmental stress. The most common fix is to allow the top few inches of soil to dry out completely before watering and ensuring the plant is kept away from cold drafts or heat vents.
Drooping leaves on a Rubber Plant are a classic distress signal that the plant is struggling to regulate its internal water pressure. While some minor flagging can occur after a repotting or a move, persistent wilting is a moderate concern that usually points to a disruption in the plant's root environment or exposure to unfavorable ambient conditions.
Ficus elastica are sensitive to 'wet feet' which leads to root rot and an inability to hydrate the leaves. When roots are suffocating in saturated soil, they stop absorbing water, causing the foliage to sag and eventually drop.
Check: Check the bottom drainage holes; if the soil is dark, muddy, or smells musty, the plant is waterlogged.
Fix: Hold off on all watering until the top 2-3 inches of soil are dry, and ensure the pot has adequate drainage holes.
Rubber Plants are highly sensitive to sudden changes in temperature caused by HVAC vents, drafty windows, or doors. Even if the room temperature is generally fine, a direct blast of hot or cold air will cause the plant to shock and droop its leaves.
Check: Observe if the plant is positioned within three feet of a vent, radiator, or drafty entry door.
Fix: Relocate the plant to a spot with stable temperatures and consistent, bright, indirect light.
While they prefer to dry out, Ficus elastica will eventually wilt if left bone-dry for too long. If the entire root ball has become dehydrated, the leaves will lose their turgidity and begin to hang downward.
Check: Check if the soil has pulled away from the sides of the pot and if the leaves feel limp and thin rather than firm.
Fix: Give the plant a thorough soak until water runs through the drainage holes, ensuring the entire soil mass is moistened.
When to worry
If the leaves begin to turn yellow, develop brown mushy spots, or start dropping rapidly after drooping, the plant requires immediate repotting to address potential root rot.

Diagnose my Rubber PlantNo, misting does not address the root causes of drooping like overwatering or drafts and can encourage fungal issues on the large leaves.
If the drooping was caused by mild thirst, the leaf will typically firm up within 24 hours of watering; however, if the tissue is severely damaged by rot or cold shock, it will likely remain limp or drop.
Dust doesn't directly cause wilting, but it inhibits photosynthesis by blocking light, which weakens the plant over time and makes it more susceptible to stress.
