If you mean a peace lily , the best way to perk it up is to give it bright, indirect light, water it thoroughly when the top inch of soil feels dry, and make sure it isn’t sitting in cold air or a rootbound pot.

Quick Scoop

A peace lily usually looks droopy from one of a few simple issues: too little light, inconsistent watering, cold temperatures, or a pot that’s gotten crowded with roots.

The fastest “reset” is to check the soil first, then move it to gentler light and adjust watering from there.

What to do

  1. Water it well if the soil is dry. Peace lilies need consistent watering, and stress from drying out can stop them from thriving.
  1. Move it to bright, indirect light. They can survive in low light, but they do better and bloom more with steadier light.
  1. Keep it away from cold spots. Temperatures below 50 degrees Fahrenheit can interfere with blooming and overall health.
  1. Check the pot size. If it’s rootbound, repotting into a slightly larger container can help it recover.
  1. Feed lightly in spring or summer. A little fertilizer once or twice a year can help if the plant is otherwise healthy.

Signs it needs help

  • Leaves are limp but the soil is dry: likely needs water.
  • Leaves are green but it never blooms: likely needs more indirect light.
  • It keeps declining even with water: check for rootbound growth or poor conditions.

One simple example

A common rescue routine is: water deeply, let excess drain, place the plant near a bright window with filtered light, and leave it alone for a few days so it can recover.

TL;DR

For a peace lily, the main fix is consistent care : bright indirect light, proper watering, no cold drafts, and repotting if it’s crowded.
