To save a dying plant, first, identify the underlying problem, which is often improper watering, insufficient or excessive light, or pests. Then, prune dead or damaged leaves and stems, provide the appropriate amount of light, adjust your watering schedule and volume to keep the soil moist but not soggy, and ensure the plant has adequate humidity. If the plant is root-bound, repot it in fresh, well-draining soil in a slightly larger pot.  

Identify the Cause

Watering Issues: Both overwatering and underwatering are common causes of decline. Overwatering can lead to root rot, while underwatering can cause wilting. 

Light Problems: Too little light can cause pale leaves and slow growth, while too much direct sunlight can scorch leaves. 

Nutrient Deficiency: A struggling plant may need more nutrients, especially if it's in the growing season. 

Pests: Check for signs of bugs. 

Root-Bound: If the plant's roots are circling tightly in the pot, they may not have access to new soil and nutrients.
