Croton with Falling Leaves: Causes and Solutions
Croton variegatum
Is your Croton showing falling leaves? Discover 7 possible causes and how to treat them.
🔍 Possible Causes (7)
Low Humidity Stress
Low humidity stress occurs when indoor air becomes too dry, causing plants to lose moisture faster than they can absorb it through their roots. This is especially common during winter heating periods, near radiators and heating vents, or in air-conditioned spaces. Tropical plants are particularly susceptible to low humidity damage.

Low Light Stress
Low light stress, also known as etiolation, occurs when plants do not receive adequate light for proper growth and development. This leads to abnormal growth patterns characterized by elongated stems, pale leaves, and weakened overall structure as the plant attempts to reach toward available light sources.

Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.

Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.

Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.

Underwatering
Underwatering or drought stress is a physiological disorder that occurs when the amount of water a plant loses through transpiration exceeds the amount its roots can absorb from the soil. This leads to cellular dehydration and various visible symptoms that can compromise plant health and productivity.

- • Premature leaf drop
- • Flower or fruit drop

Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
