Is your Living Stones showing falling leaves? Discover 15 possible causes and how to treat them.
🔍 Possible Causes (15)
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
✓ Related symptoms:
- • Heavily infected leaves may brown completely and drop prematurely
⚡ Quick Fixes:
Remove all visibly infected leaves
Nitrogen Deficiency
Nitrogen deficiency occurs when plants lack sufficient nitrogen, an essential macronutrient needed for chlorophyll production and overall growth. This deficiency typically manifests as yellowing leaves, starting with older foliage and progressing to newer growth if left untreated.
✓ Related symptoms:
- • Premature leaf drop in severe cases
⚡ Quick Fixes:
Step 1
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.
✓ Related symptoms:
- • Dropping leaves (both old and new) that may be green, brown, or yellow
⚡ Quick Fixes:
Step 1
Heat Stress
Heat stress occurs when plants are exposed to excessively high temperatures, typically above 85-90°F (29-32°C), causing physiological damage and compromising vital processes such as photosynthesis and transpiration.
✓ Related symptoms:
- • Flower and fruit drop
- • Leaf drop (defoliation)

Step 1
Salt Buildup
Salt buildup (also called salt accumulation or fertilizer salt deposits) is an environmental condition where mineral salts accumulate in the soil over time, creating a toxic environment for plant roots. The most visible sign is a white or yellowish crusty layer on the soil surface or around pot edges.

- • Premature leaf drop
⚡ Quick Fixes:
Step 1
Poor Air Circulation
Poor air circulation is an environmental stress condition that occurs when plants lack adequate airflow around their foliage and stems. Stagnant air creates a microenvironment that promotes moisture buildup, depletes available CO2, and weakens plant defenses against fungal diseases and pests. This is especially common with densely packed indoor plants or plants placed in corners with limited ventilation.
✓ Related symptoms:
- • Leaf drop or browning at leaf tips
⚡ Quick Fixes:
Install a fan immediately
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.
✓ Related symptoms:
- • Yellowing and dropping of older leaves
⚡ Quick Fixes:
Step 1
Transplant Shock
Transplant shock is a stress response that occurs when plants are abruptly moved from one environment to another. This environmental condition affects plants during repotting, moving between indoor/outdoor locations, or transplanting from nursery pots to gardens. Root damage during the move is the primary cause, making it nearly impossible to completely avoid some degree of stress.

- • Leaf drop or premature shedding

Step 1
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.
✓ Related symptoms:
- • Leaves dropping prematurely
⚡ Quick Fixes:
Emergency unpotting
Crown Rot
Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.
✓ Related symptoms:
- • Yellowing of lower leaves that drop prematurely
⚡ Quick Fixes:
Immediate unpotting
Damping Off
Damping off is a soil-borne fungal disease that affects seeds and young seedlings, causing rotting of stem and root tissues at and below the soil line. It is caused by several fungi including Pythium, Rhizoctonia, Fusarium, and Phytophthora. The disease thrives in cold, wet conditions with poor air circulation.
✓ Related symptoms:
- • Seedlings collapse and fall over at stem base
⚡ Quick Fixes:
Immediate Discard
Bacterial Blight
Bacterial blight is a serious plant disease caused by pathogenic bacteria that enters plants through wounds or natural openings. It spreads rapidly in warm, wet conditions and can cause significant damage to leaves, stems, and flowers. The bacteria are transmitted by water splash, contaminated tools, and insects.
✓ Related symptoms:
- • Premature leaf drop
⚡ Quick Fixes:
Step 1
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.
✓ Related symptoms:
- • Leaf drop and defoliation
⚡ Quick Fixes:
Step 1
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.
✓ Related symptoms:
- • Premature leaf drop and potential plant death
⚡ Quick Fixes:
Step 1
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.
