Leaf Issues

Yellowing Leaves

Symptoms: Leaves turn yellow starting from the lower foliage, gradually progressing upward. Older leaves may drop while newer growth appears pale. Common Causes:

• Overwatering leading to poor root oxygenation
• Nitrogen deficiency or nutrient imbalance
• Natural aging of older leaves (normal if limited to bottom leaves)

Solutions:

• Check soil moisture and reduce watering frequency if soil stays wet
• Apply balanced liquid fertilizer (10-10-10) monthly during growing season
• Remove yellowed leaves to redirect energy to healthy growth

Prevention: Maintain consistent watering schedule, allowing top 2 inches of soil to dry between waterings. Feed regularly during spring and summer.

Brown/Crispy Leaves

Symptoms: Leaf edges turn brown and crispy, progressing inward. Leaves feel dry and papery to touch. Common Causes:

• Low humidity (below 40%)
• Salt buildup from fertilizers or hard water
• Excessive direct sunlight or heat stress

Solutions:

• Increase humidity with pebble trays or regular misting
• Flush soil monthly with distilled water to remove salt deposits
• Move to bright indirect light or provide afternoon shade

Prevention: Maintain 50-60% humidity, use filtered water when possible, and position in bright but filtered light.

Drooping/Wilting

Symptoms: Leaves and stems lose turgidity, appearing limp despite adequate soil moisture. New growth may curl downward. Common Causes:

• Underwatering or inconsistent watering
• Root damage from overwatering or root rot
• Temperature stress from cold drafts or heat sources

Solutions:

• Water thoroughly when top 2 inches of soil are dry
• Check roots for rot; trim affected areas and repot if necessary
• Move away from air conditioning vents, heaters, or drafty windows

Prevention: Establish regular watering routine, ensure proper drainage, and maintain stable temperatures between 60-80°F.

Leaf Drop

Symptoms: Sudden or gradual loss of leaves, often starting with older foliage. May affect entire branches. Common Causes:

• Environmental stress from relocation or seasonal changes
• Insufficient light causing energy conservation
• Spider mite or pest infestation weakening the plant

Solutions:

• Minimize plant movement and maintain stable conditions
• Gradually increase light exposure over 2 weeks
• Inspect for pests and treat with neem oil or insecticidal soap

Prevention: Acclimate plants slowly to new environments, provide consistent bright indirect light, and inspect regularly for pests.

Growth Issues

Stunted Growth

Symptoms: Little to no new growth during active growing season. Existing leaves remain small and sparse. Common Causes:

• Pot-bound roots restricting nutrient uptake
• Poor soil quality or compaction
• Insufficient light for photosynthesis

Solutions:

• Repot into container 2 inches larger with fresh, well-draining soil
• Amend soil with perlite and compost for better structure
• Move to brighter location or supplement with grow lights

Prevention: Repot every 2-3 years, use quality potting mix, and ensure 6+ hours of bright indirect light daily.

Leggy/Stretching Growth

Symptoms: Long stems with widely spaced leaves. Plant appears sparse and reaches toward light sources. Common Causes:

• Insufficient light causing etiolation
• Lack of pruning allowing uncontrolled growth
• High nitrogen fertilizer promoting vegetative growth

Solutions:

• Relocate to brighter spot or add supplemental lighting
• Prune back leggy stems by 1/3 to encourage bushier growth
• Switch to balanced fertilizer with equal NPK ratios

Prevention: Provide adequate bright indirect light, prune regularly to maintain shape, and rotate plant weekly for even growth.

Pest Problems

Spider Mites

Identification: Tiny red or brown specks on leaf undersides. Fine webbing between leaves and stems. Damage Signs: Stippled, yellowing leaves with tiny white dots. Leaves may bronze and drop. Treatment:

• Spray thoroughly with neem oil solution (2 tbsp per gallon water)
• Wipe leaves with diluted dish soap solution
• Apply miticide for severe infestations Prevention: Increase humidity above 50%, regularly mist plants, and inspect new plants before introducing to collection.

Aphids

Identification: Small, soft-bodied insects clustered on new growth and flower buds. Green, black, or white in color. Damage Signs: Curled, distorted new leaves. Sticky honeydew on foliage attracting ants. Treatment:

• Blast off with strong water spray
• Apply insecticidal soap every 3 days for 2 weeks
• Release ladybugs or lacewings for biological control Prevention: Inspect new growth weekly, maintain good air circulation, and avoid over-fertilizing with nitrogen.

Scale Insects

Identification: Brown, oval bumps attached to stems and leaf undersides. Hard or soft-bodied varieties. Damage Signs: Yellowing leaves, sticky honeydew, sooty mold growth. Stunted plant growth. Treatment:

• Scrape off manually with fingernail or soft brush
• Dab with rubbing alcohol on cotton swab
• Apply horticultural oil to suffocate remaining insects Prevention: Quarantine new plants, maintain plant vigor through proper care, and prune out heavily infested branches.

Disease Issues

Powdery Mildew

Symptoms: White, powdery coating on leaves and stems. Leaves may yellow and distort. Causes: High humidity with poor air circulation. Cool nights followed by warm days. Treatment:

• Spray with baking soda solution (1 tbsp per gallon water)
• Apply fungicide containing sulfur or potassium bicarbonate
• Remove and dispose of affected leaves Prevention: Improve air circulation, water at soil level to keep foliage dry, and space plants adequately.

Leaf Spot

Symptoms: Dark brown or black spots with yellow halos. Spots may merge and cause leaf drop. Causes: Fungal or bacterial pathogens spread by water splash. Favored by wet conditions. Treatment:

• Remove all affected leaves immediately
• Apply copper-based fungicide every 7-10 days
• Reduce watering frequency and avoid overhead watering Prevention: Water early in day, provide good air circulation, and avoid crowding plants.

Root Problems

Root Rot

Symptoms: Yellowing leaves despite moist soil. Foul smell from soil. Plant easily pulls from pot. Identification: Roots appear brown, mushy, and smell rotten instead of white and firm. Treatment:

• Remove from pot and trim all affected roots with sterile scissors
• Repot in fresh, sterile potting mix with extra perlite
• Water sparingly until new growth appears Prevention: Use well-draining soil, ensure pots have drainage holes, and never let plant sit in standing water.

Root Bound

Symptoms: Roots circling pot bottom or growing through drainage holes. Water runs through quickly without absorption. Identification: Dense mat of roots visible when removed from pot. Little soil remaining. Treatment:

• Carefully tease apart circling roots
• Repot into container 2 inches larger in diameter
• Trim up to 1/3 of root mass if severely bound Prevention: Repot every 2-3 years in spring, choose appropriate pot sizes, and monitor drainage patterns.

Environmental Stress

Temperature Shock

Symptoms: Sudden leaf drop, wilting, or browning after temperature changes. Flower buds may drop. Causes: Exposure to temperatures below 50°F or above 90°F. Rapid temperature fluctuations. Treatment: Move to stable environment, remove damaged growth, and reduce watering until recovery Prevention: Maintain temperatures between 60-80°F, protect from drafts, and acclimate gradually to outdoor conditions.

Humidity Issues

Low Humidity Symptoms: Brown leaf tips, slow growth, increased pest susceptibility High Humidity Symptoms: Fungal growth, soft rot, poor flowering Solutions: Use humidifier for low humidity, increase ventilation for high humidity Prevention: Maintain 50-60% humidity with hygrometer monitoring and appropriate adjustments.

Light Stress

Too Much Light: Bleached or scorched leaves, especially on south-facing sides Too Little Light: Pale green leaves, leggy growth, no flowering Solutions: Adjust position gradually over 1-2 weeks to prevent shock Prevention: Provide bright, indirect light or morning sun with afternoon shade.
