Leaf Issues

Yellowing Leaves

Symptoms: Foliage gradually turns from silvery-white to yellow, starting with older leaves at the base and progressing upward. May be accompanied by softness or transparency in affected areas. Common Causes:

• Overwatering causing root suffocation and nutrient uptake issues
• Natural aging of older foliage, especially during dormancy
• Nitrogen deficiency from depleted soil or lack of fertilization

Solutions:

• Reduce watering frequency and ensure soil dries out completely between waterings
• Remove yellow leaves at the base to prevent fungal issues
• Apply a balanced, diluted fertilizer (1/4 strength) during active growth season

Prevention: Maintain well-draining, gritty soil mix and water only when top 2 inches are completely dry. Provide adequate drainage holes in containers.

Brown/Crispy Leaves

Symptoms: Leaf tips or edges turn brown and crispy, eventually spreading to entire leaves. Silvery foliage may develop brown patches or completely desiccate. Common Causes:

• Underwatering or extended drought stress
• Excessive direct sunlight during hot afternoons
• Low humidity combined with high temperatures

Solutions:

• Gradually increase watering if soil has been bone dry for extended periods
• Move to location with morning sun and afternoon shade during summer
• Mist around (not on) the plant during extremely dry conditions

Prevention: Establish consistent watering schedule based on seasonal needs. Provide filtered light during peak summer heat (above 85°F).

Drooping/Wilting

Symptoms: Normally upright rosettes become limp and lose their compact form. Leaves may curl downward and feel soft to touch. Common Causes:

• Root rot from overwatering or poor drainage
• Extreme heat stress above 90°F
• Transplant shock after repotting

Solutions:

• Check roots for rot; trim affected areas and repot in fresh, dry soil
• Move to cooler location with good air circulation
• Minimize watering for 1-2 weeks after transplanting to allow root recovery

Prevention: Use terracotta pots for better moisture regulation. Avoid repotting during extreme temperatures or active blooming period.

Leaf Drop

Symptoms: Healthy-looking leaves detach easily from the plant, starting from the outer rosette. May occur suddenly or gradually over several days. Common Causes:

• Temperature fluctuations below 40°F or above 90°F
• Overwatering during winter dormancy
• Natural dormancy response in late summer

Solutions:

• Maintain stable temperatures between 50-75°F when possible
• Reduce watering to once monthly during dormancy
• Accept natural leaf drop during dormancy; new growth will emerge in spring

Prevention: Gradually acclimate plant to seasonal temperature changes. Mark calendar for dormancy period (July-September) to adjust care routine.

Growth Issues

Stunted Growth

Symptoms: Plant remains same size for months, produces few new leaves, or rosettes stay abnormally small compared to typical 6-inch spread. Common Causes:

• Compacted or depleted soil lacking nutrients
• Insufficient light (less than 4 hours direct sun)
• Root-bound condition in too-small container

Solutions:

• Refresh top 2 inches of soil with fresh cactus/succulent mix
• Gradually increase light exposure to 6+ hours daily
• Repot into container 2 inches wider with fresh, gritty soil

Prevention: Annual soil refresh in spring, regular fertilization during growing season, and biennial repotting maintain healthy growth rate.

Leggy/Stretching Growth

Symptoms: Rosettes lose compact form, stems elongate between leaves, and plant reaches toward light source. Silver coloration may fade. Common Causes:

• Insufficient light causing etiolation
• Overwatering combined with low light
• Growing in shade or exclusively under grow lights

Solutions:

• Gradually move to brighter location with direct morning sun
• Prune stretched portions and propagate healthy rosettes
• Reduce watering until compact growth resumes

Prevention: Rotate plant weekly for even light exposure. Provide minimum 6 hours direct sunlight or supplement with full-spectrum grow lights.

Pest Problems

Aphids

Identification: Small green, white, or black insects clustering on new growth and flower buds. Often accompanied by sticky honeydew residue. Damage Signs: Distorted new growth, yellowing leaves, stunted flowers, and sooty mold on honeydew deposits. Treatment:

• Spray with insecticidal soap solution weekly until gone
• Release ladybugs or lacewings for biological control
• Wipe off with cotton swab dipped in rubbing alcohol Prevention: Regular inspection of new growth, maintain good air circulation, and avoid over-fertilizing which attracts aphids.

Spider Mites

Identification: Microscopic pests creating fine webbing on undersides of leaves. Leaves develop tiny yellow or white speckles. Damage Signs: Silvery leaves turn bronze or yellow, fine webbing visible in leaf joints, overall plant decline. Treatment:

• Spray forcefully with water to dislodge mites and webs
• Apply neem oil or miticide every 3 days for 2 weeks
• Isolate infected plant to prevent spread Prevention: Increase humidity around plant, regular leaf cleaning, and quarantine new plants for 2 weeks before introducing to collection.

Mealybugs

Identification: White, cottony masses in leaf joints and along stems. Slow-moving insects covered in waxy secretion. Damage Signs: Yellowing leaves, sticky honeydew, stunted growth, and presence of ants farming the mealybugs. Treatment:

• Dab individual bugs with Q-tip soaked in 70% isopropyl alcohol
• Apply systemic insecticide for severe infestations
• Remove heavily infested plant parts Prevention: Inspect new plants thoroughly, maintain proper spacing between plants, and avoid overwatering which creates favorable conditions.

Disease Issues

Root Rot

Symptoms: Plant wilts despite moist soil, leaves yellow and drop, foul smell from soil, and black or mushy roots visible. Causes: Overwatering, poor drainage, contaminated soil, or fungal pathogens like Pythium or Phytophthora. Treatment:

• Remove from pot and trim all affected roots with sterile scissors
• Dust remaining roots with fungicide or cinnamon
• Repot in completely fresh, sterile, well-draining soil Prevention: Water only when soil is dry, ensure drainage holes are clear, and use pots with adequate drainage. Avoid water on crown.

Powdery Mildew

Symptoms: White, powdery coating on leaves and stems, particularly in areas with poor air circulation. Leaves may curl or distort. Causes: High humidity combined with poor air circulation, overhead watering, or infected nearby plants. Treatment:

• Remove affected leaves and dispose in trash (not compost)
• Apply fungicide containing sulfur or potassium bicarbonate
• Improve air circulation with fan or spacing Prevention: Water at soil level only, maintain spacing between plants, and provide adequate ventilation. Avoid overhead watering.

Root Problems

Root Rot

Symptoms: Soft, mushy leaves despite dry soil surface, plant easily lifts from soil, and roots appear black, brown, or mushy when examined. Identification: Healthy roots are white or light tan and firm. Rotted roots are dark, soft, and may smell sour or musty. Treatment:

• Remove all soil and rinse roots under cool water
• Cut away all damaged roots with sterilized scissors
• Let roots dry for 24 hours before repotting in fresh soil Prevention: Use fast-draining soil mix (50% perlite/pumice), water sparingly during dormancy, and ensure pots have multiple drainage holes.

Root Bound

Symptoms: Roots circle the pot bottom, emerge from drainage holes, or create dense mat preventing water absorption. Growth slows significantly. Identification: When removed from pot, roots form solid mass matching pot shape with little visible soil. Treatment:

• Gently tease apart root ball or make vertical cuts
• Repot in container 2 inches larger with fresh soil
• Water sparingly for 2 weeks while roots establish Prevention: Repot every 2-3 years in spring, choose appropriate pot size (not too large), and monitor for roots emerging from drainage holes.

Environmental Stress

Temperature Shock

Symptoms: Sudden leaf drop, wilting, or discoloration after exposure to extreme temperatures. Flowers may abort or fail to open. Causes: Rapid temperature changes exceeding 20°F, exposure to frost, or temperatures above 95°F without acclimation. Treatment: Move to stable environment with temperatures between 60-75°F. Remove damaged portions and reduce watering until recovery signs appear. Prevention: Gradually acclimate to seasonal changes over 1-2 weeks. Bring indoors when temperatures drop below 40°F or exceed 90°F.

Humidity Issues

Low Humidity Symptoms: Crispy leaf edges, slow growth, increased susceptibility to spider mites, and failure to bloom properly. High Humidity Symptoms: Fungal issues, soft rot, and reduced silvery leaf coloration. Solutions: Use pebble trays for low humidity, increase air circulation for high humidity, and maintain 40-50% relative humidity. Prevention: Monitor humidity levels with hygrometer, adjust based on season, and provide appropriate ventilation for your climate.

Light Stress

Too Much Light: Bleached or scorched leaves, especially on south-facing sides. White/silver leaves may turn yellow or brown. Too Little Light: Etiolated growth, loss of compact form, reduced flowering, and fading of silvery leaf color. Solutions: Gradually adjust light exposure over 2 weeks. Provide shade cloth during intense summer sun or supplement with grow lights in winter. Prevention: Position in bright location with morning sun and afternoon shade. Monitor for seasonal sun angle changes.
