Leaf Issues

Yellowing Leaves

Symptoms: Leaves turn pale yellow or light green, starting with older foliage at the base of the plant. Yellow discoloration may spread upward if left untreated. Common Causes:

• Overwatering leading to poor root aeration
• Nitrogen deficiency in the soil
• Natural leaf aging in autumn or winter

Solutions:

• Reduce watering frequency and ensure proper drainage
• Apply a balanced fertilizer (10-10-10) in early spring
• Remove yellowed leaves to redirect energy to healthy growth

Prevention: Maintain consistent watering schedule, allowing soil to dry partially between waterings. Feed annually in spring with organic compost or slow-release fertilizer.

Brown/Crispy Leaves

Symptoms: Leaf edges turn brown and crispy, progressing inward. Leaves may curl or become brittle to touch. Common Causes:

• Drought stress or underwatering
• Excessive direct sunlight in hot climates
• Salt buildup from hard water or overfertilization

Solutions:

• Increase watering frequency during hot, dry periods
• Provide partial shade during peak afternoon sun
• Flush soil with clean water to remove salt deposits

Prevention: Mulch around base to retain moisture. Use rainwater or filtered water when possible. Position in partial shade in hot regions.

Drooping/Wilting

Symptoms: Branches and leaves lose rigidity, appearing limp despite adequate soil moisture. May occur suddenly or gradually. Common Causes:

• Root damage from overwatering or root rot
• Extreme temperature fluctuations
• Transplant shock after moving

Solutions:

• Check roots for rot and prune damaged sections
• Stabilize temperature by providing protection from extremes
• Water deeply after transplanting and provide temporary shade

Prevention: Plant in well-draining soil. Protect from sudden temperature changes. Transplant during dormant season for minimal stress.

Leaf Drop

Symptoms: Premature loss of green leaves during growing season. May affect entire branches or be scattered throughout plant. Common Causes:

• Environmental stress from drought or overwatering
• Pest infestation weakening the plant
• Fungal diseases affecting leaf attachment

Solutions:

• Adjust watering to maintain consistent soil moisture
• Inspect for pests and treat accordingly
• Apply fungicide if disease is suspected

Prevention: Maintain proper plant spacing for air circulation. Water at soil level to keep foliage dry. Regular monitoring for early pest detection.

Growth Issues

Stunted Growth

Symptoms: Plant fails to achieve expected size, produces smaller leaves and fewer berries. Overall vigor appears reduced. Common Causes:

• Poor soil nutrition or pH imbalance
• Competition from nearby plants or weeds
• Insufficient sunlight reaching the plant

Solutions:

• Test soil pH and amend to achieve 6.0-7.5 range
• Clear competing vegetation within 2-3 feet
• Prune overhead branches to increase light exposure

Prevention: Prepare planting site with organic matter. Maintain weed-free zone around plant. Choose appropriate planting location with adequate light.

Leggy/Stretching Growth

Symptoms: Long, weak stems with sparse foliage. Plant appears stretched and may require support to remain upright. Common Causes:

• Insufficient light causing etiolation
• Overfertilization promoting rapid, weak growth
• Lack of proper pruning

Solutions:

• Relocate to brighter location or thin overhead canopy
• Reduce fertilizer application, especially nitrogen
• Prune back leggy growth in late winter to encourage bushier form

Prevention: Plant in location receiving 4-6 hours of direct sunlight. Prune annually to maintain shape. Use balanced fertilizer sparingly.

Pest Problems

Aphids

Identification: Small, soft-bodied insects in green, black, or white colors clustering on new growth and undersides of leaves Damage Signs: Curled, distorted leaves; sticky honeydew on foliage; sooty mold growth Treatment:

• Spray with strong water stream to dislodge aphids
• Apply insecticidal soap or neem oil weekly
• Release ladybugs or lacewings for biological control Prevention: Encourage beneficial insects with companion planting. Avoid over-fertilizing which promotes soft, susceptible growth.

Spider Mites

Identification: Tiny red or yellow specks on leaves; fine webbing on undersides of foliage Damage Signs: Stippled, yellowing leaves; bronze discoloration; premature leaf drop Treatment:

• Increase humidity around plant with regular misting
• Apply miticide or horticultural oil
• Remove heavily infested leaves and dispose properly Prevention: Maintain adequate moisture levels. Rinse foliage periodically to remove dust. Monitor during hot, dry weather.

Scale Insects

Identification: Brown or white oval bumps attached to stems and leaves; immobile appearance Damage Signs: Yellowing leaves, stunted growth, sticky honeydew deposits Treatment:

• Scrape off scales manually with fingernail or soft brush
• Apply rubbing alcohol directly to scales with cotton swab
• Systemic insecticide for severe infestations Prevention: Inspect new plants before introducing to garden. Prune out infested branches promptly. Maintain plant vigor through proper care.

Disease Issues

Powdery Mildew

Symptoms: White, powdery coating on leaves and stems, especially in shaded areas Causes: High humidity combined with poor air circulation; overcrowded plantings Treatment:

• Apply fungicide containing sulfur or potassium bicarbonate
• Remove affected leaves and improve air circulation
• Spray with milk solution (1:9 ratio with water) weekly Prevention: Space plants adequately for airflow. Water at soil level. Choose resistant cultivars when available.

Anthracnose

Symptoms: Dark, sunken lesions on leaves and berries; premature fruit drop Causes: Fungal infection favored by wet conditions and moderate temperatures Treatment:

• Prune out infected branches during dry weather
• Apply copper-based fungicide in early spring
• Destroy fallen leaves and fruit to reduce spore sources Prevention: Avoid overhead watering. Maintain good sanitation practices. Apply preventive fungicide during susceptible periods.

Root Problems

Root Rot

Symptoms: Yellowing foliage despite moist soil; wilting that doesn't respond to watering; dark, mushy roots Identification: Carefully dig around base to examine roots; healthy roots are white and firm Treatment:

• Remove plant from soil and trim all affected roots
• Replant in fresh, well-draining soil
• Reduce watering frequency and improve drainage Prevention: Plant in raised beds or amend heavy soils with organic matter. Never allow standing water around roots.

Root Bound

Symptoms: Slow growth despite proper care; roots circling container or emerging from drainage holes Identification: Roots visible at soil surface; plant easily lifts from container showing dense root mass Treatment:

• Transplant to larger container or ground location
• Gently tease apart circling roots before replanting
• Water thoroughly after transplanting Prevention: Repot container plants every 2-3 years. Choose appropriately sized containers. Monitor root growth regularly.

Environmental Stress

Temperature Shock

Symptoms: Sudden leaf drop, wilting, or browning after temperature extremes Causes: Rapid temperature changes, unexpected frost, or extreme heat waves Treatment: Provide temporary protection with frost cloth or shade cloth; water deeply during recovery Prevention: Gradually acclimate plants to outdoor conditions. Mulch to insulate roots. Choose planting sites with protection from extreme conditions.

Humidity Issues

Low Humidity Symptoms: Crispy leaf edges, increased spider mite susceptibility High Humidity Symptoms: Fungal growth, soft stem rot Solutions: Group plants together to increase humidity; use pebble trays; ensure adequate spacing for air circulation Prevention: Monitor humidity levels seasonally. Adjust plant placement and care routines accordingly.

Light Stress

Too Much Light: Bleached or scorched leaves, especially on south-facing sides Too Little Light: Sparse foliage, poor flowering and fruiting, elongated stems Solutions: Provide shade cloth during intense sun; relocate to brighter location if too shaded Prevention: Research specific light requirements before planting. Observe light patterns throughout seasons before choosing permanent location.
