Leaf Issues

Yellowing Leaves

Symptoms: Leaves turn pale green to yellow, starting with older leaves and progressing upward. May affect entire branches in severe cases. Common Causes:

• Nitrogen deficiency from poor soil or lack of fertilizer
• Overwatering causing root oxygen deprivation
• Natural aging of older leaves in autumn

Solutions:

• Apply balanced slow-release fertilizer in spring (10-10-10)
• Check soil drainage and reduce watering frequency if soil stays wet
• Remove yellowed leaves to redirect energy to healthy growth

Prevention: Maintain consistent watering schedule and fertilize twice yearly in spring and early summer. Ensure proper drainage in planting area.

Brown/Crispy Leaves

Symptoms: Leaf edges turn brown and crispy, eventually spreading inward. Leaves may curl or become papery. Common Causes:

• Drought stress or insufficient watering
• Salt accumulation from hard water or over-fertilization
• Wind damage or extreme heat exposure

Solutions:

• Deep water weekly during dry periods, ensuring soil moisture reaches root zone
• Flush soil with clean water to remove salt buildup
• Provide wind protection or temporary shade during heat waves

Prevention: Mulch around base to retain moisture, use rainwater when possible, and avoid fertilizing during drought conditions.

Drooping/Wilting

Symptoms: Branches and leaves hang limply despite adequate soil moisture. May recover temporarily after watering. Common Causes:

• Root damage from cultivation or pests
• Vascular disease blocking water transport
• Transplant shock in newly planted specimens

Solutions:

• Check for root damage and improve soil conditions if needed
• Prune affected branches to reduce water demand
• Provide supplemental water and shade for transplant recovery

Prevention: Avoid disturbing roots during maintenance, plant at proper depth, and water deeply after transplanting.

Leaf Drop

Symptoms: Premature leaf loss during growing season, often starting with interior leaves. May leave bare branches. Common Causes:

• Stress from drought followed by heavy watering
• Fungal infections in humid conditions
• Natural response to environmental changes

Solutions:

• Maintain consistent moisture levels avoiding extremes
• Improve air circulation through selective pruning
• Apply fungicide if disease is confirmed

Prevention: Water regularly during dry spells, space plants properly for airflow, and remove fallen leaves promptly.

Growth Issues

Stunted Growth

Symptoms: Minimal new growth, shortened internodes, smaller than normal leaves and overall reduced vigor. Common Causes:

• Compacted or poor quality soil
• Competition from grass or aggressive plants
• Inadequate nutrients in soil

Solutions:

• Amend soil with compost and organic matter
• Remove competing vegetation within 2-3 feet of plant
• Apply complete fertilizer formulated for shrubs

Prevention: Prepare planting site properly with amended soil, maintain mulch ring, and fertilize annually.

Leggy/Stretching Growth

Symptoms: Long, weak stems with sparse foliage. Plant appears open and scraggly rather than full. Common Causes:

• Insufficient light causing etiolation
• Lack of pruning allowing old wood accumulation
• Over-fertilization promoting soft growth

Solutions:

• Relocate to sunnier location or remove shade sources
• Rejuvenation prune removing 1/3 of oldest stems annually
• Reduce nitrogen fertilizer and focus on balanced nutrition

Prevention: Plant in appropriate light conditions, establish regular pruning schedule, and avoid excessive fertilization.

Pest Problems

Aphids

Identification: Small, soft-bodied insects clustered on new growth and flower buds. Green, black, or white in color. Damage Signs: Curled leaves, sticky honeydew on foliage, stunted new growth, and sooty mold development. Treatment:

• Spray with strong water stream to dislodge aphids
• Apply insecticidal soap or neem oil weekly
• Release ladybugs or lacewings as biological control Prevention: Monitor new growth in spring, encourage beneficial insects, and avoid over-fertilizing with nitrogen.

Scale Insects

Identification: Small, brown or white bumps on stems and branches that don't move. May appear waxy or cottony. Damage Signs: Yellowing leaves, branch dieback, sticky honeydew, and overall decline in plant vigor. Treatment:

• Scrape off scales with soft brush or cloth
• Apply horticultural oil during dormant season
• Prune and destroy heavily infested branches Prevention: Regular inspection of stems, maintain plant health, and apply dormant oil spray preventatively.

Spider Mites

Identification: Tiny spider-like pests visible with magnification. Fine webbing on leaves and stems. Damage Signs: Stippled or bronzed leaves, fine webbing, leaf drop, and general plant decline. Treatment:

• Spray with water to reduce populations and remove webbing
• Apply miticide or insecticidal soap every 3-5 days
• Prune out severely damaged foliage Prevention: Maintain adequate humidity, avoid dusty conditions, and monitor during hot, dry weather.

Disease Issues

Powdery Mildew

Symptoms: White, powdery coating on leaves and stems. Leaves may distort or yellow beneath fungal growth. Causes: High humidity, poor air circulation, and shade create ideal conditions for fungal development. Treatment:

• Apply fungicide containing sulfur or potassium bicarbonate
• Remove infected leaves and improve air circulation
• Spray with baking soda solution (1 tbsp per gallon water) Prevention: Space plants properly, water at soil level, prune for airflow, and choose resistant varieties.

Anthracnose

Symptoms: Dark, sunken spots on leaves and stems. Leaves may develop brown patches and drop prematurely. Causes: Fungal infection spread by water splash during cool, wet weather. Treatment:

• Prune out infected branches during dry weather
• Apply copper-based fungicide in early spring
• Rake and destroy fallen leaves Prevention: Avoid overhead watering, maintain good sanitation, and apply preventive fungicides in spring.

Root Problems

Root Rot

Symptoms: Yellowing leaves, branch dieback, loose bark at base, and musty odor from soil. Identification: Roots appear brown or black instead of white, soft and mushy to touch. Treatment:

• Improve drainage immediately by amending soil
• Remove affected roots and replant in fresh soil
• Apply fungicide drench to remaining roots Prevention: Plant in well-draining soil, avoid overwatering, and ensure proper planting depth.

Root Bound

Symptoms: Slowed growth, quick wilting between waterings, roots visible at soil surface or drainage holes. Identification: Dense mat of circling roots when removed from container, little soil visible. Treatment:

• Transplant to larger container or ground
• Score root ball vertically to encourage outward growth
• Loosen and spread roots before replanting Prevention: Repot container plants every 2-3 years, choose appropriate container size, and monitor root development.

Environmental Stress

Temperature Shock

Symptoms: Sudden leaf drop, wilting despite moist soil, branch dieback after cold snaps. Causes: Rapid temperature changes, late spring frosts, or extreme winter cold without snow cover. Treatment: Prune damaged growth in spring, provide temporary protection during extreme events, water well before freeze events. Prevention: Choose appropriate planting location, mulch for root insulation, and avoid late season fertilization.

Humidity Issues

Low Humidity Symptoms: Crispy leaf edges, increased spider mite activity, poor berry development. High Humidity Symptoms: Fungal disease proliferation, soft growth susceptible to damage. Solutions: Group plants together, use drip irrigation, improve air circulation with selective pruning. Prevention: Select appropriate microclimate for planting, maintain proper plant spacing.

Light Stress

Too Much Light: Bleached leaves, sunscald on berries, wilting during hottest part of day. Too Little Light: Sparse flowering, leggy growth, reduced berry production, open growth habit. Solutions: Provide afternoon shade in hot climates, relocate to brighter location if too shaded, use reflective mulch. Prevention: Evaluate light conditions before planting, choose location with appropriate exposure for variety.
