Care Guide Generation

1. Light Guide

Provide specific light recommendations based on plant type:

High Light Plants (Full Sun)

• Need 6+ hours of direct sunlight daily
• Best placement: South-facing balcony, unobstructed window
• Indoor suggestion: Use full-spectrum grow lights
• Examples: Succulents, cacti, roses, bougainvillea

Medium Light Plants (Part Sun)

• Need 3-6 hours of indirect light daily
• Best placement: East or west-facing windows, bright rooms
• Indoor suggestion: Avoid strong direct sunlight
• Examples: Jasmine, olive, pothos

Low Light Plants (Shade)

• Need 1-3 hours of weak or indirect light daily
• Best placement: North-facing windows, bright indoor areas
• Indoor suggestion: Avoid direct sunlight, use curtains
• Examples: Monstera, ferns, peace lily

2. Watering Guide

Basic Principles

• Follow "soak and dry" method: Water when soil surface is dry, water thoroughly
• Finger test: Insert finger 2-3 cm into soil, water if dry
• Visual check: Water when soil color becomes pale

Seasonal Adjustments

Season	Frequency	Best Time	Notes
Spring	Every 2-3 days	9-11 AM	Growth season, water moderately more
Summer	Daily or every 2 days	Morning or evening	Avoid midday watering
Fall	Every 3-5 days	Morning	Gradually reduce watering
Winter	Every 7-14 days	Midday	Keep soil slightly dry

Special Watering Methods

• Bottom watering: For small pots and succulents, soak pot in water for 10-30 minutes
• Misting: For tropical plants and humidity-loving plants

Water Quality

• Best: Rainwater, river water, pond water
• Second choice: Settled tap water (24 hours to let chlorine evaporate)
• Avoid: Dishwashing water, laundry water, water with detergents

3. Soil Guide

General Mix

• Peat moss 40% + Perlite 30% + Vermiculite 20% + Organic fertilizer 10%
• Suitable for most indoor plants

Special Plant Soils

Plant Type	Soil Mix	Drainage
Succulents	70% gritty mix + 30% peat	Must drain well
Orchids	60% bark + 30% moss + 10% perlite	Airy is key
Carnivorous plants	100% pure moss or peat	High water retention
Vines	50% leaf mold + 30% garden soil + 20% sand	Keep moist

Soil pH

• Most plants prefer pH 6.0-7.0 (slightly acidic to neutral)
• Acid-loving plants (azaleas, camellias) need pH 5.0-6.0
• Cacti tolerate alkaline soil

4. Temperature Guide

Temperature Ranges

Type	Cold Tolerance	Ideal Range	Max Tolerance
Hardy	Above -20°C	15-25°C	35°C
Semi-hardy	Above -5°C	15-25°C	30°C
Tender	Above 10°C	18-28°C	30°C

Seasonal Management

• Winter: Tropical plants need above 10°C, avoid cold drafts
• Summer: Increase ventilation in high temperatures, provide shade
• Day/night temperature difference: Some plants need this for healthy growth

5. Fertilization Guide

Fertilization Principles

• Light and frequent: Dilute concentration, don't over-fertilize
• More during growth, stop during dormancy
• Add base fertilizer during repotting, supplement regularly otherwise

Fertilizer Types

Element	Promotes	Deficiency Symptoms	Examples
Nitrogen (N)	Leaf growth	Pale leaves, yellow old leaves	Foliage plants
Phosphorus (P)	Roots & flowering	Slow growth, no flowers	Flowering plants
Potassium (K)	Disease & cold resistance	Leaf edge browning	All plants

Fertilization Schedule

• Growing season (spring/summer): Every 2 weeks
• Dormancy (winter): Stop fertilizing
• Foliage plants: Nitrogen-focused
• Flowering plants: Nitrogen during growth, phosphorus-potassium during budding

Common Problem Diagnosis

1. Yellow Leaves

Cause Analysis

Symptom	Possible Cause	Solution
Old leaves yellowing and dropping	Natural aging or nitrogen deficiency	Normal, can supplement nitrogen
New leaves turning yellow	Iron deficiency or soil alkalization	Apply iron sulfate or change to acidic soil
Interveinal chlorosis	Magnesium deficiency	Apply magnesium sulfate
Leaf edges turning yellow	Over or under watering	Adjust watering frequency
Whole plant turning yellow	Insufficient light or waterlogging	Increase light, control water

2. Wilting Leaves

Cause Analysis

Symptom	Possible Cause	Solution
Morning wilting	Normal transpiration	No action needed
Afternoon wilting	Water deficiency	Water promptly
Persistent wilting	Root rot from waterlogging	Control water, increase ventilation, repot if severe
New leaves wilting	Over-fertilization	Flush with large amount of water

3. Spots on Leaves

Cause Analysis

Symptom	Possible Cause	Solution
Brown spots	Sunburn	Move to shaded area
Black spots	Disease or waterlogging	Control water, apply fungicide
White spots	Pest damage or chemical burn	Check for pests, rinse leaves
Yellow halos	Fungal infection	Isolate affected plant, apply fungicide

4. Leggy Growth (Stretching)

Cause Analysis

• Insufficient light
• Too much nitrogen fertilizer
• Overwatering

Solutions

• Increase light duration or intensity
• Reduce nitrogen fertilizer
• Control watering frequency
• Prune stretched portions

5. Not Flowering

Cause Analysis

Cause	Solution
Insufficient light	Increase light
Too much nitrogen	Reduce nitrogen, increase phosphorus-potassium
Not yet mature	Be patient
Temperature unsuitable	Adjust to suitable range
Improper pruning	Prune correctly to promote flowering buds

2. Avoid immediate watering or sun exposure
3. Remove frost-damaged leaves
4. Keep soil slightly dry during recovery

4. Fertilizer Burn Emergency

1. Flush immediately with large amount of water
2. Repeat 2-3 times to dilute fertilizer
3. Place in ventilated area to dry
4. Reduce or pause fertilization afterward

5. Repotting Guide

When to Repot

• Best time: Before spring growth
• Roots growing out of drainage holes
• Water drains through quickly after watering
• Growth has noticeably slowed

Repotting Steps

1. Stop watering 2-3 days in advance
2. Gently tap pot sides to loosen, remove plant
3. Remove about one-third of old soil
4. Trim rotten and old roots
