South-Facing Windows (Best Light)

Light: 6-8+ hours direct sun

Best for:

• Tomatoes (dwarf varieties)

• Microgreens (with longer growing time)
• Pothos, snake plant (ornamental, air-purifying)

Solution: Supplement with grow lights

Container Selection for Windowsills

Size Considerations

• Windowsill width: Measure before buying pots
• Stability: Wider base prevents tipping
• Weight: Consider when watered (safety)
• Drainage: Saucers mandatory to protect sills

Best Container Types

• Plastic pots: Lightweight, affordable, retain moisture
• Ceramic with saucers: Decorative, stable, heavier
• Self-watering pots: Reduce watering frequency
• Rectangular planters: Maximize windowsill space
• Hanging planters: Save sill space (if hooks available)

Drainage Essentials

• Drainage holes mandatory
• Saucers to catch water (protect windowsills)
• Elevate pots slightly for air circulation
• Empty saucers after watering

Potting Mix for Indoor Plants

Basic Indoor Mix

• 50% coco peat (lightweight, clean)
• 30% vermicompost
• 20% perlite or coarse sand

Why Not Garden Soil Indoors?

• Heavy and messy
• May contain pests or diseases
• Poor drainage in containers
• Compacts easily

Light Management

Maximizing Natural Light

• Clean windows regularly
• Use reflective surfaces (white walls, mirrors)
• Rotate pots weekly for even growth
• Remove curtains during day
• Prune nearby outdoor plants blocking light

Signs of Insufficient Light

• Leggy, stretched growth
• Pale, yellowing leaves
• Slow growth
• Leaning toward light source
• Leaf drop

Supplemental Grow Lights

When needed: North-facing windows, monsoon season, low-light situations

Options:

• LED grow lights (energy-efficient)
• Fluorescent tubes (affordable)
• Full-spectrum bulbs

Duration: 12-16 hours daily for vegetables, 8-10 hours for herbs

Watering Indoor Plants

General Guidelines

• Check soil moisture daily (finger test)
• Water when top inch is dry
• Water thoroughly until drains from bottom
• Empty saucers after 30 minutes
• Use room-temperature water

Indoor Watering Challenges

• Lower evaporation: Need less water than outdoor plants
• AC/heating: Dries air, may need more frequent watering
• Humidity: Mist plants occasionally or use pebble trays

Overwatering Signs

• Yellowing leaves
• Wilting despite wet soil
• Mold on soil surface
• Root rot (mushy roots)

Temperature & Humidity

Ideal Indoor Conditions

• Temperature: 18-25°C for most plants
• Humidity: 40-60% (Indian homes often suitable)
• Air circulation: Gentle fan or open windows occasionally

Seasonal Adjustments

Summer:

• Protect from intense afternoon sun
• Increase watering frequency
• Ensure good ventilation

Winter:

• Move away from cold windows at night
• Reduce watering
• Avoid cold drafts

Monsoon:

• Reduce watering (high humidity)
• Ensure air circulation to prevent fungal issues
• May need supplemental light

Fertilizing Indoor Plants

Organic Options

• Liquid fertilizers: Diluted compost tea, seaweed extract
• Vermicompost tea: Gentle, balanced nutrition
• Banana peel tea: Potassium boost

Schedule

• Bi-weekly: Liquid fertilizer during active growth
• Monthly: Top-dress with thin layer of vermicompost
• Reduce in winter: Plants grow slower, need less

Pest Management Indoors

Common Indoor Pests

• Fungus gnats: From overwatering; reduce watering, let soil dry
• Aphids: Spray with soapy water
• Spider mites: Increase humidity, spray with water
• Mealybugs: Remove with cotton swab dipped in alcohol

Prevention

• Inspect new plants before bringing indoors
• Quarantine new plants for 2 weeks
• Maintain plant health (healthy plants resist pests)
• Good air circulation
• Clean leaves occasionally

Harvesting Indoor Plants

Best Practices

• Harvest in morning for best flavor
• Use clean scissors
• Never take more than 1/3 of plant
• Harvest regularly to encourage growth
• Rinse before use (indoor dust)

Continuous Harvest Techniques

• Cut-and-come-again: Lettuce, microgreens, herbs
• Outer leaf harvest: Coriander, mint, basil
• Succession planting: Start new pots every 2 weeks

Common Problems & Solutions

Leggy, Weak Growth

Cause: Insufficient light

Solution: Move to brighter window, add grow lights, prune to encourage bushiness

Yellowing Leaves

Causes: Overwatering, nutrient deficiency, natural aging

Solution: Adjust watering, fertilize, remove old leaves

Mold on Soil

Cause: Overwatering, poor air circulation

Solution: Reduce watering, improve ventilation, scrape off mold, top with fresh soil

Plants Not Fruiting (Tomatoes, Chillies)

Cause: Lack of pollination indoors

Solution: Hand-pollinate by gently shaking flowers or using small brush
