How Many Plants Do You Need?

NASA recommends 1-2 good-sized plants per 100 square feet of indoor space for optimal air purification. For a typical Indian bedroom (120 sq ft), 2-3 plants are ideal.

Placement Tips for Maximum Benefit

• Bedroom: Snake Plant, Aloe Vera (release oxygen at night)
• Living Room: Areca Palm, Rubber Plant (make visual statements)
• Bathroom: Peace Lily, Boston Fern (love humidity)
• Kitchen: Pothos, Spider Plant (tolerate temperature fluctuations)
• Home Office: Dracaena, Bamboo Palm (reduce fatigue)

Common Mistakes to Avoid

• Overwatering (leading cause of death for indoor plants)
• Keeping plants in dark corners without assessing light needs
• Using unfiltered tap water with high chemical content
• Neglecting to dust leaves (dusty leaves can’t photosynthesize properly)
• Not repotting when plants become root-bound
