Why dry air causes plant stress

Dry air speeds up moisture loss from leaves beyond what most houseplants can handle. In Indian cities, this hits during both summer and winter.

What's happening

Plants lose water through stomata via transpiration. In dry air, this accelerates — leaves lose moisture faster than roots can replace. The result: brown tips, crispy edges, curling, and leaf drop. Ferns, calatheas, and peace lilies are especially sensitive.

Why this happens

Indian summers in the north and centre drop humidity below 20% in April–May. AC removes moisture from indoor air year-round. Winter heaters dry rooms further. Even coastal cities develop dry microclimates in AC-heavy homes.

What usually helps

Group plants together — collective transpiration creates a humid microclimate. Place pebble trays with water beneath pots (without pots touching water). Move sensitive plants away from AC vents. A room humidifier during peak dry months makes a real difference for humidity-lovers.

What to expect next

Brown tips won't reverse on existing leaves, but new growth emerges healthy once humidity improves. Most plants show visible improvement within a week or two.
