Terrace and Rooftop Vegetable Farming in Kolkata

Recognised as a wetland of international importance in 2002 and protected under a dedicated state law passed in 2006, the East Kolkata Wetlands treats a large share of Kolkata's sewage naturally while its farmers grow the vegetables listed above on that same land, a working demonstration of what this delta's soil and climate can support.

We build a rooftop bed's crop list around whichever of these vegetables suits the terrace's sun exposure and the season it is planted in, rather than defaulting to a generic seed packet selection.

Raised beds against a wet season that arrives on schedule

A rooftop vegetable bed needs real drainage underneath it, not just soil in a container, or the roots sit wet long enough during the rains to rot before the crop matures.

Most of the vegetables on this list actually do best in Kolkata's cooler, drier months, matching the pattern the wetland farms follow a short distance from the roof they are grown on here.

Pest pressure specific to a rooftop bed

Aphids and caterpillars are the most common problem on cauliflower and eggplant through the cooler months, while fungal leaf spot is the bigger risk once the rains set in, so the pest check through the visit changes with the season rather than staying fixed.

A rooftop bed also dries out faster in full sun than a ground-level plot, which we account for in the watering schedule handed over with the crop plan.

Succession planting through the growing months

Rather than planting an entire bed at once and harvesting it all together, we stagger sowing across a few weeks so the bed keeps producing over a longer stretch instead of delivering everything in one short window and then sitting empty.

That staggering also spreads out the pest and disease checks, since not every plant in the bed is at the same vulnerable stage at the same time.
