Climate: Kolkata's high natural humidity makes it outstanding for foliage plants. Boston fern, philodendron and pothos grow with extraordinary vigour here year-round. Full East India Guide
Local Growing Conditions
Kolkata, sitting in the Hooghly river delta, is genuinely one of the most consistently humid major Indian cities, closer in year-round moisture to Guwahati than to the drier north Indian plains cities like Delhi or Kanpur, which makes tropical foliage plants perform particularly well here with comparatively little extra effort. Its many older colonial-era buildings also tend to have narrower, more enclosed balconies than the more open, modern construction common in newer Indian cities, meaning available light is often the real limiting factor for Kolkata balcony gardeners more than climate itself.
