Cafeteria and Terrace Herb Garden in Hyderabad

Since most of Hyderabad's usable soil is a thin red sandy layer over granite, a herb bed built directly on terrace screed rarely has enough depth for anything beyond a few weeks of growth. We build raised beds with their own drainage and a proper growing mix, sized to the load the terrace structure can carry, rather than laying soil straight onto the floor.

Timing beds around a short, heavy monsoon

July is Hyderabad's wettest month, averaging around 178 mm of rain over roughly 11 rainy days, concentrated into a season that runs from June to October against a mostly dry rest of the year. A herb bed without adequate drainage waterlogs fast in that window even though the annual rainfall total, at around 801 mm, sounds moderate on paper.

Outside the monsoon, the same beds need daily attention through Hyderabad's hot months from March to May, when herbs like coriander and mint bolt or wilt quickly without shade netting and more frequent watering than the cooler months need.

A shorter growing window than it looks

Winter, when Hyderabad's average temperature drops closer to 22°C in December, is when leafy herbs such as coriander, mint and basil grow fastest on a terrace bed, well ahead of the March heat that makes the same herbs bolt or wilt.

Basil struggles most in Hyderabad's peak summer, wilting within a day without a shade net, while coriander and mint tolerate the heat somewhat better provided the raised bed's drainage keeps the roots from sitting in standing water after a sudden shower. Raised beds are cleaned out and refreshed with new growing mix roughly once a year, since a shallow bed's soil structure breaks down faster under Hyderabad's summer heat and monsoon cycle than a deeper ground bed's would. Whichever herbs go in, the bed is checked after the first heavy monsoon downpour of the season, since that first burst of rain is what most often reveals a drainage gap the dry months never exposed.
