What to grow on a terrace in Kolkata?

Kolkata's humid climate suits pumpkin, bitter gourd, pointed gourd (parwal), and amaranth in summer. Winter (Nov–Feb) is ideal for cauliflower, cabbage, tomatoes, and peas. Monsoon suits cowpea and colocasia. Leafy greens like red amaranth are productive on Kolkata terraces year-round.
