Kaushal Vikas Class 9 Chapter 2, Rooftop Gardening, shows how unused house or school rooftops can be turned into productive green spaces that grow fresh vegetables, cool the building, reduce air pollution and create a habitat for birds and insects.
What Kaushal Vikas Chapter 2 Covers
Planning, Site Visit and Layout (2.2–2.7) covers scoping the work, making a process chart, checking the roof during a site visit (placing heavy containers near the load-bearing edges, leaving a walking pathway), designing the layout, and preparing a Bill of Materials (BoM).
Pot Preparation, Sowing and Plant Care (2.8–2.9) teaches preparing the potting mixture, running a seed germination test, irrigation, and natural plant protection using neem spray, water spray and manual pest removal.
Harvesting, Storage and Packaging (2.10–2.13) covers harvesting at the right stage, storing and packaging produce for transport, and assessing your learning.
Checking the roof first: in the chapter’s example, the Grade 9 ‘Go-Green’ team at a government high school made sure the parapet wall was strong and asked the contractor who built the school how much load the roof could carry before planning their garden.
Choosing containers and tools: terracotta pots let air and moisture through and prevent waterlogging; plastic pots are light; grow bags are easy to move; cement pots are heavy and hold heat; wooden containers keep temperature steady. Tools such as the hand trowel, pruning scissors and watering can are listed with how to handle them safely.
Water and weeds: too little water causes water stress, when demand exceeds supply; too much suffocates the roots. Weeds are unwanted plants that compete with the crop and must be removed.

FAQ
Why are heavy containers placed near the edge of a roof garden?
Because the edges and beams of a roof bear weight better than the centre of the slab, as shown in Figure 2.1 of Kaushal Vikas Chapter 2.
How are pests controlled in the rooftop garden project?
Through eco-friendly methods: neem spray, spraying with water, and manual removal of pests.
Why are terracotta pots good for a rooftop garden?
They let air and moisture pass through, which prevents waterlogging around the roots.
