Lesson 15:Specialised Gardens

Gardening

• The soil mixture for roof garden should be prepared by mixing equal parts of garden soil and cow dung manure.
• Leaf mould should be a welcome alternative to cow dung for its light weight and fluffy nature.
• Layout of the garden should be delineated on the roof with powdered lime, and the soil mixture should be spread 15-20 cm thick, leaving the paths lined with bricks.
• Bricks should be held together through cementing.
• A gap of 5 mm between two bricks should be left approximately at every 50 cm length to act as drainage hole.
• The soil mixture of the beds should be held back from draining out through these holes by spreading a double layer of close-knit nylon screen along the inner side of the brick lining.
• One kilogramme of oil cake, preferably from neem (Azadirachta indica) , mahua (Madhuca latifolia) or karaj (pongamia pinnata) seeds, one kilogramme of bonemeal and 0.05 m 3 of small charcoal bits should be worked in every 10 m2 of the newly prepared beds.
• The pH of the soil mixture should be maintained between 6.2 and 6.8.
