Vegetable Roof Gardens

Who says people need land to grow vegetables? All you need is a roof that is strong and flat enough to support a garden.

Four things are needed to follow this design for a small rooftop garden. One thing, as we said, is a roof that can support the weight. Another is grass cuttings. The third thing is a sheet of plastic on which to spread the cut grass. And the last thing is a box about eight centimeters deep and made out of four pieces of wood.

Once we are sure that the roof is good, cut and collect some grass. Then lay down the plastic where the garden box will go. The four-sided box can be as long and as wide as needed. Place the box on top of the sheet of plastic. Then fill it with the cut grass. Next, add water and walk on the cuttings to press them down.

After about three weeks, the rooftop garden is ready for planting. Put the seeds directly into the wet grass cuttings. This garden is a good place to grow peas, tomatoes, beans, onions and lettuce. If the box is deep enough, potatoes and carrots will also grow.

It is important to keep the grass wet until the plants begin to grow. When the plants are growing, they will need watering every day, unless there is rain. And they will need some liquid fertilizer. If the chicken waste is available, then liquid fertilizer can be made. Rooftop gardens need a lot of water. Also, seeds and new plants must be protected from insects and birds.
